Villamanta Wastewater Treatment Plant - Secondary Treatment, Comunidad de Madrid, Spain

The Villamanta wastewater treatment plant is located in the municipality of Villamanta, within the Comunidad de Madrid region of Spain. It serves a population of approximately 2,923 residents, classifying it as a small agglomeration under EU directives. The plant is situated inland, away from coastal areas, and its operations are part of the regional wastewater infrastructure managed by the local authorities. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 4,000 m³/day and an average discharge volume of 653.06 m³/day, the facility operates well within its capacity, ensuring effective treatment of municipal wastewater. The treatment process likely involves biological treatment to reduce organic matter and suspended solids. The treated effluent is discharged into a local watercourse, which ultimately drains 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's operations contribute to protecting the local aquatic environment and downstream water quality in the Tagus basin.

The plant discharges into a tributary of the Tagus River, which flows through central Spain and Portugal to the Atlantic Ocean. The Tagus basin supports diverse aquatic life and is an important ecological corridor. The plant's secondary treatment helps reduce nutrient and organic pollution, safeguarding the river's health and downstream ecosystems.
