DAIMIEL Wastewater Treatment Plant, Daimiel, Castilla-La Mancha, Spain

The DAIMIEL wastewater treatment plant is located in Daimiel, a town in the province of Ciudad Real, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of around 29,548 residents, classifying it as a medium-sized agglomeration under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this scale. The directive requires appropriate treatment to protect receiving waters. The plant's location inland, far from the coast, influences its discharge requirements. The treated effluent is likely discharged into a local watercourse that feeds into the Guadiana River basin, which flows westward through the La Mancha region. The area is ecologically sensitive, supporting diverse aquatic life and important wetland habitats, including the nearby Tablas de Daimiel National Park, a vital wetland ecosystem.

The plant discharges into the Guadiana River basin, which flows through central Spain and eventually reaches the Atlantic Ocean via the Gulf of Cadiz. The region includes the Tablas de Daimiel wetland, a critical habitat for migratory birds and aquatic species. The plant's operations help maintain water quality in this semi-arid region, where water resources are under pressure from agriculture and climate variability.
