POLIGONO INDUSTRIAL SAN ROQUE Wastewater Treatment Plant, San Roque, Andalucía

POLIGONO INDUSTRIAL SAN ROQUE is a wastewater treatment plant located in the industrial area of San Roque, within the Campo de Gibraltar region of Andalucía, Spain. The plant served a small population of 1,166 and was designed with a capacity of 2,500 m³/day, though it is now closed. As a secondary treatment facility, the plant would have met the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's discharge volume was recorded at 211.33 m³/day, indicating it operated well below its designed capacity. The plant is situated within 10 km of the Mediterranean coast, meaning its treated effluent likely discharged into coastal waters. The proximity to the coast suggests potential impact on marine ecosystems. The plant's closure may reflect changes in industrial activity or consolidation of treatment infrastructure in the region.

The plant is located in the Campo de Gibraltar, a coastal area near the Strait of Gibraltar, which connects the Mediterranean Sea to the Atlantic Ocean. This region supports diverse marine life and is an important migratory corridor for birds and marine species. Treated effluent from the plant would have discharged into the Mediterranean Sea, potentially affecting local water quality and coastal ecosystems. The area is also influenced by industrial activities, including petrochemical and port operations.
