Overview
Matosinhos wastewater treatment plant serves 287,000 people in Portugal. Located near the coast, it operates under EU Urban Waste Water Treatment Directive standards.
Matosinhos wastewater treatment plant is a major municipal facility in Portugal, serving a population of approximately 287,000. The plant is situated near the Atlantic coast, reflecting the region's urban and industrial character. As a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC), the plant is required to provide secondary treatment as a minimum, with tertiary treatment likely in place to protect sensitive coastal waters. The designed capacity is 1.00 (likely in cubic meters per day or similar unit), indicating a substantial infrastructure investment. The plant discharges treated effluent into the Atlantic Ocean via the coastal environment. This discharge supports the ecological health of the surrounding marine area, which is important for local fisheries and tourism. The plant's operation is critical for maintaining water quality in the region's coastal zone.
Environmental context
The plant discharges into the Atlantic Ocean along Portugal's northwest coast. This coastal area supports diverse marine life, including fish and seabird populations, and is an important recreational and economic resource. The treated effluent must meet stringent quality standards to minimize nutrient loading and protect the sensitive coastal ecosystem from eutrophication.
