The mission of the Water Institute at UNC is to provide
global academic leadership for economically, environmentally,
socially and technically sustainable management of water, sanita-
tion and hygiene (WaSH) for health and human development and
to be a vibrant, interdisciplinary center that unites faculty, students
and partners from North Carolina and developed and develop-
ing nations worldwide. We develop solutions to improve water,
sanitation and hygiene for all. We make our work relevant and
practical by linking research with policy and practice. Since our
launch in 2010, we’ve shared new insights and knowledge that
have informed the work of local and national governments and in-
ternational aid organizations—including the World Bank, World
Health Organization, and UNICEF.
Our four main strategic functions are research, teaching and
learning, knowledge information management, and network-
ing and partnership development. Through research, we tackle
knowledge gaps that impede effective action on important WaSH
and health issues. We respond to the information needs of our
partners, act early on emerging issues and proactively identify
knowledge gaps. By developing local initiatives and international
teaching and learning partnerships, we deliver innovative, relevant
and highly accessible training programs that will strengthen the
next generation’s capacity with the knowledge and experience to
solve water and sanitation challenges. By identifying or develop-
ing, synthesizing and distributing relevant and up-to-date knowl-
edge and information on WaSH, we support effective policy and
decision-making that protects health and improves human devel-
opment worldwide, both predicting and helping prevent emerging
risks. Through networking and partnership development, we bring
together individuals and institutions from diverse disciplines and
sectors, enabling them to work together to solve the most critical
global issues in water and health.

MONITORING is data collection and analysis
to guide implementation and progress over a period of time.
Monitoring answers the questions:
Are we on track to deliver what we promised?
Where are we behind or ahead?
Where are the opportunities for improvement?
EVALUATION is the systematic and objective
appraisal of a project/program (usually by a third party) to
assess impact and guide future policy. Evaluation answers the
questions:
How did we get here?
How would we improve next time?
LEARNING is the systematic process by which
insights from monitoring and evaluation are applied to
improve programs and interventions.

1.1.
Access to safe water, basic sanitation and good hygiene (WaSH) are critical to human
health and development. In recognition of the fundamental importance of these services,
governments, bilateral and international aid organizations, philanthropic foundations
and nongovernmental organizations (NGOs) have prioritized investments in WaSH
programs in recent decades. Monitoring, evaluation and learning (MEL) techniques play
an important role in tracking and enhancing the impact of WaSH programs.
Earlier efforts focused on expanding access to basic services, which was reflected in
international targets for water and sanitation coverage as expressed in the Millennium
Development Goals and other international development agendas such as the International
Drinking Water Supply and Sanitation Decade (1981-1990). In recent decades, there is a
growing recognition of the need to improve the quality of WaSH services, maximizing
their widespread and continuous use (not just “access”) and ensuring continuity
and sustainability over time. In addition, there is a growing recognition that not all
investments in WaSH services are equally effective and that some programs achieve far
greater impact per dollar invested than others.
In light of these recognitions, WaSH implementers and funders seek to improve
their programs and investments to maximize impact and efficiency—more specifically,
to provide water that is safe and reliable in adequate quantities to meet users’ basic needs
and to do so on a sustainable basis. This implies the need to ensure adequate chemical and
microbial quality of water for consumption, both at the source and at the point of use, in
contexts where continuous piped water at the home is not regularly available. In terms of
sanitation, this means ensuring that populations have access to and regularly make use of
improved sanitation facilities that meet their needs (with respect to functionality, privacy,
safety, and accessibility), and that excreta are safely disposed of to minimize the likelihood
that they will subsequently contaminate the human environment. In terms of hygiene,

this means ensuring that populations have access to and make use of basic handwashing
supplies such as soap and water, a goal with a major behavioral component.
Implementers increasingly have prioritized funding of water, sanitation and hygiene
together in recent decades, recognizing the synergistic interactions among interventions
in these areas. With respect to all dimensions of WaSH, implementers and funders are
interested in improving not only the quality and coverage of services—and their continuity
and sustainability over time—but also the cost-effectiveness of these services and their
delivery, in order to maximize the impact of programs with finite resources. Funders and
donors also are increasingly seeking to achieve these improvements in collaboration with
local governments and to credibly document the impacts of their activities.

1.2.
The Sustainable Development Goals (SDG), agreed upon in 2015 by the
United Nations General Assembly, include an emphasis on improving
the quality of WaSH service delivery, as well as on expanding access
to these services. Goal 6 (“Ensure availability and sustainable
management of water and sanitation for all”) calls for, among
other targets, several related to water, sanitation and hygiene (see box).
The World Health Organization/UNICEF Joint Monitoring
Programme for Water Supply and Sanitation has developed indicators and
operational definitions associated with these targets that call for safe water
to be free from microbial and priority chemical contaminants and to be
reliably available in adequate quantities close to home. These indicators
and definitions also call for adequate sanitation that hygienically separates
excreta from human contact and includes safe disposal.
Achieving these targets will require substantial increases in access to
basic WaSH services, especially as populations continue to grow; it will
also require WaSH implementers to deliver more services of higher quality
more effectively than ever before. Many program, project, national and
global monitoring initiatives are being improved and adapted to address
SDG priorities; and new monitoring initiatives are being developed.1 Data
experts expect billions of dollars of investment in monitoring initiatives
and new data collection during the SDG era.2

The dedicated SDG targets provide a useful framing and policy justification for actors
at the program, subnational, national and global levels to achieve universal coverage of
basic water and sanitation and to improve services. Achieving these targets and priorities
will require more and better evidence from project, program, subnational and national
monitoring data. Such evidence normally contributes to better service delivery outcomes,
but these data are often evaluated in a limited capacity where there is more added value
than present analyses derive and/or data are low quality. Improving the quality of
monitoring data and conducting service delivery research using monitoring data may lead
to greater insight and opportunities to improve water and sanitation services in the SDG
era. •
HISTORY OF MELIn 2010, the Conrad N. Hilton Foundation (CNHF) launched its five-year Strategy
for Sustainable Safe Water Access. Although its specific language was updated during the
strategy period, its broad aims remained constant—to provide sustainable safe water access
for one million people by 2015. As part of this strategy, CNHF sought to fund a greater
diversity of water programs (with more varied implementation approaches) in both West
Africa and other regions and to document the impacts of these programs more rigorously.
While the contribution of earlier programs such as CNHF’s West Africa Water
Initiative to the expanding coverage of water and sanitation services was likely
substantive, documentation of these efforts was limited and the implementation methods
used (i.e., boreholes with handpumps, etc.) were largely perceived by CNHF to be
conventional, in tension with the foundation’s desire to foster innovative new approaches
alongside proven existing methods.
In mid-2012, CNHF provided support to the Water Institute (WI) at the
University of North Carolina–Chapel Hill (UNC) to create a monitoring, evaluation
and learning (MEL) framework for its global safe water portfolio in response to a growing
need to document and enhance the impact of its programs. The WI’s proposal emphasized
the use of continuous quality improvement (CQI) methods to leverage monitoring and
evaluation (M&E) data for improvement in WaSH programs, something that had not
been done previously in the WaSH sector.
When the WI began reviewing CNHF’s water program, the foundation was
providing financial support through grants to eight implementing partners, plus several
knowledge and advocacy partners. Of the implementing partners working in the seven
countries receiving funding from the foundation, most were conducting varying levels

of monitoring and/or evaluation activities (e.g., post-implementation monitoring
surveys by WaterAid and the WaSH Bottleneck Analysis Tool by UNICEF). Grantees
were conducting monitoring and evaluation activities and programs that were designed
for internal purposes and would have been very difficult to export and scale to other
programs and projects.
At the September 2012 Hilton Foundation Grantee Convening in Accra, Ghana,
the WI gathered information from grantees about the top common challenges they were
facing: functionality, sustainability, urbanization, financing, water quality and the need for
systematic and targeted advocacy efforts and capacity building. In addition, a lack of data
from all project and program levels, including from the community level, was identified
as a common challenge. The lack of robust or credible data remains a problem across the
sector today.
Grantees indicated that monitoring at the community level is difficult
and that the traditional practice of M&E is conducted at the project level but not the
community level. Also, grantees agreed that existing monitoring tools are too
numerous and confusing to meet their needs. Often, different monitoring activities
were expected by multiple stakeholders (donors, government and other organizations),
leading to implementers simultaneously conducting multiple monitoring efforts using
different frameworks and methods to track similar projects in a given setting. Specific
challenges of monitoring include too many or too few indicators as
well as a lack of common operational definitions and methods for
measurement (e.g., how to count beneficiaries). Finally, the grantees focused on the
overall perception of M&E and its value to their work They stated that M&E exercises
often had little impact on programs and projects and that monitoring for
the sake of monitoring was of little value and often lacked purpose.
During the initial convening as well as in subsequent surveys, CNHF grantees
revealed that they wanted M&E processes built in from the start of projects and programs
so they could track progress from the beginning. They also requested a systematic way to
evaluate and learn from their WaSH projects with simple M&E tools and methods, which
would mean using a few critical indicators and cost-effective ways to measure and prove
causality. Finally, they requested that time, capacity building and funding be properly
allocated to allow for dedicated M&E.
After the convening of the grantees, the WI conducted a thorough literature review,
a review of grantee M&E frameworks and indicators, a sector-wide search for common
indicators and a consultation with WaSH experts and leaders. The core set of WaSH
indicators was presented to CNHF and its grantees at a closed meeting at the 2013 UNC
Water and Health Conference. The set of core indicators was designed to be simple (hence
6 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
only 21 indicators were chosen), measurable (the WI also presented working definitions
for each indicator) and relevant across all WaSH, not just water projects and programs. A
few individuals from grantee organizations felt the indicators were not tailored enough to
the needs of their projects and were vocally against the draft indicator set. •

