The Psyttalia WWTP includes pre-treatment, primary and secondary treatment with biological nitrogen removal, sludge treatment and cogeneration of electrical and heat. The Psyttalia WWTP capacity is 5,600,000 p.e., being one of the biggest WWTPs in Europe and worldwide. The average supply of incoming wastewater is the range of 730, 000 m3/day. The first phase of the project has been in operation since 1994, the second phase since 2004, while the third and final phase of works completed in 2007 with the construction of sludge thermal drying unit. EYDAP undertook the construction and operation of the project "Main Collectors and Wastewater Treatment and Disposal in Thriassio Pedio", which is a sensitive environmentally area. The aim was to upgrade the quality of life of 117,000 inhabitants, restoring the balance of the ecosystem of the sea of Eleusis and generally contributing to the sustainable development of the region.
