EL BARCO DE AVILA Wastewater Treatment Plant, El Barco de Ávila, Spain

EL BARCO DE AVILA is a wastewater treatment plant located in El Barco de Ávila, a municipality in the province of Ávila, Castilla y León, Spain. The plant serves a population equivalent of approximately 10,200, classifying it as a medium agglomeration under EU regulations. Its location in the mountainous region of central Spain influences the local water management needs. As a Spanish facility, the plant operates under 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 local water quality. The plant discharges treated wastewater into the Tormes River, which flows through the region and eventually joins the Duero River, a major watercourse in the Iberian Peninsula. The Duero River drains into the Atlantic Ocean near Porto, Portugal. The plant plays a key role in preserving the ecological health of the Tormes River, which supports diverse aquatic life and is used for irrigation and recreation.

The plant discharges into the Tormes River, a tributary of the Duero River basin. The Duero River flows westward through Spain and Portugal, emptying into the Atlantic Ocean. This watershed supports a variety of fish species and provides water for agriculture. The region's mountainous terrain and seasonal rainfall patterns influence river flow, making consistent treatment important for downstream ecosystems.
