Overview
Pedro Muñoz wastewater treatment plant serves the town of Pedro Muñoz in Castilla-La Mancha, Spain. It treats wastewater for approximately 8,167 residents under the EU Urban Waste Water Treatment Directive.
The Pedro Muñoz wastewater treatment plant is located in the municipality of Pedro Muñoz, in the province of Ciudad Real, within the autonomous community of Castilla-La Mancha, Spain. The facility serves a population of around 8,167 people, classifying it as a small agglomeration under Spanish and EU regulations. As a plant in Spain, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into inland waters. The treated effluent is discharged into the local watershed, which ultimately drains into the Guadiana River basin. The Guadiana River flows westward through central Spain and Portugal before reaching the Gulf of Cádiz (Atlantic Ocean). The plant plays a key role in protecting local water quality and the ecological health of the Guadiana basin.
Environmental context
The plant discharges into the Guadiana River basin, one of the major river systems in the Iberian Peninsula. The Guadiana flows through the arid plains of Castilla-La Mancha and Extremadura, supporting irrigated agriculture and diverse aquatic habitats. Downstream, the river forms part of the border between Spain and Portugal before emptying into the Gulf of Cádiz. The watershed is ecologically sensitive, hosting species such as the Iberian lynx and various waterfowl, making effective wastewater treatment critical for maintaining water quality and biodiversity.
