Overview
BIESCAS wastewater treatment plant serves the municipality of Biescas in Aragón, Spain. It treats wastewater from a population of approximately 5,769 people.
The BIESCAS wastewater treatment plant is located in the municipality of Biescas, in the province of Huesca, within the autonomous community of Aragón, Spain. The plant serves a population of approximately 5,769 people, making it a small to medium-sized facility under Spanish and EU classifications. As a plant in the European Union, BIESCAS 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 stringent treatment if the receiving waters are designated as sensitive areas. The plant is expected to comply with these EU standards. The treated effluent from BIESCAS is discharged into a local watercourse that eventually drains into the Gállego River, a tributary of the Ebro River. The Ebro River flows into the Mediterranean Sea via the Ebro Delta, an ecologically important area. The plant plays a key role in protecting the local watershed and downstream aquatic ecosystems from pollution.
Environmental context
The BIESCAS plant discharges into a local stream that feeds the Gállego River, part of the Ebro River basin. The Ebro River flows into the Mediterranean Sea through the Ebro Delta, a region of high ecological value that supports diverse aquatic life and migratory birds. The plant's operation helps maintain water quality in this sensitive downstream environment.
