Villahermosa Wastewater Treatment Plant - Castilla-La Mancha, Spain

The Villahermosa wastewater treatment plant is located in the municipality of Villahermosa, in the province of Ciudad Real, within the autonomous community of Castilla-La Mancha, Spain. The facility serves a population of 2,744 and treats wastewater to the secondary level, which is the minimum standard required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. As a secondary treatment plant, Villahermosa removes biodegradable organic matter and suspended solids through biological processes. The plant handles a daily discharge volume of 415 cubic meters. The plant's scale aligns with typical infrastructure for small inland communities in Spain. The treated effluent is discharged into local watercourses that eventually drain into the Guadiana River basin, one of the major river systems in the Iberian Peninsula. The Guadiana River flows southwest through Spain and Portugal before emptying into the Gulf of Cadiz in the Atlantic Ocean. The plant's operations help protect the ecological health of these downstream waters.

The Villahermosa plant discharges into the Guadiana River basin, which flows through the semi-arid La Mancha region before reaching the Atlantic Ocean. The Guadiana supports diverse aquatic life and is an important water resource for agriculture and ecosystems. Secondary treatment reduces organic pollution and nutrients, helping to prevent eutrophication in downstream reservoirs and coastal waters.
