Overview
S Joao das Lampas wastewater treatment plant serves 6,300 people in São João das Lampas, Sintra, Portugal. Located near the Atlantic coast, it operates under EU Urban Waste Water Treatment Directive standards.
S Joao das Lampas wastewater treatment plant is located in Catribana, São João das Lampas, within the municipality of Sintra in the Lisbon district of Portugal. The facility serves a population of approximately 6,300 residents, classifying it as a small to medium agglomeration under EU classification. Its coastal proximity places it within a sensitive area requiring appropriate treatment to protect marine ecosystems. As a Portuguese plant, S Joao das Lampas operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. For plants in coastal areas, the directive may require more advanced treatment if the discharge affects sensitive environments. The designed capacity is 1.00 (likely in thousands of cubic meters per day), indicating a modest facility scaled to local needs. The plant's treated effluent ultimately drains into the Atlantic Ocean via local watercourses. The coastal environment supports diverse marine life and is part of the broader Lisbon coastal ecosystem. Proper treatment is essential to prevent nutrient loading and protect water quality in this ecologically sensitive region.
Environmental context
The plant discharges into local streams that flow to the Atlantic Ocean near the Sintra coast. This coastal area supports diverse marine habitats and is important for local fisheries and tourism. The proximity to the ocean means that treated effluent must meet strict quality standards to avoid eutrophication and protect sensitive coastal ecosystems.
