Torrenueva Wastewater Treatment Plant, Torrenueva, Castilla-La Mancha, Spain

The Torrenueva wastewater treatment plant is located in the municipality of Torrenueva, in the province of Ciudad Real, Castilla-La Mancha, Spain. The plant serves a population of approximately 5,505 residents, classifying it as a small agglomeration under Spanish and EU regulations. The plant provides secondary treatment, which is the minimum required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with EU standards before discharge. The treated effluent is discharged into local watercourses that drain into the Guadiana River basin, one of Spain's major river systems. The Guadiana River flows westward, eventually reaching the Gulf of Cádiz in the Atlantic Ocean. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from pollution.

The plant discharges into the Guadiana River basin, which supports diverse aquatic life and is an important water resource for agriculture and communities in Castilla-La Mancha and Extremadura. The Guadiana River ultimately flows into the Atlantic Ocean via the Gulf of Cádiz. The region's semi-arid climate makes water quality management critical for maintaining ecological balance and supporting downstream habitats.
