The OSUNA wastewater treatment plant is located in Osuna, a town in the province of Seville, within the autonomous community of Andalucía, Spain. The facility serves a population of about 26,353, classifying it as a medium agglomeration under European Union regulations. As a Spanish plant, OSUNA is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for discharges from agglomerations with a population equivalent between 10,000 and 150,000. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures a minimum level of treatment. The treated effluent from OSUNA is discharged into the local watershed, which ultimately drains into the Guadalquivir River basin. The Guadalquivir River flows through Andalucía and empties into the Atlantic Ocean near Sanlúcar de Barrameda. The river supports diverse aquatic life and is an important ecological corridor in southern Spain.
Environmental context
The OSUNA plant discharges into the Guadalquivir River basin, which flows through Andalucía and into the Atlantic Ocean. The Guadalquivir is a major river supporting diverse aquatic ecosystems, including migratory fish species. The plant's location inland reduces direct marine impact, but its effluent contributes to the overall water quality of the basin, which is used for irrigation and supports wetlands of ecological importance.

As a Spanish plant, OSUNA operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of its size. The directive also requires more stringent treatment if the receiving waters are sensitive.
Under the EU Urban Waste Water Treatment Directive, plants serving between 10,000 and 150,000 population equivalent are required to have at least secondary treatment. In Spain, this typically involves biological treatment processes to reduce organic matter and suspended solids.
