Vila Nova de Cerveira Wastewater Treatment Plant - Advanced Treatment in Northern Portugal

Vila Nova de Cerveira wastewater treatment plant is located in the town of Vila Nova de Cerveira, in the Viana do Castelo district of northern Portugal. The plant serves a population of approximately 3,800 residents and operates with advanced treatment technology, ensuring high-quality effluent before discharge. As a facility in Portugal, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires appropriate treatment for agglomerations of this size. The plant's designed capacity is 6,500 m³/day, and it currently treats an average daily flow of 633.58 m³, indicating ample capacity for future growth. The treated wastewater is discharged into the local environment near the Minho River, which forms the border between Portugal and Spain and flows into the Atlantic Ocean. The plant's proximity to the coast (within 10 km) and the ecologically sensitive Minho estuary underscores the importance of its advanced treatment in protecting coastal and marine water quality.

The plant discharges into the Minho River basin, which drains into the Atlantic Ocean via the Minho estuary. This estuary is an ecologically important area that supports diverse aquatic life, including migratory fish species. The advanced treatment at the plant helps reduce nutrient and pollutant loads, protecting the estuary's water quality and the downstream coastal environment from eutrophication and other impacts.
