QUIJORNA Wastewater Treatment Plant, Quijorna, Comunidad de Madrid, Spain

QUIJORNA is a wastewater treatment plant located in Quijorna, within the Comunidad de Madrid region of Spain. The facility serves a population of approximately 3,391 residents and is situated in an inland area away from the coast. The plant employs advanced treatment processes, meeting high standards for effluent quality. With a designed capacity of 12,548 m³/day and a current discharge volume of 777.50 m³/day, the plant operates well below its capacity, indicating room for future growth. As a Spanish facility, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The treated effluent is discharged into local watercourses that eventually drain into the Tagus River basin, one of the most important river systems in the Iberian Peninsula. The plant plays a key role in protecting downstream water quality and supporting the ecological health of the region's aquatic environments.

The plant discharges into local streams that flow into the Tagus River, which ultimately reaches the Atlantic Ocean near Lisbon. The Tagus basin supports diverse aquatic life and provides water for agriculture and urban use. Advanced treatment at this plant helps reduce nutrient loading and protects sensitive downstream habitats.
