Pyrgos Wastewater Treatment Plant - Serving Pyrgos Municipality, Greece

The Pyrgos wastewater treatment plant is located in the Municipality of Pyrgos, in the regional unit of Elis, Western Greece. It serves a population of approximately 25,000 people, classifying it as a medium-sized agglomeration under EU regulations. The plant is situated near the Ionian Sea coast, within 50 km of the shoreline, and plays a key role in protecting the local marine environment. As a Greek facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The designed capacity is 1.00 (likely in cubic meters per day or similar units), indicating the infrastructure is scaled to handle the incoming load. The regulatory framework ensures compliance with discharge standards for organic matter and nutrients. The treated effluent is discharged into the local watershed, which ultimately drains into the Ionian Sea. This coastal region supports diverse marine life and is important for fisheries and tourism. Proper treatment helps prevent eutrophication and protects the ecological balance of the coastal waters.

The plant discharges into the Ionian Sea via local watercourses. The Ionian Sea is a deep, oligotrophic basin that supports diverse marine ecosystems, including seagrass meadows and important fish nursery areas. The region's coastal waters are sensitive to nutrient inputs, making effective wastewater treatment critical for preventing algal blooms and maintaining water quality for tourism and fisheries.
