The Cadalso de los Vidrios wastewater treatment plant is located in the municipality of Cadalso de los Vidrios, within the Comunidad de Madrid, Spain. It serves a population of approximately 3,564 residents, typical of a small agglomeration in the region. As a Spanish treatment plant, it operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 10,000 population equivalent), the directive requires appropriate treatment, typically secondary treatment, to protect receiving waters. The plant discharges treated effluent into local streams that ultimately drain into the Tagus River basin, which flows westward through central Spain and into Portugal, reaching the Atlantic Ocean near Lisbon. The Tagus basin supports diverse aquatic ecosystems and is an important water resource for the region.
Environmental context
The plant's treated effluent enters local watercourses within the Tagus River basin, one of the Iberian Peninsula's major river systems. The Tagus flows through central Spain and Portugal, supporting riparian habitats and agricultural water use before discharging into the Atlantic Ocean. The watershed is ecologically sensitive, hosting species such as the Iberian barbel and various waterfowl.
