Overview
Reguengos de Monsaraz wastewater treatment plant serves 8,600 people in Évora, Portugal. It operates under EU Urban Waste Water Treatment Directive standards for small agglomerations.
The Reguengos de Monsaraz wastewater treatment plant is located in the town of Reguengos de Monsaraz, in the Évora district of southern Portugal. It serves a population of approximately 8,600 residents, classifying it as a small agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the municipal wastewater infrastructure for the region. As a small agglomeration in Portugal, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into freshwater bodies. For populations under 10,000, secondary treatment is typically mandated unless the receiving waters are designated as sensitive areas, which may require more advanced treatment. It is expected to comply with national and EU standards. The treated effluent is discharged into local watercourses that ultimately drain into the Guadiana River basin, which flows south to the Gulf of Cádiz in the Atlantic Ocean. The Guadiana River supports diverse aquatic life and is an important ecological corridor in the Iberian Peninsula. The plant's operations help protect the water quality of this river system and downstream environments.
Environmental context
The plant discharges into the Guadiana River basin, which flows through Portugal and Spain before reaching the Gulf of Cádiz in the Atlantic Ocean. The Guadiana River supports a variety of fish species and provides habitat for migratory birds. The region's Mediterranean climate with hot, dry summers and mild, wet winters influences water availability and treatment needs. Protecting the river's water quality is essential for downstream ecosystems, including the Guadiana estuary, which is an important nursery area for marine life.
