Overview
Serzedelo II is a wastewater treatment plant serving 180,500 people in Vila Nova de Famalicão, Portugal. It operates under the EU Urban Waste Water Treatment Directive, which mandates advanced treatment for large agglomerations.
Serzedelo II is a wastewater treatment plant located in Vila Nova de Famalicão, in the Braga district of northern Portugal. It serves a population of approximately 180,500 people, classifying it as a large agglomeration under EU regulations. The plant is situated inland, away from the coast, and its operations are integrated into the region's water management infrastructure. As a large-scale facility, Serzedelo II is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires tertiary treatment for agglomerations over 150,000 population equivalent in sensitive areas. The plant's capacity is designed to handle 1.00 unit of volume, indicating it is equipped to manage the wastewater load from the served population. The regulatory framework ensures that the plant meets stringent effluent quality standards to protect receiving waters. The treated wastewater from Serzedelo II is discharged into local water bodies that ultimately drain into the Atlantic Ocean via the Douro River basin or nearby coastal systems. The plant plays a critical role in safeguarding the water quality of the region's rivers and streams, supporting aquatic ecosystems and downstream communities. Its operation contributes to the environmental health of the broader watershed, which includes agricultural and urban areas.
Environmental context
Serzedelo II discharges treated wastewater into local watercourses that flow into the Douro River basin, one of the major river systems in the Iberian Peninsula, which empties into the Atlantic Ocean near Porto. The downstream environment supports diverse aquatic life and is important for regional biodiversity. The plant's compliance with EU directives helps mitigate nutrient pollution and protects sensitive estuarine and coastal habitats from eutrophication.
