Balazote Wastewater Treatment Plant: Serving Balazote, Castilla-La Mancha, Spain

The Balazote wastewater treatment plant is located in the municipality of Balazote, within the province of Albacete in the autonomous community of Castilla-La Mancha, Spain. The facility serves a population of approximately 4,615 residents, making it a small-scale municipal treatment plant typical of rural inland communities in the region. The plant operates with secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations with a population equivalent between 2,000 and 10,000. The directive mandates secondary treatment for such communities to reduce organic matter and suspended solids before discharge into receiving waters. The treated effluent is discharged into local watercourses that eventually drain into the Guadalquivir River basin, which flows southwest to the Atlantic Ocean. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from untreated wastewater pollution.

The plant discharges into the local drainage network that feeds into the Guadalquivir River basin, one of Spain's major river systems. The Guadalquivir flows through Andalusia and empties into the Gulf of Cadiz, supporting diverse aquatic life and important wetlands. The secondary treatment provided by the plant helps reduce nutrient and organic loads, protecting downstream water quality and ecological health.