Sustainability of community water systems has long been a concern for WaSH-
implementing organizations. Breakdowns of water systems are known to occur frequently
in low- and middle-income countries, resulting in a discontinuity and/or absence of
services that can have implications for human health and development.
In seeking to increase access to water supply over the last 50 years, it has perhaps
been natural for international support agencies, NGOs and sector experts to focus on
hardware and technology. It was easy to see that drinking water from ponds, open streams
or unprotected shallow wells without treatment was dangerous, and it seemed that the
biggest obstacle to a safe water supply was the lack of boreholes, pumps, pipes and/or
treatment systems. Such a view of the problem also suggested that international aid had

with CNHF grantees, several lessons were learned from the monitoring data collected,
the experiences of WI staff and CNHF grantees, and from additional projects and tasks
requested by CNHF during the grant period. Five of the most salient are, in summary:

great potential to solve the problem; foreign assistance could, with relative ease and speed,
purchase capital equipment and well-drilling expertise to drill a large number of boreholes
in the neediest areas of rural Africa and Asia. A frequent model for assistance in water
supply relied on an external support agency to provide some or all of the initial capital to
build the system, while leaving operations and maintenance to community management.
It was implicitly assumed that communities would recognize the enormous value of the
water supply and organize themselves to manage the system.
It has since become clear that people can be denied sustainable access to
safe water in at least two ways other than a lack of technology to assure
a good water source nearby. One is contamination between the water source and the
household, discussed further in Lesson 2. The second is perhaps the toughest challenge in
assuring sustainable and safe water supplies: frequent breakdown of existing systems due
to insufficient management capacity for the water supply at local levels. Villagers staring
at a broken handpump are no better off than villagers with no handpump at all—even if
thousands of dollars were provided to drill the borehole.
While management of a “simple” rural water supply may not require high levels of
technical expertise, it does have certain basic institutional and financial requirements that
have been widely neglected in practice. In addition to access to a competent mechanic,
sustainability requires such social assets as trust, accountability, incentives to maintain
and repair systems, and the ability to raise funds to cover running costs and effect repairs.
Increasingly, support agencies have come to recognize the importance of these “software”
issues and are giving more attention to local-level capacity building and support.
Recent research by the WI has explored the relationship between water system
sustainability and high-functioning management systems. A recently reported WI study
on handpump sustainability in rural Ghana3 where CNHF grantees had implemented
projects revealed a link between water source functionality and management determinants
(presence of identifiable management, access to tools and spare parts, savings, collection
of a tariff and external technical support). The study considered a wide range of
hydrogeological, technological and institutional variables calculated from data collected
from 1,509 water sources serving 570 communities in the Greater Afram Plains in Ghana.
Villagers staring at a broken handpump are no better off than villagers with no handpump at all—even if thousands of dollars were provided to drill the borehole.

Communities with identifiable management were more than twice as likely to have
functional water points than communities without an identifiable management system.
A Bayesian network model was developed to identify the determinants of
functionality. The authors found that nearly 80% of water points were functioning when
visited, which underlines the key role of functionality of existing systems in assuring
access. Eighty percent functionality suggests that 80% of the communities are enjoying
a functioning water supply, but it also means that one in five communities do not have
access to a functioning water supply at the moment, despite the large investments made
to provide one. Furthermore, in most cases, the damage is far from irreparable, leading to
a performance focus upon minimizing the time the system is out of service. It is perhaps
not surprising that management capacity is a key determinant of functionality, through
minimizing the overall downtime of the system.
The WI study found that a base starting functionality of 72% (i.e., nearly
¾ of the systems working at the time of a spot check) could be increased to 97%
with optimal management systems and available tools. The Bayesian
model suggests that effective tariff collection and a management team identifiable in the
community are both highly correlated with working systems. Both tariff collection and
availability of tools may be as significant as the model suggests or may be indicative of
other management factors that account for higher functionality.
In addition, WI researchers used qualitative research methods to investigate factors
that affect the sustainability and functionality of community-managed drinking water
systems. A WI researcher developed a set of rehabilitation pathways4 to examine the steps
in the process of initiating and completing a water system repair, in order to facilitate
the identification of weak links in the chain. Participatory field research was conducted
in World Vision (a CNHF grantee) communities in Kenya, Ghana and Zambia.
Key findings included the importance of directing management training at the entire
water management committee (not just one or a few water committee members) and
encouraging communities to mobilize resources proactively rather than reactively for
quicker repairs of breakdowns.
Adoption and documentation of such a framework during systems operation could
provide the first steps in local management CQI that can eventually yield the simple—yet
high-functioning—systems required to keep safe water flowing in rural communities.
Research examining the link between sustainability and successful management
systems, both within and outside of the WI, indicates that building and maintaining the
capacity of water management entities may be essential to maximizing the long-term
sustainability of water systems.3,4 It is important for WaSH implementers to recognize
this link and allocate the resources necessary to create and maintain highly capable water
management entities.
From the first identification of a breakdown to the completion of its repair, this research identified the actors involved, the constraints that slow rehabilitation and those factors that can prevent repair or rehabilitation from occurring altogether.

3.2.
From the very beginning of its involvement in WaSH, CNHF has focused upon drinking
water quality. The rigorous survey work and analysis done in this study strongly suggest
a consistent pattern of drinking water quality challenges faced by those served by CNHF
grantees, summarized in Table 1, Figure 1 and these two statements:
1. The majority of water sources developed by Hilton grantees in
sampled project areas offer water of acceptable or low risk. These
sources conformed with WHO guidelines for either microbial safety (0 bacteria/100
ml) or “low” microbial risk (1-10 bacteria/100 ml). In Ghana 55% of sources fell into
one of these two categories, while in Ethiopia and Burkina Faso about half did (57%
and 64% respectively).
2. The significant majority of water samples stored in houses in these
same areas represent water of dubious quality. They fell into WHO’s
categories of intermediate risk (11-100 bacteria/100 ml) or high risk (>100
bacteria/100 ml.) In Ghana 76% of households in project areas had water falling into
one of these two categories, while in Ethiopia and Burkina Faso, about 80% and 68%
did, respectively.
In short, half or more of the acceptable or low risk water available from the source is
significantly contaminated by the time it is available for home use.
Assessment of multiple CNHF grantees and data collection in six countries revealed
widespread water quality challenges. In Ghana, Burkina Faso and Ethiopia, data collected
in 477 communities where CNHF grantees had implemented projects revealed detectable
E. coli contamination in samples from 60%, 48% and 56% of community water sources,
Sustainability of sanitation and hygiene services is also a major concern and has
major behavioral components; effective community management may play a role in the
long-term sustainability of these services as well. Several factors potentially related to
community management have been linked to the sustainability of rural sanitation services,
including community demand, local financing, and dynamic operation and maintenance.5
Additional work to explore the role of community management in the sustainability of
sanitation and hygiene services is needed and is recommended as a critical research area in
support of countries’ efforts to maximize progress on SDG 6.

water for consumption contained detectable E. coli in all three countries and 40-60% of
these samples were in the high risk category. Furthermore, stored water samples from
households using improved sources were not dramatically less likely to be contaminated
or in the high-risk category than were sorted water samples from households using
unimproved sources.
These findings suggest that across multiple contexts, microbial water quality remains
a serious concern, particularly at the household level, and that many of the water quality
benefits provided by access to improved community water sources may be undone by
secondary contamination during unsafe transport and storage. Subsequent work in other
countries and recent systematic reviews suggests that these results are not unique to
CNHF grantees but characterize rural and peri-urban water quality challenges across a
wide range of low- and middle-income countries. These challenges are rarely captured by
current M&E approaches implemented by many WaSH programs, which rarely collect
water quality samples from sources after initial implementation or from households in
program areas. In the future, WaSH programs should seek to prioritize monitoring and
improving water quality, with a particular emphasis on microbial water quality at the
household level.
These analyses of baseline data provided a starting point for CQI in Ghana, for
example, through an intervention to promote safe water storage containers that are not
susceptible to contamination as people dip their hands with cups or bowls into the water;
these containers are defined as those with a narrow mouth and tight-fitting lid, from
which water is extracted by pouring or dispensing from a tap9 (Figures 2a and 2b).
Among homes that adopted safe water storage containers, the percentage of households
with water that met WHO guidelines increased approximately 70% (from 17% to 29%).
Nevertheless, the challenge of household water quality remains substantial. Even
under the best circumstances in Ghana, where safe water storage was used for water
coming from an improved source, over half the samples were of intermediate or high risk.
The results strongly suggest a need to consider a clearer understanding of the full water
transport chain from well to storage container with a view towards safeguarding quality
along the entire route. Safe storage was correctly identified as one key factor in improving
water quality at the home, but the evidence strongly suggests it is not the only one.

3.3.
The Water Institute’s 2013-2015 assessment of CNHF’s Sustainable Strategy for Safe
Water Access included a detailed review and assessment of CNHF grantees’ M&E
frameworks and data where available. It revealed that while many CNHF grantees
had strong programs with a substantive impact on improving access to improved water
sources, none had M&E systems in place that were capable of robustly documenting
their programs’ impact on sustainable access to safe water, as defined by CNHF. Very
few grantees were collecting accurate beneficiary numbers, no partners were consistently
collecting water quality data after installing water points or at the household level, and
very few were collecting data from follow-up visits or tracking service level provision
on a regular basis. Essentially, good or SMART10 monitoring was limited across CNHF
grantees and deficient across the sector in general. Traditional monitoring conducted by
nongovernmental organizations often involved collecting monitoring data for internal
reporting and donor facing progress reports, where outputs were the only metrics
being tracked and reported (e.g., number of water points constructed, the number of
beneficiaries, the number of meetings held with the government) and were usually based
on best estimates and averages. Very few grantees were reporting to or coordinating with
local or national governments.
Three widespread challenges faced by most CNHF grantees were:
1. documentation of the number of people their program served,
2. the quality of water and sanitation services those people received,
and
3. the continuity and sustainability of these services over time.
In most cases, programs used nominal estimates of program coverage, based on
assumptions (e.g., “one handpump serves 300 people,” or “the entire population of this
community will benefit from this new water source”) rather than on credible monitoring
data. In some cases, monitoring data were used but were not collected in a robust manner,

Wherever the other opportunities lie to improve the safety of drinking water, the results
suggest that CNHF grantees and the WI have been correct to act on the obvious truth
that water quality at the household level, and not just at the source, is the key parameter
on which to focus for improvement—and the baseline data suggest the magnitude of the
problem across Africa.

leading to dramatic overestimation of program impact; for example, some grantees used
survey data to estimate the population served, but used methods which incorporated
considerable upward bias, leading to overestimation of total daily users of their programs
by an estimated 200-500%. In all cases, there was a tendency to assume that “proximity
equals access” (i.e., that all individuals living near a water source benefited from that
water source, regardless of the number of people actually using the source, whether it was
working and whether it was producing safe water).
In the case of water quality, many programs conducted water quality analyses at some
point in time, but few grantees had well-designed monitoring systems capable of detecting
chemical and microbial hazards in source and household water. Specifically, grantees
implementing groundwater systems frequently performed a one-off test of chemical
(and sometimes microbial) water quality on a new well before installing a handpump but
rarely conducted water quality testing of existing systems to assess the safety of the water
produced. In no case did CNHF grantees conduct testing of the water consumed by
program beneficiaries at the household level.
Likewise, monitoring of the continuity and sustainability of services was insufficiently
robust in many cases. While some grantees collected data on the functionality and uptime
of the infrastructure they had implemented, many did not. Where data were collected,
the M&E methods used were often insufficient to provide an accurate picture of the true
number of hours per day or days per week that users received service. Likewise, reliable
data on the proportion of water and sanitation facilities that were functional at any given
time were often lacking.
These deficiencies in M&E systems appeared to be characteristic of
many implementers in the broader WaSH sector, rather than of CNHF
grantees in particular. While all grantees conducted some form of M&E and all
believed their activities to be adequate, few were in a position to credibly document
their contributions to CNHF’s Sustainable Safe Water Strategy. This suggests that
many WaSH implementers sectorwide are likewise poorly positioned to document their
contributions to the WaSH-related SDGs.
Furthermore, the assessment of CNHF grantees revealed high performance
in many areas but with a greater emphasis on compliance than
improvement. There may be value in further learning activities, such as basic training
in quality improvement methods, with the objective of fostering an improvement mindset
among CNHF grantees in particular, and the WaSH sector in general, in order to
promote the data-driven improvements needed to increase program quality and efficiency.

