Psitalia island

Before the battle of Salamis in 480 BC, the Persians settled on the island Persian guard, composed of warriors and nobles. After the battle, the Persian fleet leaving to Faliro left the guard of Psyttalia and Aristides landed on the island and killed all Persians. Therefore one of the trophies after winning, was set up on Psyttalia island. It is commemorated by Aeschylus, Herodotus, Plutarch, Strabo, Pausanias and other authors as a place of worship of Pan,

Location

Since the 50s, people began to use homemade cesspools and carry sewage by tankers to ease recipients, which could meet with the needs of Athens. In 1959, therefore, they began to build the central drain, leading the effluent of the historic center in Akrokeramos, in Keratsini area, and pouring them into the sea until 1994. The pipeline created environmental problems , thereby contaminating the Saronic Gulf and the coastal region of Elefsina.

Greece during that time was developing economically and as a member of the EEC (European Economic Community) has obtained the legal obligation to protect its sea environment. The most important legal document for the effluent, was Directive 91/271 / EEC, requiring at least secondary wastewater treatment for all agglomerations of more than 15,000 inhabitants, up to the end of 2000. Athens in 1985, with the operation of the Wastewater and sewage Metamorphosis Centre, managed to close the numerous "cesspool" that were scattered in the Attica basin. There was no national experience on this, so people reacted strongly.

And like this, they started to build the Supplemental Sewerage Pipeline, to transport waste water from the rest of Athens in Akrokeramo and undersea pipelines of wastewater after pretreatment, from Akrokeramo to Psyttalia, the mainly treatment projects on the island and two underwater outfall pipes 1,870 meters each for the disposal of the already treated wastewater to the Saronic Gulf, at a depth of 63 meters. This project was very complicated, but it would be one of the largest in K.E.L extent, on Earth, after covering almost all the area throughout the island
