Overview
Los Barrios wastewater treatment plant serves the municipality of Los Barrios in Andalucía, Spain, with a population of approximately 18,083. The plant is located within 50 km of the coast and operates under EU regulations.
The Los Barrios wastewater treatment plant is a municipal facility serving the town of Los Barrios in the Campo de Gibraltar region of Cádiz, Andalucía, Spain. With a population equivalent of around 18,083, it falls under the EU classification of a medium agglomeration, requiring appropriate treatment under the Urban Waste Water Treatment Directive (91/271/EEC). As a plant in a European Union member state, Los Barrios is subject to the UWWTD, which mandates secondary treatment for agglomerations of this size discharging into coastal or estuarine waters. The designed capacity of 1.00 (likely in thousands of cubic meters per day or similar unit) suggests a facility sized to handle the local load. The regulatory framework ensures compliance with effluent standards. The plant's proximity to the coast (within 50 km) means its treated effluent likely discharges into the Mediterranean Sea via local watercourses or directly. The receiving water body is not named, but the area drains into the Bay of Algeciras, an ecologically important marine environment supporting diverse aquatic life and migratory species. The plant plays a key role in protecting coastal water quality and public health.
Environmental context
The Los Barrios plant discharges into the Bay of Algeciras, part of the Mediterranean Sea, which is a semi-enclosed basin with limited water exchange. The bay supports important marine habitats, including seagrass meadows and nursery grounds for fish. The plant's treatment performance directly affects the ecological health of this coastal environment, which is also influenced by industrial activity in the Campo de Gibraltar area.
