Overview
Santovenia wastewater treatment plant serves Valladolid, Spain, treating municipal wastewater for approximately 7,000 residents with secondary treatment. The plant discharges treated effluent into the local water system.
Santovenia is a wastewater treatment plant located in Valladolid, within the Castilla y León region of Spain. It serves a population of around 7,000 people, making it a small to medium-sized facility in the area. The plant provides 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. The plant has a designed capacity of 7,000 cubic meters per day, matching the population served. The treated effluent is discharged into the local watershed, which ultimately drains into the Duero River basin. The Duero River flows westward through Spain and Portugal before reaching the Atlantic Ocean. The plant plays a key role in protecting the water quality of the Duero basin and downstream ecosystems.
Environmental context
The plant discharges into the Duero River basin, one of the major river systems in the Iberian Peninsula. The Duero flows through diverse landscapes, including agricultural areas and natural habitats, before emptying into the Atlantic Ocean near Porto, Portugal. The river supports a variety of aquatic life and is important for irrigation and drinking water supply downstream. Proper treatment at Santovenia helps reduce nutrient and pollutant loads, safeguarding the ecological health of the basin.