Over the past three and a half years since the WaSH MEL project began, it has become
increasingly evident that many of the issues CNHF grantees identified as main challenges
in implementing robust M&E in their programs also present challenges for the WaSH
sector at large. The sector lacks a core set of validated methods and
standard indicators for WaSH M&E that can be used throughout the sector,
including by governments. When the WI began to build the WaSH MEL framework
for the CNHF and its grantees, researchers conducted an extensive literature review,
compiled a list of all grantee indicators in use at that time, reviewed indicators used by
other WaSH organizations sector-wide and consulted with sector experts and advisors on
best practices. The aim was to develop a parsimonious core set of indicators that would
be simple to measure but robust enough that when analyzed would provide valuable
insights into causes and correlations of multiple variables relevant to all WaSH projects. In
addition, the WI leveraged insight into discussions around the SDGs (not yet finalized at
the time) to align the core WaSH MEL indicators as closely as possible with the nascent
SDG targets related to drinking water and sanitation.
A shift in the WaSH mindset needs to occur as the grantees highlighted in the first
convening, as to “why we do M&E.” Traditional M&E simply provides a measure of
whether a project is succeeding or failing. Data was often collected in traditional M&E
without a clear purpose, which led to poor quality, unused, neglected data and a lot
of wasted resources. Adding learning to traditional M&E programs shifts
the focus to improving and increasing the value and impact of WaSH
investments. The learning component of MEL is key: Improvement is a continual
cycle that never stops.
3.3 .2 . The Data Dilemma
3.3 .3 . From M&E to MEL
The core set of WaSH MEL indicators is continually being refined and updated to
incorporate new SDG indicators and indicator guidance developed by the JMP and
others, as well as new insights from the field and from current research. These indicators,
together with tools and methods that include validated surveys, water quality testing
methods, quality assurance/quality control (QA/QC) protocols, and data analysis
methods, constitute a robust WaSH MEL framework for monitoring and evaluating
WaSH projects and programs. The toolkit includes the core indicators; community,
household, water point and institutional facility surveys designed to be compatible with
a variety of mobile survey tools currently used in the WaSH sector, including Akvo

FLOW and mWater; a mobile water quality testing field kit; training manuals; in-person
enumerator training modules; QA/QC protocols and robust data analysis (incorporating
both basic summary statistics and more advanced regression analysis) and reporting
methods. The tools and the toolkit are not only meant to enable WaSH implementers
to assess performance and identify problems, but also to leverage advanced analysis in
order to provide valuable insights and knowledge about the root causes of problems and
the greatest opportunities for improving WaSH services at the project, program and
national levels. The MEL framework is designed to be usable by any WaSH
organizations and scalable for subnational and national systems, in
addition to being suitable for CNHF grantees.
3.3 .5 . The Focus on Improvement
Traditional M&E uses data for reports, presentations and grant proposals. A complete
MEL framework requires that data must be turned into improvement via action. The WI
introduced CQI to WaSH through the CNHF-funded MEL project. CQI provides a
systematic, data-driven, improvement-focused means for bringing about change. Instead
of relying on personal opinion, business as usual or peer pressure, CQI is a proven method,
and as the name suggests, a continuous commitment to improving outcomes. The shift in
the WaSH sector mindset needs to take place here, at the point where the data is collected
and analyzed, and the data need to provide fuel for the next opportunity for improvement.
Individuals and organizations can then take the necessary actions to target, improve and
sustain the outcomes.

3.4.
Over the last 30 years, the WaSH sector has been characterized by its emphasis on
outputs and hardware without similar achievements in desired service delivery outcomes.
Monitoring and evaluation processes supporting implementation have been inadequate
to effectively measure and improve performance. The sector recognizes that “business as
usual approaches” will not achieve desired outcomes in terms of sustainability and that a

16 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
new, systems-based approach is needed to improve WaSH program implementation and
performance. CQI methods and tools have proven to be powerful in addressing complex
problems in the manufacturing and health care sectors and have recently been shown to
improve outcomes related to drinking water supply and water quality in rural low-income
country settings.
3.4 .2 . Compounding the Problems with a Project-Oriented Approach
More than a decade ago, Lockwood, Bakalian and Wakeman11 characterized five
main groups of factors that significantly affected the post-project sustainability of
WaSH systems: technical, financial, community and social, institutional and policy,
and environmental. This work cited several prior sources that had identified similar
influences. These factors are widely agreed on in sector-wide sustainability conversations;
however, in practice, a project-vs.-services mindset continues, in which implementers
focus on maximizing outputs (completed projects) at the expense of tracking and
improving outcomes (sustained service delivery). This mindset may well have led to
widespread failure of WaSH systems, as recognized in statistics pointing to water point
or sanitation system access and use, or household water quality. One way to address this
project-based mindset is to change the means and measurements of success—not just for
“projects” but for implementing organizations themselves—thinking past the project and
hardware outputs to a systems mindset that seeks to ensure universal, sustained services by
improving the systems that deliver those services.
3.4 .3 . CQI: A Systems and Process-Oriented Approach to Complex Problem Solving
Applying CQI to the WaSH sector offers an opportunity to adapt to the task of solving
complex problems and delivering cost-effective improvements in service delivery. The
CNHF-funded MEL pilots in Ghana and Burkina Faso and the Water Quality Study
conducted in Ethiopia have applied CQI methods to the complex institutional, technical
and behavioral challenges of improving the uptake and impact of rural water, sanitation
and hygiene programs, something that has not been done previously in the WaSH sector.
CQI employs a systems- and process-centered approach to redesign interventions in real
time by tracking and analyzing performance data in a tight implementation feedback loop
to achieve given overall objectives. In doing so, CQI pays for itself by reducing the risk of
unsustainable outcomes and through more effective targeting of scarce resources. Of equal
importance, CQI empowers implementers and other local stakeholders to analyze and
address problems through MEL rather than surrendering these responsibilities to external
evaluators. Those closest to the problem quickly learn what does and does not work and
can use that knowledge to scale up high-impact improvements in their interventions.
CQI enhances sustainable operation of WaSH systems through short cycles of M&E that inform data-driven adaptations to program design and management.

3 .4 .4 . CQI Enables Precise, Data-Driven Actions to Improve Outcomes
Employing CQI requires robust data, next-level analysis and an improvement plan
that involves all levels of an organization. Without a data-driven system or approach,
individuals and organizations are left to take a best guess at how to solve complex issues.
Trends and percentages are not able to identify root causes and correlations. For example,
in Ghana the data revealed that the majority of household stored drinking water was
in the high-risk category based on WHO Drinking Water Quality Guidelines. The
implementing organization used this information to identify drinking water quality at the
household as a target issue for improvement.
To address the issue of water quality at the household, the WI and World Vision
Ghana started by designing a safe storage container with a stand. The design of the storage
container and the stand evolved as data was gathered from consumers about container
preference and usability. The design as currently distributed prevents hands from being
able to reach into the storage container (hands being a large contributor to contamination),
reaches above waist level to allow water to be poured into the top with limited back-
bending movements and sits above the ground in a stand to prevent goats and children
from knocking the container over. Subsequent monitoring rounds and data indicate
that household water quality was improved with the use of the newly designed storage
container and fewer households were categorized in the high-risk category for drinking
water quality.
Issues surrounding sustainability, water quality and community WaSH committee
management are often complex. Sometimes the problems are simple. If a part on a specific
type of handpump continually breaks, replacing it or repairing the part seems simple
and obvious. However, complex issues where solutions are not clear require a process-
focused approach to identify root causes and relationships to other variables in order to
make an improvement. Thousands of dollars are spent rehabilitating handpumps without
understanding or knowing the root cause of breakdowns and how to reduce water-
point downtime. Several tools used as part of CQI enables implementers to identify root
causes and identify relationships and pathways and impact on outcomes. CQI focuses
on breaking down each process and re-building the process to gain
efficiencies and improve the outputs and outcomes. CQI is a way to put data
into action to improve impact and outcomes.

