The Estepona wastewater treatment plant is located in the coastal municipality of Estepona, within the province of Málaga in the autonomous community of Andalusia, Spain. It serves a population equivalent of 96,422, classifying it as a large agglomeration under EU regulations. The plant is situated near the Mediterranean coast, less than 50 km from the shoreline. As a facility in Spain, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. For discharges to coastal waters, the directive may allow primary treatment under certain conditions, but given the population served, advanced treatment is expected to protect the marine environment. The designed capacity is 1. The plant discharges treated wastewater into the Mediterranean Sea, likely via a marine outfall. The Costa del Sol region is a densely populated tourist area, making effective wastewater treatment critical for protecting coastal water quality, bathing beaches, and marine ecosystems. The receiving waters support diverse marine life and are important for local fisheries and tourism.

Environmental context

The plant discharges into the Mediterranean Sea along the Costa del Sol, a semi-enclosed sea with limited water exchange. The coastal waters near Estepona are ecologically sensitive, supporting seagrass meadows and marine habitats. Downstream, the Mediterranean receives inflows from multiple rivers, but the plant's discharge directly affects local coastal water quality, which is vital for tourism and marine biodiversity.
