Overview
Kalamata wastewater treatment plant serves the municipality of Kalamata in the Peloponnese region, Greece. It treats wastewater for approximately 92,000 people, supporting the local urban population.
The Kalamata wastewater treatment plant is located in the municipality of Kalamata, within the Peloponnese region of Greece. It serves a population of approximately 92,000 people, making it a medium-to-large agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). The plant is situated near the coast, within 50 km of the Mediterranean Sea, and plays a key role in protecting the local marine environment. As a Greek facility, the plant operates under the EU UWWTD (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the discharge enters sensitive areas. The plant's designed capacity is 1. The regulatory framework ensures that the plant meets European standards for wastewater treatment. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Messinian Gulf of the Ionian Sea. This coastal area supports diverse marine life and is important for local fisheries and tourism. The plant's operation helps reduce nutrient and pollutant loads, safeguarding the ecological health of the gulf and the broader Mediterranean Sea.
Environmental context
The plant discharges into the Messinian Gulf, part of the Ionian Sea, which is a semi-enclosed basin with limited water exchange. The gulf supports important marine habitats, including seagrass meadows and nursery grounds for fish species. Nutrient inputs from wastewater can contribute to eutrophication, so the plant's treatment performance is critical for maintaining water quality and biodiversity in this coastal ecosystem.