3.4 .5 . CQI is Adaptive
Lessons learned from the CQI pilot project in Ghana were adapted to the Burkina
Faso context. After the WI worked with WaterAid, a CNHF partner working in
Burkina Faso, to conduct WaSH MEL monitoring, household water quality emerged
as an issue here as well. WaterAid chose to focus on addressing water quality. Using the
Ghana storage container as a starting point, WaterAid conducted further testing of the
container in rural communities in Burkina Faso. The storage container was adapted
to local preferences and distributed in households in monitoring areas. Using data and
evidence from other WaSH projects can accelerate learning in a new place. However,
adaptation relies on robust data and analysis. Without data and evidence, individuals and
organizations are not able to target improvement efforts and resources.
3.4 .6 . Effective, Targeted Improvements Require Data and Evidence
CQI is a way to immediately take action on both simple and complex issues and drive
improvements to increase impact and outcomes for everyone and ultimately the end user
and beneficiaries.
Data and evidence are necessary for targeting. If data and evidence do not exist,
lessons are hard to extract and improvements are nearly impossible to measure. Without
improvement, the same story remains: broken handpumps, abandoned water points,
unused toilets and open defecation. Investment in rehabilitation efforts and hardware
will be endless and cyclical without the ability to understand the causes and correlations
behind the WaSH bad-news narrative. Many individuals and organizations are very good
at problem diagnosis, but rarely are they able to provide evidence or solutions for complex
and even simple WaSH problems.
The WaSH MEL experience has demonstrated that implementation science methods
such as CQI can be used to enhance the impact of WaSH programs. Implementation
science (IS) methods, including CQI, have proven highly effective for addressing complex
challenges in manufacturing,12 service industries,13 health care14 and financial services.15
At the core of IS methods is the recognition that all work is done through systems and
all systems can be improved. Methods such as CQI rely on the systematic use of data
to improve processes. Briefly, quality improvement teams develop focused problem/
opportunity statements related to desired areas for improvement, collect and analyze
high-quality data on outputs and process indicators, and then develop improvement
packages based on the results of this analysis. These improvements are implemented on
an iterative basis to achieve adaptive solutions that maximize the quality and efficiency
of programs. CQI is different from conventional M&E because of its systematic

approach and its emphasis on analyzing data to identify and address the root causes of
complex performance issues, rather than simply tracking and quantifying outputs and/or
performance over time.

At the core of implementation science methods isthe recognition that all work is done through systemsand all systems can be improved.
Despite the successful application of IS and CQI methods to multiple sectors, these
approaches had not been previously applied to complex problems in global WaSH. The
WI and CNHF sought to explore the potential of “systems thinking” and IS tools in
general, and CQI methods in particular, to improve outcomes in WaSH systems affected
by complex challenges and problems. The first WaSH CQI pilot projects were conducted
in Northern Ghana, in partnership with World Vision (WV), a Hilton Foundation
grantee. The Water Institute trained a team of WV staff in CQI methods and a team
of enumerators to collect high-quality monitoring data in 230 communities where WV
had previously implemented water programs. The CQI team reviewed baseline data from
these communities and identified water source functionality and household water quality
as two areas they wished to target for improvement.
Using CQI methods, the WV team and WI staff analyzed the data and identified
root causes of poor household water quality, as well as the factors most strongly associated
with nonfunctionality of rural water sources. The CQI team used these results to
identify an improvement package to address poor water quality in stored household
water samples, as well as to increase the functionality of water systems in the target
communities. The package included safe water storage containers and training on their
proper use (to improve stored household water quality) and a combination of refresher
training for WaSH committees (committees responsible for managing water sources in
rural communities) and handpump repair tools (to improve water source functionality).
These improvement packages were implemented in a randomly selected half of the 230
communities in an iterative manner. Briefly, improvements were implemented in three
to six communities, follow-up data were collected, and the package was refined based
20 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
on revealed issues with the uptake or performance of the improvements. In this manner,
refined versions of the improvement package were developed and implemented in over
100 communities and more than 500 households. Significant improvements in household
stored water quality were observed in the households that were using a safe water storage
container at follow-up. Improvements in water source functionality were also observed,
although these were significant at the 90% (but not the 95%) confidence level. With
additional time, trends in water source functionality may become more pronounced.
Overall, this project demonstrated that IS methods such as CQI can be
successfully adapted from sectors such as manufacturing and health care
to WaSH, in order to leverage monitoring data to improve program outcomes. Work is
currently underway to adapt the safe water storage improvements from Ghana to Burkina
Faso, and WV and the WI are planning to launch additional WaSH CQI projects across
multiple contexts and multiple dimensions of water, sanitation, and hygiene.

Safe, sufficient sanitation and drinking water are important for human health, well-being
and development. Water and sanitation are recognized as human rights that are important
for addressing inequalities. The principle of progressive realization of human rights
requires that each government take steps “to the maximum of its available resources, with
a view to achieving progressively the full realization of the rights.” The United Nations
General Assembly’s 2010 Resolution on the Human Right to Water and Sanitation16 calls
upon governments “to scale up efforts to provide safe, clean, accessible and affordable
drinking water and sanitation for all.” Water and sanitation are also recognized in human
development policy—prominently in the Millennium Development Goals (MDGs) and
now in the SDGs.
Although coverage of the use of improved water and sanitation continues to increase
globally, there is much work to be done. Global coverage of drinking water and sanitation
is lower when accounting for the quality of services delivered to people. When accounting
for water quality, more than 1.8 billion people drink from a water source containing
fecal contamination.17 An additional 1.2 billion people use sources at an elevated risk of
Inequalities are considered the “unfinished business”of the MDGs and are explicit in the SDGs.

Further, global and national-level coverage estimates mask subnational inequalities.20
Analysis by the WHO/UNICEF Joint Monitoring Programme shows substantial
inequalities exist in many countries and many disadvantaged populations have been left
behind.21 Studies confirm that inequalities exist in other nonhousehold settings such as
schools and health-care facilities.22,23 Inequalities are considered the “unfinished business”
of the MDGs and are explicit in the SDGs. The MDGs did not include specific language
to prioritize inequalities.
Sustainable Development Goal 6 calls for the “availability and sustainable
management of water and sanitation for all” by 2030.24 The goals and targets for water
and sanitation seek to correct for the unfinished business of the MDGs. Many external
support actors, such as multilateral agencies, NGOs and foundations, are committed to
reducing inequalities and providing services to the “poorest of the poor.” For example, the
language in the CNHF Strategy for Sustainable Safe Water Access mentions “reaching
the vulnerable and ultrapoor.”
Achieving universal coverage and reaching the vulnerable and ultrapoor will require
innovation, thoughtful strategy, substantial improvements in monitoring and investment
targeting. To make improvements, it is important to understand the characteristics of
unserved populations in order to identify the best ways to provide them services. People
without WaSH are an increasingly small, disparate and diverse population, often living
on the margins of society in low- and middle-income countries. In the SDG era
(Figure 3), people most in need of WaSH services will be located in small
geographic pockets in hard-to-reach locations. These people may be located
22 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
where “sustainable interventions” and “market-based approaches” do not apply. As
indicated by the WaSH Performance Index,25 progress is unequal across countries and not
in the countries where people think it is. Specifically, some countries that currently have
low rates of coverage may be achieving faster-than-average progress with respect to the
rate of change in coverage levels, while some countries with high current coverage may
be achieving slower-than-average progress with respect to their peers. Thus, for example,
several countries in sub-Saharan Africa and South Asia, such as Niger and Pakistan,
appear to be making rapid progress relative to their peers at comparable current levels of
coverage (Figure 4). The challenge of the SDG era will be to determine
where these populations are and how governments and external support
agencies can use data to target them and provide them with services
effectively and efficiently.
National-level data should be further disaggregated to measure inequalities in
coverage among groups such as minorities and populations in rural areas. However,
organizations within countries (e.g., NGOs, external support agencies) must conduct
more targeted monitoring of people and populations at a subnational level. More
monitoring of nonhousehold settings is needed to gain further insight into the sufficiency
of WaSH in these settings. If proposed SDG targets with respect to reducing or
eliminating inequalities in coverage of water and sanitation are to be achieved, rigorous
monitoring, evaluation and learning will be necessary to identify characteristics of these

unserved populations so that existing and new projects can ensure services to the most
disadvantaged are provided.
Two stages of unserved targeting are needed. The first should focus on population-
level spatial characteristics. Stakeholders should use existing data to identify and prioritize
countries with low access and water scarcity. The WaSH Performance Index can be used
to identify low performing countries. Subnational data should be used where possible20
to identify areas that lack safe water and sanitation. Donors should consider funding
external support in these particular areas. The second stage should focus on household
and individual characteristics. Core wealth index indicators should be included to ensure
the ultrapoor and unserved are reached with services. Monitoring strategies also should
include indicators for other disadvantaged populations such as disabled and elderly people.
Rigorous monitoring, evaluation and learning will be necessaryto identify characteristics of these unserved populations.
It is also important that WaSH interventions reach nonhousehold settings such as
schools and health-care facilities to ensure universal coverage of services is achieved and to
ensure that certain populations are not marginalized. Following these approaches will help
ensure that the CHNF and partners are serving the unserved and helping to fulfill the
Human Right to Water and Sanitation. •

4 .1 .1 . Asking the Right Questions: Outputs, Outcomes and Process Indicators
In addition to being used to report the status, trends and levels of water and sanitation
services, monitoring data can be used to answer policy- and program-relevant research
questions.26 Relevant research questions can be developed in part by consulting findings
of prior monitoring efforts, prior evidence and theory of change models. Questions can
be tailored to the specific context, program or country and might explore, for example,
how water and sanitation interventions vary by setting, what processes are involved in
improving water and sanitation outcomes and what are the most important determinants
associated with higher levels of a given outcome.27 “Systems thinking” is important
to develop appropriate theoretical models for analysis, as environmental problems and
interventions are complex—with social, managerial, cultural, environmental and policy
determinants.28
Well-designed survey questions are also needed to answer policy- and program-
relevant research questions. Survey questions need to be scientifically robust, useful,
relevant, cost-effective and need to reduce bias where possible.29 While standard indicator
and survey question evaluation criteria are not available specifically for WaSH, use of the
SMART10 criteria may help ensure survey data is more reliable.30
4.1 .2 . Sampling and Sample Size Calculations
Many WaSH programs conduct M&E activities without considering the implications
of sampling and sample size. This oversight can threaten the validity and efficiency of
M&E activities in several ways. Generally, there are only two ways to obtain reliable
and representative information about a population of individuals, communities or
facilities: survey the entire population (i.e., go to every community, water source, latrine
and household) or survey a representative sample. High-quality monitoring of WaSH
programs generally requires multiple components such as in-person site visits, structured
observations and surveys at the community, household, and water and sanitation facility
levels, and water quality sampling and testing. Conducting these activities for an entire
population of communities, households or facilities would be cost-prohibitive for most
WaSH programs. If such an exhaustive census were proposed, it could only be conducted
a few times each decade, at most, to avoid consuming the entire budget of a typical WaSH
program, leading to a lack of timely data.
25C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D 4 . P R I N C I P L E S O F M O N I T O R I N G F O R I M P R O V E M E N T
By contrast, a representative sampling approach can provide M&E data representative
of an entire program area, even if a far smaller number of communities, households
and facilities are surveyed. To do this, the units (i.e., communities, facilities, and/
or households) to be sampled must be selected at random from the entire population.
Random sampling ensures that each unit has an equal chance to be selected. As a result,
the data obtained are representative of the entire population.
Sampling can be done in several ways. In the stratified random sampling approaches
typically used, program areas are divided into communities or enumeration areas and
several of these larger units are selected at random. Within each of the larger units,
individual facilities, households, etc., may also be selected at random. In this way, a large
population can be sampled without the need to visit a household in district A, then travel
50 km to district B to sample the next household, thereby increasing resource efficiency
while maintaining the validity of the sampling approach. When conducting any type of
random sampling, it is important to obtain a sample size that is large enough to achieve
the objectives of the monitoring activity, but not so large as to be prohibitively expensive.
In order to do this, sample size calculations must be performed, in order to obtain the
smallest sample needed to obtain M&E data fit-for-purpose with an adequate degree of
precision. Examples of methods for sampling and sample-size calculation for WaSH M&E
activities are provided on the WaSH MEL Virtual Learning Center’s modules on these
subjects: Sampling (http://www.washmel.org/module-4-relaunch/) and Sample Size
Calculation (http://www.washmel.org/module-6-relaunch/).
4.1 .3 . Measuring X and Y Variables
Another challenge many WaSH implementers face is the selection of the right variables
and indicators to monitor. In many cases, implementers will monitor only outputs (for
example, number of boreholes drilled, number of hygiene promotion workshops held,
number of community-led total sanitation triggering session participants). Monitoring
only outputs is problematic because it does not provide information on whether those
outputs achieved their intended objectives (improving the quantity and quality of water
available, reducing open defecation, etc.), and thus impact cannot be measured. In other
cases, programs measure only outcomes (water quantity per person per day, household
water quality, proportion of households practicing open defecation, etc.). Robustly

