ELASSONA Wastewater Treatment Plant, Elassona, Thessaly, Greece

The ELASSONA wastewater treatment plant is located in the municipality of Elassona, within the Larissa regional unit of Thessaly, Greece. The facility serves a population of approximately 8,144 residents, making it a medium-sized agglomeration under Greek and EU classification. It plays a key role in managing municipal wastewater for this inland community. As a Greek plant, ELASSONA 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 appropriate treatment before discharge into inland waters. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating it is sized to handle the community's wastewater flows. The treated effluent is discharged into a local watercourse that eventually drains into the Aegean Sea via the Pineios River basin. This river system supports diverse aquatic life and is important for regional agriculture and biodiversity. The plant's operation helps maintain water quality in the downstream environment.

The plant discharges into a tributary of the Pineios River, which flows through the Thessalian plain and empties into the Thermaic Gulf of the Aegean Sea. The Pineios basin supports irrigated agriculture and provides habitat for freshwater species. Effective treatment at ELASSONA helps prevent nutrient pollution and protects the ecological health of this important river system.
