Overview
CEBREROS wastewater treatment plant serves the municipality of Cebreros in Ávila, Castilla y León, Spain. It treats wastewater from approximately 11,500 residents.
CEBREROS is a wastewater treatment plant located in Cebreros, a municipality in the province of Ávila, within the autonomous community of Castilla y León, Spain. The plant serves a population of around 11,500 people, placing it in the medium agglomeration category under Spanish and EU regulations. As a Spanish facility, CEBREROS operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations of this size. The plant is also subject to Spanish national water legislation and regional oversight by the Junta de Castilla y León. The treated effluent from CEBREROS is discharged into a local watercourse that eventually drains into the Alberche River, a tributary of the Tagus River (Tajo). The Tagus flows westward through Spain and Portugal before reaching the Atlantic Ocean near Lisbon. The receiving waters support diverse aquatic life and are used for irrigation and recreation downstream.
Environmental context
The plant discharges into a small stream that feeds the Alberche River, which joins the Tagus River basin. The Tagus is one of the longest rivers in the Iberian Peninsula, supporting a variety of fish species and riparian habitats. Downstream, the river flows through agricultural areas and provides water for human consumption and irrigation. The ecological health of the Alberche and Tagus depends on effective wastewater treatment to prevent nutrient enrichment and pollution.
