Yunquera de Henares Wastewater Treatment Plant | Secondary Treatment, Population 2,500

The Yunquera de Henares wastewater treatment plant is located in the town of Yunquera de Henares, in the province of Guadalajara, Castilla-La Mancha, Spain. The plant serves a population of approximately 2,500 residents, providing essential wastewater treatment for this inland community. The plant operates with secondary treatment, which is the standard biological treatment 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 the effluent meets quality standards before discharge. The treated wastewater is discharged into the local water environment, ultimately contributing to the Henares River basin. The Henares River flows into the Jarama River, a tributary of the Tagus River, which is the longest river in the Iberian Peninsula. The Tagus River drains into the Atlantic Ocean near Lisbon, Portugal. The plant plays a key role in protecting the water quality of these downstream water bodies.

The plant discharges into the Henares River basin, which flows into the Jarama River and then the Tagus River. The Tagus River is a major watercourse supporting diverse aquatic life and providing water for agriculture and urban use. The plant's secondary treatment helps reduce nutrient and organic pollution, protecting the ecological health of the river system.
