Overview
UTRERA wastewater treatment plant serves the city of Utrera in Andalucía, Spain, with a population equivalent of 52,000. It operates under the EU Urban Waste Water Treatment Directive.
The UTRERA wastewater treatment plant is located in Utrera, a city in the province of Seville, Andalucía, Spain. Situated along the Carretera Utrera - Los Palacios, the facility serves a population equivalent of approximately 52,000 people, classifying it as a medium-sized agglomeration under European Union regulations. As a Spanish wastewater treatment plant, UTRERA is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale. The directive also requires more advanced treatment if the receiving waters are designated as sensitive areas. The plant's compliance with national and EU standards ensures appropriate treatment for the population served. The treated effluent from UTRERA is discharged into the local watershed, which ultimately drains into the Guadalquivir River basin. The Guadalquivir flows through Andalucía and empties into the Atlantic Ocean at the Gulf of Cádiz. This river system supports diverse aquatic life and is ecologically important for the region, including migratory bird species and wetland ecosystems along its course.
Environmental context
The UTRERA plant discharges into the Guadalquivir River basin, which flows southwest through Andalucía and into the Atlantic Ocean at the Gulf of Cádiz. This watershed supports a variety of aquatic habitats and is an important corridor for migratory birds. The downstream environment includes ecologically sensitive areas that benefit from regulated wastewater treatment to maintain water quality.
