PEDROCHE NUEVA Wastewater Treatment Plant, Pedroche, Andalusia, Spain

PEDROCHE NUEVA is a wastewater treatment plant located in the municipality of Pedroche, in the province of Córdoba, Andalusia, Spain. The plant serves a small population of 1,760 and is part of the region's municipal sanitation infrastructure, operating under Spanish and European Union regulations. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,600 m³/day and a current discharge volume of 319 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Guadalquivir River basin. The Guadalquivir River flows through Andalusia and empties into the Gulf of Cádiz (Atlantic Ocean). The plant's operation helps protect downstream water quality and supports the ecological health of the river system.

The plant discharges into the Guadalquivir River basin, which flows through southern Spain and into the Atlantic Ocean at the Gulf of Cádiz. The Guadalquivir is a major river supporting diverse aquatic life and agricultural irrigation. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in the river and its estuary, which is an important ecological zone for migratory birds and fish species.
