Overview
Troia wastewater treatment plant serves the Grândola area in Portugal. Located near the coast, it is designed for a capacity of 1.00 unit and serves a population of 6,500.
The Troia wastewater treatment plant is situated in the Carvalhal area of Grândola, in the Setúbal district of Portugal. It serves a population of approximately 6,500 people, placing it in the small agglomeration category under EU classification. The plant's location near the Atlantic coast influences its operational and environmental context. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like Troia are required to provide appropriate treatment to protect receiving waters. The plant's design capacity of 1.00 unit suggests it is sized to handle the local wastewater load. The regulatory framework ensures that discharges meet standards for coastal areas. The treated effluent from the plant likely discharges into the Atlantic Ocean or a nearby coastal water body, given its proximity to the coast. The surrounding region includes the Sado Estuary and Arrábida Natural Park, which are ecologically sensitive areas supporting diverse marine life and migratory birds. Proper wastewater treatment is essential to maintain water quality in these habitats.
Environmental context
The Troia plant is located near the Atlantic coast of Portugal, within the Sado River basin. The receiving waters ultimately drain into the Atlantic Ocean, which supports rich marine biodiversity, including dolphins and migratory fish. The nearby Sado Estuary is an important wetland for bird species. Effective wastewater treatment helps protect these coastal and estuarine ecosystems from nutrient pollution and pathogens.
