Overview
The Tripoli wastewater treatment plant serves the municipality of Tripoli in the Peloponnese region of Greece. It treats wastewater from approximately 43,766 people under the EU Urban Waste Water Treatment Directive.
The Tripoli wastewater treatment plant is located in the industrial area of Tripoli, within the Municipality of Tripoli in Arcadia, Peloponnese, Greece. It serves a population of approximately 43,766, classifying it as a medium agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and treats municipal wastewater from the city and surrounding communities. 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 directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to meet these EU standards to protect local water quality. The treated effluent is discharged into local watercourses that drain into the Alfeios River basin, which flows westward into the Ionian Sea. The plant plays a key role in safeguarding the region's water resources, supporting both ecological health and downstream uses such as agriculture and recreation.
Environmental context
The Tripoli plant discharges into streams that feed the Alfeios River, one of the longest rivers in the Peloponnese, which flows into the Ionian Sea. The river supports diverse aquatic life and is important for irrigation in the region. The plant's operation helps prevent nutrient pollution and protects the ecological balance of the downstream watershed.
