Technical Visit: Psyttalia Wastewater Treatment Plant

As part of the RETASTE Conference program, participants are invited to join a technical visit to the Psyttalia Wastewater Treatment Plant (WWTP), a flagship project of environmental engineering and circular economy in action.

Located on Psyttalia Island in the Saronic Gulf, this facility treats the wastewater of over 5.6 million people in the greater Athens area, making it one of the largest WWTPs in Europe and globally. It showcases a complete and state-of-the-art treatment system that includes:

Pre-treatment at Akrokeramos and transfer via submerged pipelines
Primary and secondary biological treatment with advanced nitrogen removal
Sludge digestion, dehydration, and thermal drying
Cogeneration of electrical and thermal energy from sludge
Final discharge of treated effluent with reduced environmental impact
This visit offers a unique opportunity to gain insights into sustainable urban water management, resource recovery, and energy-efficient treatment processes. With a strong focus on environmental protection, Psyttalia WWTP stands as a model of integrated wastewater management and innovation.

🚌 Transportation and light lunch is free for all Full Delegates.
