Overview
Cuéllar wastewater treatment plant serves the town of Cuéllar in Segovia, Castilla y León, Spain. It treats wastewater from approximately 27,500 residents, supporting local water quality in the Duero River basin.
The Cuéllar wastewater treatment plant is located in the town of Cuéllar, in the province of Segovia, within the autonomous community of Castilla y León, Spain. The facility serves a population of approximately 27,500 people, making it a medium-sized agglomeration under Spanish and European Union classifications. As a plant operating in Spain, Cuéllar is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant is expected to meet these regulatory standards to protect the local environment. The treated effluent from the Cuéllar plant is discharged into the local water system, which ultimately drains into the Duero River basin. The Duero River flows westward through Spain and into Portugal, emptying into the Atlantic Ocean at Porto. This basin supports diverse aquatic life and is an important agricultural and ecological resource for the region.
Environmental context
The Cuéllar plant discharges into the Duero River basin, which flows through Castilla y León and into Portugal before reaching the Atlantic Ocean. The basin supports a variety of aquatic species and is a key water resource for irrigation and drinking water. Protecting water quality in this basin is essential for maintaining ecological balance and supporting downstream communities.
