Alcaudete de la Jara Wastewater Treatment Plant, Castilla-La Mancha, Spain

The Alcaudete de la Jara wastewater treatment plant is located in the municipality of Alcaudete de la Jara, in the province of Toledo, within the autonomous community of Castilla-La Mancha, Spain. The plant serves a population of 2,505 residents, treating domestic wastewater from the town. The plant operates with secondary treatment, which is the standard level required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, ensuring compliance with European effluent quality standards. The treated effluent is discharged into the local hydrological network, which ultimately drains into the Tagus River basin. The Tagus River is the longest river in the Iberian Peninsula and flows westward into the Atlantic Ocean near Lisbon. The plant plays a key role in protecting the water quality of local streams and the downstream Tagus ecosystem.

The plant discharges into the Tagus River basin, which supports diverse aquatic life and provides water for agriculture and human consumption. The Tagus River flows through central Spain and Portugal, eventually reaching the Atlantic Ocean. Protecting this watershed is important for maintaining ecological balance and water quality in the region.
