Overview
COBENA wastewater treatment plant serves the municipality of Cobeña in the Comunidad de Madrid, Spain. It handles a population of approximately 5,338 people as part of the region's water infrastructure.
COBENA is a wastewater treatment plant located in Cobeña, within the Comunidad de Madrid, Spain. The facility serves a population of around 5,338 residents, placing it in the small agglomeration category under Spanish and EU regulations. Its location near the Camino del Barco provides access for municipal wastewater collection. As a small-scale plant in Spain, COBENA operates under the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. Spanish regulations transpose this directive through Royal Decree 509/1996, ensuring compliance with effluent standards. The plant's treatment processes are designed to meet these requirements, protecting local water quality. The treated effluent from COBENA is discharged into the local watershed, which ultimately drains into the Jarama River, a tributary of the Tagus River. The Tagus River flows westward through Spain and into Portugal, reaching the Atlantic Ocean near Lisbon. This downstream connection highlights the plant's role in safeguarding the ecological health of the Tagus basin, which supports diverse aquatic life and agricultural activities.
Environmental context
COBENA's treated wastewater enters the local drainage network, which flows into the Jarama River, a key tributary of the Tagus River. The Tagus is the longest river in the Iberian Peninsula, supporting ecosystems from central Spain to the Atlantic Ocean. The watershed is ecologically sensitive, providing habitat for fish species such as the Iberian barbel and serving as a migratory corridor for birds. Proper treatment at COBENA helps prevent nutrient pollution and maintains water quality in this important basin.
