The Psyttalia Wastewater Treatment Plant (WWTP) stands as a cornerstone of Greece’s environmental infrastructure and ranks among the largest and most advanced facilities of its kind in Europe. Serving a population equivalent of 5,600,000, with a staggering treatment capacity of 1,000,000 cubic meters per day, the plant is the primary guardian of the Saronikos Gulf, fundamentally transforming the ecological health of the Attica region.
NAMA played a pivotal role in the evolution of this monumental project, undertaking the comprehensive design and construction supervision of Phase B. This phase was critical for the plant’s transition to full secondary biological treatment and advanced sludge management, ensuring compliance with the most stringent European environmental directives.
Multidisciplinary Excellence
The project's immense scale demanded a holistic engineering approach. NAMA’s involvement spanned the entire technical spectrum:
- Hydraulic and Environmental Engineering: Optimizing the vast flow networks and biological processes to ensure high-quality discharge into the marine ecosystem.
- Structural and Geotechnical Design: Engineering robust structures capable of withstanding the unique coastal and seismic conditions of Psyttalia island.
- Electromechanical Systems: Integrating sophisticated automation and energy-intensive systems for seamless 24/7 operations.
- Topographic and Geospatial Support: Precision mapping of the island's complex terrain to facilitate large-scale industrial expansion.
A Legacy of Sustainability
Beyond technical metrics, Psyttalia represents a triumph in circular economy and sustainability. The facility utilizes advanced anaerobic digestion to produce biogas, significantly offsetting its energy footprint, while the treated effluent has led to the remarkable revitalization of the Saronikos marine life.
For NAMA, Psyttalia is more than a project; it is a testament to our ability to manage nationally significant infrastructure that balances industrial necessity with profound environmental stewardship.