26 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
monitoring outcomes is valuable in that it enables programs to measure their impact.
However, tracking outcomes without measuring the intermediate process variables and
mediating factors associated with those outcomes can be problematic because it does
not provide information as to how to improve outcomes. Specifically, if an organization
determines that the functionality of water sources it has implemented is low, it will be
unable to address the problem without also collecting information on the determinants
of low water source functionality. Is functionality low everywhere or only in certain
regions? Are some source types more likely to be functional then others? Is functionality
associated with the presence or quality of management entities, or the availability of tools
and spare parts? These key determinants can provide important clues as to what actions
an implementer can take to improve a given outcome. In this respect, it is useful to think
of M&E data collection as a process of collecting both “Y” variables (outcomes) and
“X” variables (potential determinants of those outcomes). If implementers are able to
effectively collect both those Y variables most closely related to their program objectives
and the X variables that determine those outcomes, they are much more likely to obtain
data which will enable them to improve those key outcomes over time.
4.1 .4 . Methods of Data Collection
(Measurement, Direct Observation and Direct Response)
Several methods can be used to collect WaSH data, each with its own strengths and
weaknesses. Data can be collected at the household, community and facility levels and can
be obtained by direct observation or direct response.
The level of data collection selected for monitoring—either at the household,
community or water system level—will reveal different insights about systems and
water availability. For example, most nationally representative household surveys ask
respondents to identify the main source of drinking water used by the household, which
measures source use. If a nearby handpump is broken for an extended amount of time
and people use a protected spring a kilometer away, they will report that they use a
protected spring as their main source and indicate that the source is functional, thus
introducing a “survivorship bias” with respect to source type and functionality. While this
answer provides some information about availability, it does not provide representative
information about the functionality of all systems available to the user. Alternatively,
household surveys that ask about the reliability of the main water source used provide a
more accurate representation of the actual availability of water for the populations being
studied but still may be subject to survivorship bias.
Water system surveys provide information about particular water systems, which can
be valuable to actors who need to make decisions about how to invest in infrastructure

and track the status of assets. A limitation of such surveys is that they do not provide
reliable estimates of the population using water systems.31

Direct observation typically provides more reliable data, but direct response costs much less and is much less time consuming.
Direct observation typically provides more reliable data. Trained enumerators can
consistently evaluate water source types, sanitation facility types and other technical
details about infrastructure and services. Householders cannot always provide reliable
responses to questions about which they do not have appropriate expertise or knowledge—
such as the cause of a water system breakdown. Direct response, however, costs much
less and is much less time consuming for data collectors. Direct response also can reveal
information about people’s behaviors and habits that are important for informing service
delivery, revealing, for example, which water source a respondent used most recently.
4.1 .5 . Crafting Robust Survey Questions and Operational Definitions:
Avoiding Bias, Jargon, Constructs and Other Pitfalls
Crafting Survey Questions
Once indicators and variables have been established, suitable survey questions can be
adapted and developed. Survey questions should support the measurement of variables,
which should support the tracking of indicators to obtain data that meet survey objectives.
In addition to survey questions that directly support variable measurement, surveys
usually also include questions that capture metadata, stratifying variables, shadow
indicators and quality assurance / quality control (QA/QC) checks. Metadata (e.g., the
date the survey was conducted) and QA/QC questions (e.g., asking for a water point ID
a second time in order to ensure it is entered properly) should be included in all surveys.
Questions that capture stratifying variables should be included if there is a need to stratify
data across different regions or countries.
Standard questions that have already been validated should be used whenever
possible. Using validated standard questions increases the validity and comparability of
data. The following are recommended resources for standard WaSH survey questions:
• WHO/UNICEF JMP: Core Questions on Drinking-water and Sanitation for
Household Surveys
• USAID Demographic and Health Surveys
• UNICEF Multiple Indicator Cluster Surveys
• World Bank Living Standards Measurement Study
28 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
Surveys that already have been conducted either regionally or nationally may include
questions appropriate to the local cultural context. Examples of these surveys include:
• National censuses
• Demographic and health surveys
• Multiple indicator cluster surveys
• Living standards measurement studies
Although standard survey questions are a great resource and should be used
whenever possible, it will likely be necessary to create new survey questions as well. New
survey questions should be created with these guidelines in mind:
1. Use the simplest language possible.Avoid using language that is more complex than necessary. For example, asking “Is
there a particular spot in this house where people go to wash their hands?” is preferable
to “Is there a fixed location in the dwelling where hygiene activities are performed?”
2. Phrase similar ideas consistently between questions.Consistent phrasing helps make the survey clearer for the respondent. Asking one
question about the main source of drinking water in the dry season and then asking the
next season about the main source of drinking water in the wet season is much clearer
than first asking “What is the main source of drinking-water for members of your
household in the dry season?” followed by “Where do you most frequently go to fetch
water during the months when it rains a lot?”
3. Ask questions respondents will likely be able to answerEstimating liters per capita per day may be a study objective, but most people will not
know the answer to the question: “On average, how many liters of water does your
household use per person per day?” This information may be better collected by asking
a series of questions in order to determine the number of household members, the
number of trips each household member made to fetch water the previous day and and
the size of the container(s) used to fetch water.
4. Ensure logical flow of questions.Group questions about similar topics together. Organizing the survey into sections can
help facilitate this grouping.
5. Put sensitive questions later in the survey when participants’ comfort level will be greater.A question such as “The last time [name of youngest child] passed stools, what was
done to dispose of the stools?” should not be asked at the beginning of the survey.
29C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D 4 . P R I N C I P L E S O F M O N I T O R I N G F O R I M P R O V E M E N T
6. Avoid jargon in survey questionsSurvey questions are not an appropriate platform for WaSH jargon. Common everyday
language should be used to avoid confusion, and great care should be taken when
translating surveys to ensure that questions are achieving their desired meaning in the
local language and context.
7. Avoid constructs in survey questions.Constructs are ideas or theories considered to be subjective and not necessarily
universally familiar or based on observable reality. Examples of constructs in the
WaSH field include “productive uses of water,” or “opportunity cost,” etc. Asking
questions about these constructs is problematic because the concepts may be unfamiliar
to respondents, and therefore respondents may not be able to give meaningful answers
in relation to these constructs. Constructs may also contain implicit assumptions about
WaSH practices or human behavior, and these can likewise prove problematic if
unfounded. For these reasons, survey questions should rely on concepts that are directly
linked to observable reality wherever possible. Instead of asking about “productive uses
of water,” it may be better to ask about “water for gardens, crops or businesses,” etc.
Avoiding Bias in Survey Question Design
In all aspects of M&E, it is desirable to minimize bias and error. Error is defined as any
monitoring result that differs from the actual (“true”) result. Errors can be systematic or
random. Random errors are unpredictable errors that are equally likely to occur in either
direction. Systematic errors are more likely to occur in one direction than the other and
are often due to inadequacies in the measurement system. Bias is anything that introduces
systematic error in survey data. It is important to minimize when developing survey
questions. Several types of bias are relevant to survey development. Three of the most
common are recall bias, socially desirable response bias and acquiescence bias:
Recall bias occurs when respondents misreport events that happened a long
time ago. The best way to avoid recall bias is to ask questions about events that have
happened somewhat recently. For example, asking detailed questions about events
that happened in the past five years would likely result in poor quality data due to
recall bias. Asking about whether a water point has broken down in the past year or
even the past two weeks would likely result in much more accurate responses.
30 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
Socially desirable response bias occurs when respondents give false information to
avoid embarrassment or to impress the enumerator. Questions about sensitive topics such as open
defecation practices are more likely to provoke socially desirable response bias. Careful wording
of questions can help to eliminate this bias. Asking about open defecation practices with a question
that normalizes several different types of sanitation behavior may result in less bias. For example,
the question “Where do adults in this household defecate?” may produce more bias than this type of
wording: “Some people prefer to defecate in the bush or the open, some prefer to defecate in a latrine
or toilet and some prefer other places. What are the places that adults in this household defecate?”
It’s also important to consider the enumerator’s organizational affiliation with when attempting to
prevent socially desirable response bias. For example, if an NGO gives a safe water storage container
to a household, and then the same organization sends an enumerator to that household to ask “Is
your household using the safe water storage container?” then the respondent may be more likely to
say “yes” regardless of whether the household is using the container. In this case, socially desirable
response bias could be avoided by including a direct observation question in the survey so that the
enumerator observes whether the container is being used instead of (or in addition to) asking the
respondent.
Acquiescence bias can occur when a respondent is asked a leading question. Leading questions
tend to guide a respondent toward a given answer, causing the respondent to agree, even if this is not
accurate. “Do you always wash your hands before eating?” is a leading question. A better way to ask
about hand washing practices is “When do you usually wash your hands?” Acquiescence bias can be
avoided by developing balanced questions, rather than asking leading assertions for respondents to
disagree with or affirm.
The Importance of Operational Definitions
Operational definitions are clear and detailed definitions that relate to the variables being
measured. For example, many WaSH surveys may ask questions related to frequency of
diarrhea in children under the age of five. Each respondent may have a slightly different
definition of “diarrhea.” Including an operational definition in the survey question such as
“three or more loose or liquid stools within 24 hours” can help ensure consistency across
respondents. Operational definitions can be included in survey questions as “hints” or
“tips” listed next to survey questions or can be listed separately in an enumerator manual.
4.1 .6 . Data Collection: Best Practices and Pitfalls
Collecting M&E data fit-for-purpose in the field cannot occur unless adequate sampling,
survey tools and data collection methods are all in place. Even when these prerequisites
are present, however, M&E activities can fail catastrophically if data collection is not well
planned and managed in the field. In many cases, M&E efforts fail to produce
usable data, or to achieve their intended outcomes, due to one of the
following pitfalls:
31C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D 4 . P R I N C I P L E S O F M O N I T O R I N G F O R I M P R O V E M E N T
• Insufficient training of field staff
• Failure to adequately pretest, pilot and validate surveys and instruments
• Inadequate language skills of enumerators and/or inadequate translation of survey tools
• Inadequate collection and/or transport of water quality samples
• Inadequate supervision of field staff
• Lack of QA/QC procedures
Best Practices to Avoid Pitfalls
1. Ensure adequate length of training.Robust M&E activities capable of producing data fit-for-purpose can be quite involved,
requiring the ability to identify specified households, communities and facilities; conduct
structured surveys in a reproducible manner, employing a variety of precise operational
definitions and observation protocols; collect and process water quality samples; and accurately
complete and submit survey forms. Training new or existing staff to accurately perform all of
these tasks can be an intensive process (Figure 5). Enumerators can learn to collect data in
just one or two days but often require one or two weeks to learn to collect accurate data. After
the first day or two of training, many field staff are able to complete every question of a survey,
even if the responses are frequently inaccurate and do not reflect a good grasp of the applicable
LYNDA OLiViA reYFigure 5. A continuous quality improvement training workshop in Ghana.
32 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
protocols and operational definitions. A training period of one to two weeks or more
ensures that staff can effectively collect high-quality data while adhering to protocols,
correctly applying operational definitions and avoiding contaminating water quality
samples. If WaSH implementers are not carefully observing enumerators and the data
collected and are not performing systematic quality checks, it may be easy to conclude
that a few days’ training is sufficient. But given that the cost of training enumerators
may represent only 5-10% of the cost of all M&E activities for a given year and that
inadequate training of field staff can destroy 100% of the value of any data collected,
adequate training or even overtraining may be a worthwhile investment for many
WaSH implementers.
2. Pretest and pilot all survey instruments.While some WaSH implementers may use existing, validated survey instruments,
many prefer to create their own surveys and M&E tools or to contract a third party
to produce these tools. However, even when highly experienced WaSH profession-
als create such instruments, they inevitably develop some questions and methods that
simply do not work in the field. Pretesting and piloting these instruments before they
are deployed provides an opportunity to identify and correct such deficiencies. Failing
to do so virtually guarantees that some elements of the survey tools will not work as
intended. Frequently, the WaSH implementer may not know which elements these are
and thus cannot have confidence in any data obtained.
3. Confirm written translation and the language ability of field staff.In many contexts where WaSH M&E work is conducted, multiple local languages
may be spoken. Typically, M&E surveys and tools will be developed in one language,
such as English or French, and then translated into one or more local languages when
the tools are used in the field. This can either be done in written form, where with
tools are professionally translated in advance, or it can be done via translation-on-the-
fly, in which enumerators translate surveys to the local language while conducting
the survey. The former approach is preferable when the target language has a readily
understood written form; the latter may be necessary when such a written form does
not exist or is not widely known. In all cases, it is essential to confirm that any written
translations are correct, and that enumerators are truly able to speak the necessary
languages fluently. In many cases, enumerators may exaggerate their ability to speak
one or more of the necessary local languages. In some cases, they may count on their
ability to communicate in a different local language, which may serve as a lingua
franca in that local context. However, performing a survey in a language that is not
well understood by the respondent can compromise the validity of any data obtained.
33C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D 4 . P R I N C I P L E S O F M O N I T O R I N G F O R I M P R O V E M E N T
Thus, it is essential to confirm the accuracy of all written translations (often by back-
translation and/or third-party review) and to confirm the language abilities of all field
staff (often by an oral test with a native speaker of each required language).
4. Ensure proper technique in sampling procedures.Many WaSH implementers collect and analyze water quality samples (Figures 6a,
6b and 7). Often this is done through an external laboratory or consultant. In many
settings, it is common practice to use improvised containers for water quality sampling,
such as empty soft drink bottles that have been rinsed out. Similarly, in many cases
such samples are collected without particular attention to sterile technique (a method
of avoiding contamination during sample collection), cold chain and holding time
requirements (microbial samples) or sample preservation requirements (chemical
samples). Such oversights can compromise the validity of any water quality data
obtained. Thus, when conducting water quality testing, whether directly or through a
third party, it is essential to ensure that appropriate sampling procedures are observed.
5. Supervise field staff regularly.WaSH implementers typically attract highly professional and motivated staff.
However, without adequate supervision, field enumerators and/or survey consultants

