Villanueva de los Infantes Wastewater Treatment Plant, Castilla-La Mancha, Spain

The Villanueva de los Infantes wastewater treatment plant is located in the town of Villanueva de los Infantes, in the province of Ciudad Real, Castilla-La Mancha, Spain. It serves a population of around 8,266 residents, classifying it as a small to medium agglomeration 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. The directive aims to protect the environment from the adverse effects of urban wastewater discharges. The plant discharges treated wastewater into local watercourses that eventually drain into the Guadiana River basin, an important hydrological system in central Spain. The Guadiana River flows westward, forming part of the border with Portugal before reaching the Atlantic Ocean. The plant's operations help protect the ecological health of this river system and downstream environments.

The plant discharges into the Guadiana River basin, a major Iberian watershed that supports diverse aquatic life and agricultural irrigation. The Guadiana River flows through the La Mancha plain, a semi-arid region where water resources are critical. Downstream, the river forms the border with Portugal and eventually reaches the Atlantic Ocean, making the treatment plant's performance important for both Spanish and Portuguese water quality.
