Setenil de las Bodegas Wastewater Treatment Plant | Andalucía, Spain

The Setenil de las Bodegas wastewater treatment plant is located in the Sierra de Cádiz region of Andalucía, Spain. It serves the town of Setenil de las Bodegas, a municipality known for its unique cave dwellings. The plant treats wastewater from a population of approximately 5,000 people. As a secondary treatment facility, the plant removes organic matter and suspended solids through biological processes. The plant has a designed capacity of 3,300 cubic meters per day and currently discharges a daily volume of 906.24 cubic meters. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), plants serving agglomerations of this size are required to provide secondary treatment, which this facility meets. The treated effluent is discharged into the local watershed, which ultimately drains into the Guadalete River basin and then into the Atlantic Ocean. The plant plays a key role in protecting the region's water quality and supporting the ecological health of downstream aquatic environments.

The plant discharges into the Guadalete River basin, which flows through the province of Cádiz and empties into the Bay of Cádiz in the Atlantic Ocean. The downstream environment supports diverse aquatic life and is important for local fisheries and tourism. The plant's secondary treatment helps reduce nutrient loads that could otherwise contribute to eutrophication in the coastal waters.