can be prone to unintentional and intentional errors that can compromise data quality.
Common issues can include accidentally visiting the wrong communities, cutting
corners on water quality sample collection procedures to save time, neglecting proper
informed consent or failing to survey households or water sources that are far away due
to a reluctance to walk long distances. In extreme cases, enumerators or contractors
may even disregard random sampling designs (instead visiting communities or
households that are most convenient), or falsify data, fabricating surveys altogether.
While these problems may be rare, without adequate supervision they may not be
detected until it is too late, leading to wasted resources and loss of valuable M&E data.
Furthermore, if mistakes occur in only a small percentage of surveys or enumerators
but it is not known which are valid, the good data also will be compromised. To avoid
such issues, it is important to have regular supervision of field staff.
6. Implement consistent QA/QC procedures.In addition to supervision, structured QA/QC checks can quickly detect errors so that
they can be addressed and corrected. This is discussed in greater detail in section 4.1.8.

4.1 .6 . Selecting and Using Information and Communication Technologies
Information and communication technologies (ICTs) such as mobile survey tools (MSTs)
can dramatically improve the quality and efficiency of M&E data collection. Selecting
a suitable MST can enhance not only the field-level data collection process but also data
management and analysis. Some key MST functions include allowing users to gather and
transmit field data in real time, standardizing data storage and management, automating
routine analyses and visualizing data.32 A number of different MSTs are available on the
market, and this section offers some guidance on selecting and using an appropriate one.
When selecting an MST, different organizations may prioritize different factors.
Price may be the most important consideration for an organization with a small budget,
while usability may be the most important for an organization with little to no technology
experience. It could also be useful in the long term to consider selecting an MST that is
sufficiently well-established and will be available in years to come.
In a recent review,32 WI staff developed an
evaluation framework for testing MSTs. In order
to validate this framework, WI staff conducted
an illustrative evaluation of seven different
MSTs across five characteristics: relative cost,
performance, ease of use, learning curve and speed.
The seven reviewed MSTs were Akvo FLOW
(Akvo Foundation, Amsterdam), Open Data Kit
(ODK, open source), Magpi (Magpi, Washington,
DC), iFormbuilder (Zerion Software, Herndon, VA); Fulcrum (Spatial Networks, Inc.,
St. Petersburg, FL, USA), mWater (mWater, New York) and Survey CTO (Dobility,
Inc., Cambridge, MA, USA). Additional MSTs are available on the market, but the
illustrative evaluation was limited to these seven particular MSTs to limit the scope of the
validation exercise. The illustrative evaluation was performed in 2014-2015, and several
of the MSTs evaluated have been updated since. Results should be interpreted with this in
mind.
For each MST, both the application and the online dashboard were evaluated. Based
on five factors (cost, ease of use, performance, learning curve and speed), Fulcrum and
mWater received the best scores (i.e., lowest overall scores) at the time of the evaluation,
with Fulcrum performing best overall and mWater performing second-best overall
and best among the free MSTs evaluated (see Table 2 for more details). Fulcrum and
mWater were also rated the easiest to use, requiring the least amount of time to learn,

4.1 .7 . Hands-on Training
Hands-on training is an important aspect of ensuring high-quality data collection.
While training manuals and written protocols are helpful aids in training enumerators to
collect M&E data, these are not suitable substitutes for hands-on practice and in-person
training and observation (Figure 8). This supervised deliberate practice provides an
opportunity for enumerators to cement practical skills such as flow rate measurement,
water quality sampling and/or analysis, and sanitary inspections of water and/or sanitation
facilities. In addition, it provides an opportunity for enumerators to cement and calibrate
operational definitions of functionality, water source types and latrine types, and other
critical distinctions that tend to improve with hands-on practice. It is recommended that
such hands-on training be supervised by a staff member who is experienced in field data
collection and familiar with the surveys and tools being used. This can greatly improve
the quality of data collected and is often overlooked by WaSH implementers who may not
have firsthand experience of the impact of supervised hands-on training on M&E data
quality.

