Overview
YANNOULI wastewater treatment plant serves the community of Giannouli in Thessaly, Greece. It operates under the EU Urban Waste Water Treatment Directive, which sets treatment standards for agglomerations of this size.
The YANNOULI wastewater treatment plant is located in the Giannouli municipal unit, part of the Larissa municipality in the Thessaly region of Greece. Serving a population of approximately 4,620, it is classified as a small agglomeration under Greek and EU regulations. As a Greek facility, the plant operates within the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges into freshwater and estuaries from agglomerations of this scale. The designed capacity is 1.00 (likely in thousand cubic meters per day or similar unit), indicating a modest infrastructure suited to the local population. The plant's treated effluent ultimately drains into the broader Thessaly watershed, which flows into the Aegean Sea. The region's water bodies support agricultural irrigation and local ecosystems, making proper treatment essential for protecting downstream water quality and aquatic life.
Environmental context
The YANNOULI plant discharges into the Thessaly basin, which drains into the Aegean Sea via the Pineios River and its tributaries. This watershed supports agricultural activities and diverse aquatic habitats. Proper wastewater treatment is critical to prevent nutrient enrichment and protect the ecological balance of the downstream marine environment.
