Valdemorillo Wastewater Treatment Plant, Valdemorillo, Comunidad de Madrid, Spain

The Valdemorillo wastewater treatment plant is located in the municipality of Valdemorillo, within the Comunidad de Madrid, Spain. It serves a population of around 7,284 residents, making it a small-scale facility in the region. The plant is situated inland, away from coastal areas, and its operations are part of the local water management infrastructure. As a Spanish wastewater treatment facility, Valdemorillo operates under the national regulations that transpose the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations with a population equivalent between 2,000 and 10,000, the directive requires appropriate treatment, typically secondary treatment, to protect receiving water bodies. The plant's treatment processes are designed to meet these standards, ensuring compliance with environmental quality objectives. The treated effluent from the Valdemorillo plant is discharged into local watercourses that eventually drain into the Tagus River basin, one of the major river systems in the Iberian Peninsula. The Tagus River flows westward through Spain and Portugal, emptying into the Atlantic Ocean near Lisbon. The plant plays a key role in protecting the local aquatic environment and downstream ecosystems from pollution.

The Valdemorillo plant discharges into the Tagus River basin, which supports diverse aquatic life and provides water for agriculture and urban use. The Tagus River ultimately flows into the Atlantic Ocean, making the plant's treatment performance important for both local and downstream water quality. The region's Mediterranean climate, with seasonal droughts, underscores the need for effective wastewater management to maintain ecological balance.
