Benedita Wastewater Treatment Plant, Alcobaça, Portugal

The Benedita wastewater treatment plant is located in Pedra Redonda, Benedita, in the municipality of Alcobaça, Leiria district, Portugal. It serves a population of approximately 8,600, classifying it as a medium agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by local authorities. As a plant serving between 2,000 and 10,000 people, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment as a minimum standard. The designed capacity is 1.00 (likely in thousands of cubic meters per day or similar), indicating the plant's scale. The regulatory framework ensures appropriate treatment levels for the receiving environment. The plant discharges treated wastewater into local watercourses that eventually drain into the Atlantic Ocean via the Tagus River basin or nearby coastal systems. The region's hydrology supports agricultural and ecological uses downstream, and the plant's operation helps protect water quality in the area.

The Benedita plant is located in the Tagus River basin, which drains into the Atlantic Ocean near Lisbon. The local watershed supports agricultural activities and diverse aquatic habitats. Downstream water bodies include small streams that feed into the Tagus estuary, an ecologically important area for migratory birds and fish species. The plant's discharge contributes to maintaining water quality in this sensitive riverine and estuarine environment.
