ALMUDEVAR Wastewater Treatment Plant, Almudévar, Aragón, Spain

The ALMUDEVAR wastewater treatment plant is located in Almudévar, a municipality in the province of Huesca, Aragón, Spain. Serving a population of approximately 5,802, the plant is part of the region's municipal wastewater infrastructure, ensuring that local sewage is treated before discharge into the environment. As a plant serving a small agglomeration (under 10,000 population equivalent), it falls under the requirements of the EU Urban Waste Water Treatment Directive 91/271/EEC. This directive mandates appropriate treatment for all agglomerations, with secondary treatment typically required for inland areas. The plant's operational context is shaped by Spanish national regulations that transpose EU directives, overseen by regional water authorities. The treated effluent from the plant is discharged into local watercourses that ultimately drain into the Ebro River basin, one of Spain's major river systems. The Ebro River flows eastward into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant plays a key role in protecting these downstream environments from pollution.

The plant discharges into the Ebro River basin, which flows into the Mediterranean Sea. This watershed supports diverse aquatic life and is important for regional agriculture. The plant's treatment helps protect downstream ecosystems from nutrient pollution and pathogens, contributing to the ecological health of the Ebro Delta, a sensitive coastal area.
