Overview
Foz do Arelho wastewater treatment plant serves 7,000 people in Portugal. Located near the coast, it operates under EU Urban Waste Water Treatment Directive standards.
Foz do Arelho wastewater treatment plant is a municipal facility serving approximately 7,000 people in Portugal. The plant is situated near the Atlantic coast, reflecting the region's coastal character. As a small agglomeration, it plays a key role in managing local wastewater and protecting the surrounding environment. The plant's designed capacity is 1.00 (likely in thousands of cubic meters per day or similar unit). Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide secondary treatment or equivalent. It is expected to comply with national and EU standards for wastewater treatment. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean. The coastal location means the plant's discharge can affect marine water quality and nearby ecosystems. Proper treatment is essential to protect bathing waters and marine life along the Portuguese coast.
Environmental context
The plant discharges into a coastal watershed that flows into the Atlantic Ocean. The area supports diverse marine and coastal habitats, including sandy beaches and rocky shores. The receiving waters are ecologically sensitive, supporting fish, shellfish, and migratory bird species. Maintaining high treatment standards is crucial to prevent nutrient enrichment and protect water quality for recreation and biodiversity.
