Overview
Remolha wastewater treatment plant serves Santa Maria da Feira, Portugal, treating wastewater for approximately 4,800 people with secondary treatment. The plant discharges 800.31 m³/day and is located within 10 km of the coast.
Remolha is a wastewater treatment plant located in Santa Maria da Feira, in the Aveiro district of Portugal. It serves a population of approximately 4,800 people, making it a small to medium-sized facility within the country's wastewater infrastructure. The plant is situated near the coast, less than 10 kilometers from the Atlantic Ocean. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids. The plant has a designed capacity of 8,874 m³/day and currently discharges an average of 800.31 m³/day of treated effluent. The treated wastewater from Remolha is discharged into local watercourses that eventually flow into the Atlantic Ocean. The coastal environment in this region supports diverse marine life and is important for local fisheries and tourism. Proper treatment helps protect the water quality of the receiving waters and the broader coastal ecosystem.
Environmental context
The plant discharges into local streams that drain into the Atlantic Ocean near the coast of Aveiro. The coastal waters in this region are ecologically sensitive, supporting diverse marine life including fish, crustaceans, and seabirds. The Ria de Aveiro lagoon system, a nearby coastal lagoon, is an important habitat for migratory birds and aquatic species. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain water quality in these productive coastal ecosystems.
