La Puebla de Valverde Wastewater Treatment Plant - Secondary Treatment in Aragón, Spain

La Puebla de Valverde wastewater treatment plant is located in the municipality of La Puebla de Valverde, within the Gúdar-Javalambre region of Aragón, Spain. The plant serves a population of 857 and operates with secondary treatment, meeting the standards required for small agglomerations under Spanish and EU regulations. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Its designed capacity is 2000 cubic meters per day, with an average discharge volume of 155.33 cubic meters per day, indicating ample capacity for current loads. The plant is part of Spain's compliance with the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The treated effluent is discharged into the local river system, which flows through the Ebro basin and ultimately reaches the Mediterranean Sea. The plant plays a key role in protecting the water quality of the region's streams and downstream ecosystems, supporting aquatic life and agricultural uses.

The plant discharges into a tributary of the Ebro River basin, which drains into the Mediterranean Sea. The local watershed supports diverse aquatic habitats and is important for irrigation and livestock. The secondary treatment helps reduce nutrient loads, mitigating eutrophication risks in downstream water bodies.
