VILLAFRANCA Wastewater Treatment Plant, Villafranca de los Barros, Extremadura

VILLAFRANCA is a wastewater treatment plant located in Villafranca de los Barros, a municipality in the Tierra de Barros comarca of Badajoz, Extremadura, Spain. The plant serves a population of approximately 65,000 people, placing it in the medium-to-large agglomeration category under EU classification. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. Spain's national transposition of the directive mandates compliance with discharge standards to protect receiving water bodies. The plant's treatment processes are designed to meet these regulatory requirements, ensuring effluent quality aligns with environmental objectives. The treated effluent from VILLAFRANCA is discharged into the local watershed, which ultimately drains into the Guadiana River basin. The Guadiana River flows westward through Extremadura and into the Gulf of Cádiz (Atlantic Ocean). The plant plays a key role in protecting the region's water resources, supporting agricultural activities in the Tierra de Barros area, and maintaining downstream aquatic ecosystems.

The plant discharges into the Guadiana River basin, which flows through Extremadura and into the Gulf of Cádiz in the Atlantic Ocean. The Guadiana supports diverse aquatic life and is an important water source for agriculture in the region. The plant's operations help reduce nutrient and pollutant loads, protecting downstream water quality and ecological health in a semi-arid climate where water resources are critical.