4.1 .8 . QA/QC and Reviewing Data
Systems for reviewing and verifying the quality and accuracy of field data collected
during M&E activities include the collection of QA/QC samples for water quality
analysis, including field blank and duplicate samples, as well as the use of photo
verification to enable supervisors to confirm data such as water source type and sanitation
facility type, etc. This can be done by supervisors using a structured QA/QC protocol
that systematizes the data review process. In some cases, simple checks can be performed
for all records (e.g., checking that IDs and community names are recorded correctly). In
other cases, QA/QC checks are more painstaking and should be performed for a random
subset of records (e.g., collecting field blanks and duplicates for 5-10% of water samples
or inspecting verification photos for a random 5-10% of water sources to verify source
type). These QA/QC checks enable WaSH implementers to rapidly catch and address
data quality problems related to issues that were not clearly explained in training or not
fully understood by some or all enumerators. Furthermore, they enable implementers to
detect quality control issues such as accidental contamination of water quality samples
during collection and storage. They also provide a safeguard against deliberate falsification
of M&E data, as QA/QC checks can be designed to detect most common types of
falsification, making such behavior prohibitively difficult for those very rare enumerators
or contractors who might consider it. Finally, data quality tends to improve when
enumerators and contractors know the data will be reviewed.
4.1 .9 . Regular Refresher Training
It is helpful to retrain data collectors on a regular basis to ensure that WaSH organizations
continue to collect high quality data and enumerators’ skill levels do not deteriorate. Up
to one week of refresher training each year is recommended. Retraining is most critical for
organizations that have experienced staff turnover, but even data collectors who have gone
through formal training in the past will benefit from refresher training. Although good
QA/QC protocols and time spent reviewing data go a long way in ensuring data quality,
refresher training helps to ensure that all data collectors are on the same page and keeps
their skill levels high and consistent.
Refresher training is an opportunity for enumerators to ask questions about parts of
the data collection process or specific survey questions that may be unclear. It is a good
opportunity to revisit key operational definitions to ensure consistency. Refresher training
should consist of a review of all survey questions and procedures for sanitary inspections,
water quality testing and other hands-on processes, with plenty of opportunities for data
collectors to ask questions or raise concerns. The refresher training should include a field

component (Figure 9) so that data collectors have an opportunity to practice under the
supervision of an instructor. Time should be set aside to debrief after each field practice
day so that data collectors have an opportunity to ask questions and the instructor can
address any issues that were observed.

4.1 .10. Proper Data Analysis
Achieving the SDGs will require more and better evidence from project, program,
subnational and national monitoring data, but at the moment these data are often
evaluated in a limited capacity. Making better use of monitoring data will require
improvements to data collection and analysis such as developing relevant and appropriate
survey questions, using standard definitions, ensuring data are reliable, analyzing data
40 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
using appropriate methods to find important relationships and using the results to generate
policy, programming, and practice recommendations. More efficient and effective service
delivery monitoring increases the potential for insight from studies using these data.
Clear, consistent language and standard definitions are needed to enable meaningful
comparison of data.33 In reports and publications, clearly reported methods that follow
appropriate reporting standards such as the STROBE statement or WHO reporting
guidelines for implementation and operational research allow others to replicate the data
collection or study in different settings or contexts.27, 34 In addition to standard definitions,
good practice reporting includes clear descriptions of the data, which allows other people
to use the data for future analysis and meta-analysis.
Understanding the determinants of improved service delivery is a challenge, as
service delivery is nested within complex social, political, technical and environmental
systems.35 Data analysis in the SDG era will require the use of different analysis
techniques—used in novel ways—to solve problems and develop improvement solutions.36
Harnessing the power of “big data” generated through remote sensing (e.g., satellite
imagery), systematic meta-analysis and other techniques will provide cost-effective ways
to incorporate additional determinants into service delivery analyses.37

4.3 .1 . Output Emphasis and Lack of Common Output Metrics
The improved source indicator was used to monitor the MDGs and it has been criticized
for inadequately representing water and sanitation safety, quality and level of service.
Much of local and national government and project and program monitoring, including
much of that done by CNHF partners, has focused on measuring outputs rather than
outcomes and services.

The WHO/UNICEF Joint Monitoring Programme (JMP) for Water Supply
and Sanitation, the organization responsible for monitoring water and sanitation,
has identified several important priorities in the SDG era: progressively eliminating
inequalities, achieving universal coverage of basic water and sanitation services, improving
sustainability, improving the levels of service so that water and sanitation services are
safely managed and improving water and sanitation in nonhousehold settings (e.g., schools
and health care facilities).1, 21, 38, 39

Water, sanitation and hygiene in health care facilities: status in low and middle income countries and way forward. Geneva.
4.3 .2 . Lack of Adequate Sampling and Sampling Size
As noted earlier, adequate sampling is critical to obtaining accurate M&E data in a cost-
effective manner. Some WaSH implementers explicitly conduct sampling as part of their
M&E activities, selecting a subset of communities or water sources to monitor, while
others may opt to monitor all communities in which they work and/or all water sources
they have constructed (typically such exhaustive monitoring of communities and/or
sources cannot be done every year for budgetary reasons). However, whether or not it is
recognized, virtually all WaSH programs that conduct monitoring at the household level
necessarily conduct sampling to identify a subset of households to survey, since it would
be virtually impossible to visit every household in each community to collect monitoring
data. In many cases, this household monitoring is not done via a robust random sampling
approach but is left up to the discretion of enumerators or staff in the field, who may
look around and select a given number of households in each community arbitrarily,
without using a robust randomization method. Such an approach tends to lead to
convenience sampling, rather than true random sampling; specifically, it may tend to bias
surveys towards households that are more centrally located and against households that
are inconvenient to survey due to location, the respondent’s primary language, absence
of a respondent on the first visit (WaSH MEL training manuals instruct enumerators
to return at least once more if no one is home on the first visit) or other factors. These
biases can tend to skew the results of monitoring data collected in important ways. For
example, households that are centrally located may tend to have greater access to water
and sanitation facilities, which may in turn influence the quantity and/or quality of water
the household consumes as well as their sanitation practices. Centrally located households
may also tend to be wealthier, which may influence a number of other variables and
outcomes of interest. Finally, if there is no documented method of identifying households,
46 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
it is difficult to assess the degree of bias that may be present in resulting data. These issues
are similarly applicable to programs that conduct convenience sampling when selecting
communities and/or water sources to monitor.
In addition, where sampling occurs (either via convenience or random sampling),
the sample size used can have a large impact on the results obtained. Many WaSH
implementers who conduct sampling at the community, facility and/or household
level may not perform sample size calculations when determining how large a sample
to monitor. Failure to use adequate sampling methods may result in
collecting too little data to answer key monitoring questions (e.g., how are
our programs performing and how can we improve them?) or to make meaningful
comparisons between program areas, time periods or treatment conditions (e.g., those
who have received intervention A vs. those who have not yet received it). Inadequate
sample sizes may also lead to false conclusions when making such comparisons
(e.g., a WaSH implementer may conclude that sanitation access is higher in Region A
than in Region B because the average coverage rates are higher for Region A, even if these
two values are not significantly different). Basing program changes on such a spurious
conclusion (e.g., shifting funding from one region to the other, or emulating program
elements from Region A), could thus lead to unintended consequences. It should also be
noted that, even with adequate sample sizes, comparisons over time can be problematic
because multiple factors other than program activities may affect outcomes of interest
(e.g., changes in climate, wealth, other demographic shifts, unrelated government
or NGO programs in the area). Unless these other potential confounding factors are
controlled for, changes in outcomes over time cannot be attributed to program changes or
activities and any such attributions may lead to false conclusions. These false conclusions
may be particularly problematic since short-term increases or decreases in measured
program performance may be attributed to recent programmatic changes, even if the
performance shifts are unrelated (due to confounding) or nonexistent (i.e., the shifts may
not be statistically significant if a small sample size was used). Thus, failure to conduct
adequate sampling and use an appropriate sample size can, at best, reduce the value and
quality of M&E data and, at worst, lead to false and/or misleading conclusions.
4.3 .3 . Lack of Adequate Monitoring Tools
Even with appropriate sampling methods, high-quality M&E data cannot be collected
without appropriate tools. Some WaSH implementers may conduct monitoring activities
using survey tools that do not contain properly designed questions (e.g., surveys may
include leading questions, confusing or double-barreled questions, questions with
problems due to recall bias or socially desirable response bias, or questions that respondents
47C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D 4 . P R I N C I P L E S O F M O N I T O R I N G F O R I M P R O V E M E N T
may not know the answers to). In other cases, questions may be adequately designed
but may not have adequate operational definitions and standards for the terms and
concepts they refer to. For example, without clear operational definitions of terms like
“functionality,” two enumerators may visit the same handpump that produces a low flow
after 20 pump strokes but may come to different conclusions about whether that source is
functional. Similarly, without precise operational definitions about what makes a latrine
accessible to those with limited mobility, inconsistent results may be obtained across
different enumerators and communities.
Finally, survey tools may have been adequately constructed, including adequate
operational definitions, but may not have been properly validated in the field. As a result,
survey questions may appear sound on paper, but in practice they may not produce
usable information in the local context due to issues with translations, culturally specific
constructs (e.g., the concepts of “water for productive uses” or “adequate water for
daily needs” may have very different meanings or no clear meaning in some contexts),
etc. Robust and validated tools will have addressed most of these issues so that the data
collected are far more likely to mean what WaSH implementers believe they mean.
However, while prior validation in one or multiple contexts improves the quality of
survey tools, it cannot guarantee that they will perform properly in a new context.
Piloting is always recommended. Nevertheless, the use of properly constructed survey
tools and operational definitions that have been validated in the field in one or more
countries can greatly improve the quality of M&E data.
4.3 .4 . Bias and Errors
Steps for minimizing the likelihood of bias and errors in survey questions are addressed
above, but bias can also be introduced during the design of M&E programs and survey
development phases. Sampling error deals with the precision of statistical estimates and
occurs when the sample is different from the population. Sampling bias occurs when the
sampling method favors the selection of some people over others. Convenience sampling is
a form of sampling bias. Careful sampling methods can reduce the likelihood
of sampling bias and errors. Training enumerators and other staff on the sampling
method and the importance of random sampling can help ensure that bias and error
prevention measures are respected.
Bias can also occur while the survey is being administered, for example, if the
enumerator attempts to answer the question for the respondent or if the enumerator asks
the respondent a leading question. Both can result in biased data, and it is important to
cover these possible sources of bias during the data collection training.
48 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
4.3 .5 . Absence of Quality Control
Although QA/QC is standard practice in most industries and in monitoring activities
conducted by many government agencies, such reviews are virtually nonexistent in the
WaSH sector. As a result, it is difficult or impossible to determine whether most WaSH
M&E data collected by WaSH implementers is credible. In the absence of adequate QA/
QC checks, such data should be interpreted with extreme caution, given the ease with
which bias and error can be introduced. While QA/QC checks do not need to be
elaborate or burdensome, their absence should be seen as a red flag with
respect to the credibility of M&E data and their introduction could greatly strengthen
most WaSH monitoring programs.
4.3 .6 . Problematic Assumptions
Operational research and evaluation of monitoring data are increasingly being discussed
by water and sanitation leaders as important methods of addressing water and sanitation
challenges and improving service delivery in lower middle income countries.21, 40, 41
Evidence generated from service delivery research can be used to help policymakers,
planners and practitioners make better decisions about how to manage infrastructure assets
and identify processes that lead to better service provision.
The many problems with data collection and the quality of water and service delivery
research studies are well documented.26, 42 Problems include data collected without a
clear objective or purpose, the use of poorly designed survey questions, and the use of
inadequate methods or inadequately documented methods. Data analysis may be limited
to descriptive statistics, with modeling methods infrequently used to examine relationships
between service outcomes and determinants.42 Results of service delivery studies are
infrequently published in peer-reviewed journals or translated into policy and practice
recommendations.26
Inadequate data collection and limited analysis of data wastes limited resources
and makes it difficult for decision makers to understand and synthesize evidence.
While improvements are desirable, a systematic approach has not previously been taken
to characterize the problems and challenges affecting service delivery data collection
Inadequate data collection and limited analysis of data wastes limited resources and makes it difficult for decision makers to understand and synthesize evidence.

