ALCALA DE HENARES ESTE Wastewater Treatment Plant, Camarma de Esteruelas, Spain

ALCALA DE HENARES ESTE is a municipal wastewater treatment plant located in Camarma de Esteruelas, within the Comunidad de Madrid, Spain. The plant serves a population of approximately 20,915, placing it in the medium agglomeration category under EU regulations. The plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. As a facility in an inland area, it contributes to the protection of local water resources and meets the regulatory standards set by Spanish authorities. The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Henares River, a tributary of the Jarama River, and then into the Tagus River. This river system supports diverse aquatic life and provides water for agricultural and urban uses downstream.

The plant discharges into the Henares River basin, which flows into the Jarama River and then the Tagus River, the longest river in the Iberian Peninsula. The Tagus River supports important ecosystems and provides water for irrigation and drinking water for millions of people. The plant's treatment helps protect water quality in this sensitive river system.
