Overview
S Jacinto secondary treatment plant serves 3,150 people in coastal Portugal, discharging 525.20 volume units. It operates under EU Urban Waste Water Treatment Directive standards for small agglomerations.
S Jacinto is a wastewater treatment plant located in coastal Portugal, serving a population of approximately 3,150. The facility provides secondary treatment, a standard level for small agglomerations under EU regulations. Its designed capacity is 9,377.00 volume units, with a current discharge volume of 525.20. As a secondary treatment plant, S Jacinto meets the minimum requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 10,000 population equivalent. The directive mandates secondary treatment for all inland discharges, with more stringent requirements for sensitive areas. The plant's capacity utilization appears low, suggesting it may be designed for future growth or seasonal peaks. The plant is situated within 10 km of the Atlantic coast, discharging treated effluent into the coastal environment. The local watershed drains into the Atlantic Ocean, supporting diverse marine ecosystems. The plant's location near the coast necessitates careful management to protect coastal water quality and marine life.
Environmental context
The plant discharges into the Atlantic Ocean along Portugal's western coast. This coastal region supports diverse marine habitats, including rocky shores and sandy bottoms, and is part of the broader Iberian coastal upwelling system, which sustains rich fisheries. The treated effluent must comply with EU standards to minimize nutrient loading and protect coastal water quality.