Studies on water and sanitation service delivery reveal a number of important policy
and practice findings, but they also have important methodological limitations. In some
studies, some survey questions could have been improved or modified to reveal greater
insight. For example, in three studies, data were removed from analysis due to concerns
about the reliability of survey questions.3, 22, 43 In these studies, researchers were not
involved in the design of the data collection instrument, design of the survey questions or
the data collection. In other examples, ethics approval was not reported, and in some cases,
data collection methods were not reported.44, 45 Data limitations and sources of bias were
often not documented.44, 45 Data sets were often not publicly available for further analysis
or meta-analysis.44 •

While there is considerable interest in WaSH monitoring and evaluation, collecting M&E
data for the purpose of reporting and publicity adds little value to the end users of WaSH
services. In contrast, the use of high-quality, fit-for-purpose data to drive improvements
in the quality and sustainability of WaSH programs can have a dramatic impact on the
lives of the populations those programs serve. Prior to the MDG period, it was common
for WaSH implementers to complete water and sanitation projects with little in the way
of monitoring and reporting of outcomes. In recent decades, routine M&E of WaSH
programs has become much more widespread, but the resulting reports often languish on
shelves and hard drives without prompting substantive action to learn from their findings
and leverage these learnings for improvement. Achieving the ambitious new water and
sanitation goals laid out by the SDGs will require WaSH implementers of all varieties to

improve the quality and efficiency of their programs and activities. Leveraging fit-for-
purpose WaSH M&E data to drive this improvement through systematic implementation
science methods may be one highly effective approach.

One of the most important shifts needed for such evidence-based improvement to
occur is the proliferation of an improvement mindset among WaSH implementers and
practitioners. Currently, many WaSH implementing organizations, including nonprofit
organizations, bilateral aid organizations and national government agencies and ministries,
tend to view WaSH implementation through an output-based lens. Specifically, many
implementers perceive the need to deliver WaSH services but tend to view this task as a
process of converting unserved populations to served populations through the delivery
of a fixed suite of interventions. The idea of using M&E data to modify and improve
service delivery processes in order to achieve better outcomes is alien to many WaSH
implementers. However, when these ideas are presented and evidence-based quality
improvement tools are made available, implementers seem eager to embrace them,
provided it does not interfere with meeting existing output-driven deadlines. Thus, before
the quality and efficiency of WaSH service delivery can be improved, a mindset shift
may be required among WaSH implementers, specifically, a shift from focusing on
outputs to one that includes in addition to outcomes the empowerment
of implementers at all levels to modify and improve the processes
through which they deliver WaSH services. These mindset shifts, accompanied
by the availability of suitable WaSH quality improvement tools and methods, have the
power to considerably improve quality and efficiency in WaSH service delivery.

Implementation science (IS) methods such as CQI are predicated on the core assumptions
that all work is made up of processes and every process can be improved. As an example,
even a task as simple as making tea follows a defined process: water must be collected and
boiled, then tea must be retrieved and placed in a cup or pot. The hot water must then
be added to the tea. This mixture must be allowed to steep for a defined period of time
or until a desired strength of tea is achieved. While “making tea” may seem like a single
action—one often performed automatically—it is actually a process with multiple defined
steps. To improve the process, the individual steps can be studied to determine which is
the slowest, the most costly or the most prone to errors, and attention can be focused there.

While the application of these core assumptions to something as mundane as brewing
tea may seem trivial, these principles are equally applicable to a wide variety of processes
across virtually every sector of the global economy. Implementation science methods such
as LEAN, Six Sigma, total quality improvement, continuous quality improvement and
others have been used to revolutionize sectors as diverse as manufacturing,12 customer
service,13 health care,14 finance15 and others. These IS methods have differences but are
broadly similar in their functions; in all cases, the IS process involves clearly defining a
specific problem to be solved or opportunity to be seized, collecting and analyzing relevant
data, and using the findings from that analysis to conceive and implement improvements.
This cycle, in its most general form, has been described as the “Plan, Do, Study, Act,”
or PDSA cycle. Extensive evidence demonstrates the effectiveness of these methods in
improving processes and outcomes across each sector in which they have been applied.12-15
Implementation science methods are most suitable for solving complex process
problems in which a process that already achieves a desired outcome is to be improved.
Complex problems are defined as those for which an effective solution is not yet known
and is not intuitively obvious to those tasked with solving the problem. Examples
of complex problems include improving fuel economy in compact passenger cars or
reducing the waiting time in a hospital’s urgent care clinic. Each team member may have
preconceived ideas of how best to solve this problem, but it is not necessarily intuitively
obvious that any one idea will work, let alone which (if any) will be most effective. By
contrast, a problem that is not complex is one that has a known or obvious solution that
has not been implemented for some reason other than lack of knowledge about what to
do. Examples of noncomplex problems include a flat tire on a passenger car or a broken
elevator in an urgent care clinic. Furthermore, IS methods are generally better suited for
improving the quality or efficiency of a process rather than increasing the extent to which
that process is implemented or the level of investment in its implementation. For example,
IS methods are well suited for reducing the failure rate of water systems or the cost of
such systems but are less well suited for increasing the number of systems a government
or implementer chooses to implement. While these methods may not be universally
applicable to all problems, however, IS methods remain powerful tools for improvement
in a wide variety of complex systems across virtually all sectors.

• Do the monitoring

• Act to make an improvement based on the findings
5.3 .1 . Suitability of CQI for Addressing Complex WaSH Problems
Given the strength of IS methods such as CQI for solving complex problems, it seems
logical to apply these approaches to the complex challenges facing WaSH implementers
as they prepare to meet the ambitious targets laid out by SDG 6. Specifically, adapting
WaSH programs to improve the safety and reliability of water supplies are complex
52 M E LW a S H C O M P E N D I U M O F B E S T P R A C T I C E S A N D L E S S O N S L E A R N E D
problems without obvious or known solutions; doing so in a cost-effective manner will
be a priority for many implementers seeking to serve ever-increasing populations with
limited resources. Likewise, enhancing the quality of sanitation and hygiene services
and increasing sanitation and hygiene uptake are complex problems that may benefit
from systems thinking and CQI methods. The collection and analysis of high-quality
fit-for-purpose data may reveal the root causes of problems in these areas or highlight
opportunities to capture greater efficiencies.
5.3 .2 . Adaptation of CQI Methods to WaSH
WaSH programs have many similarities to manufacturing, service industries and
health care, which suggests IS methods could be applied to many WaSH challenges.
Specifically, WaSH programs typically use defined implementation processes. For
example, government and nonprofit implementers who install water supply technologies
such as boreholes and piped schemes will typically execute defined planning, siting,
implementation, commissioning and training activities in a reproducible process;
management and maintenance of these systems depend on additional defined processes.46
These processes rely on implicit or explicit standard operating procedures and are therefore
suitable for systematic quality improvement. Similarly, many WaSH implementers will
conduct sanitation interventions using standardized methods such as community-led total
sanitation, which also has a defined and standardized process that is open for adaptation
and improvement.47
Furthermore, like medicine, WaSH programs are designed to produce measurable
outcomes, including changes in health and wellbeing, in addition to satisfaction and
changes in other proxy variables (such as access to water and sanitation services,
water quality and water quantity), which may be easier to measure and more rapidly
sensitive to system improvements than changes in underlying health status and
livelihood outcomes. Unlike manufacturing and hospital-based medicine, most WaSH
programs are implemented in diverse and decentralized community settings rather
than centralized, controlled industrial or clinical environments. However, successful
examples of quality improvement methods in community-based medicine48 suggest that
community-based or community-managed WaSH programs may be similarly suitable
for systematic improvement. Furthermore, many WaSH programs, particularly those
related to sanitation and hygiene, require behavior change on the part of the end user
to be successful; likewise, behavior change is a component of some successful quality
improvement projects in health care as well.49

5 .3 .3 . Implementing CQI in WaSH Programs
The justification for the application of quality improvements methods to challenges
in the WaSH sector is ample. Despite many similarities, however, direct translation
of quality improvement methods from other sectors is not appropriate. Some unique
aspects of WaSH require adaptation of conventional quality improvement methods. For
example, while many water and sanitation interventions in urban areas may be managed
by municipal or private utility companies, community management of rural water and
sanitation systems is common in many lower middle income countries and presents
unique features and challenges with respect to implementing improvement projects.
Furthermore, the challenges of data collection in WaSH contexts may be much greater
than in clinical and industrial contexts, where trained clinicians and workers may be
readily available to collect data with minimal disruption to their ongoing activities. In the
case of WaSH CQI, the implementers driving improvement activities may be separated
from the communities and systems they wish to measure by greater magnitudes of time
and space, particularly where improvements in post-implementation outcomes of rural
WaSH programs are desired. This separation in time and space requires creative solutions
to collect timely, high-quality data in a focused and cost-effective manner.
Initial applications of CQI methods to WaSH programs have been undertaken in
West Africa with promising results. In Ghana, a CQI project demonstrated improvements
in household water quality and promising signs of improvements in water source
functionality. In Burkina Faso, safe water storage innovations from Ghana are being
adapted to the Burkinabe context with promising initial results. In Niger and Mali,
programs are underway to conduct CQI projects focusing on household water quality as
well, while in Ghana the next round of CQI is underway to identify opportunities for
improving sanitation outcomes in rural communities. In all cases, novel implementation
challenges have been identified and addressed. Thus, this work is not only building
an evidence base for the value of IS and CQI methods in WaSH, but also addressing
methodological questions as part of the process of establishing best practices in WaSH
CQI. Based on current activities and results, it seems likely that implementation science
methods may play a valuable role in improving service quality and contributing to the
achievement of WaSH-related SDGs. •
