Mosqueruela Wastewater Treatment Plant, Mosqueruela, Aragón, Spain

The Mosqueruela wastewater treatment plant is located in the municipality of Mosqueruela, within the Gúdar-Javalambre region of Teruel, Aragón, Spain. This facility serves a population of approximately 1,500 residents, providing secondary treatment to manage domestic wastewater from the community. The plant operates with a designed capacity of 2,500 cubic meters per day and currently discharges an average volume of 271.87 cubic meters per day. As a small agglomeration in Spain, the plant is subject to national regulations implementing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for inland freshwater discharges from settlements of this size. The treated effluent is discharged into a local watercourse that ultimately drains into the Mediterranean Sea via the Ebro River basin. The plant plays a key role in protecting the local environment by reducing organic load and nutrients before discharge, supporting the ecological health of the downstream aquatic systems.

The plant discharges into a local stream that flows into the Mijares River, which eventually reaches the Mediterranean Sea near Castellón. The surrounding watershed supports diverse aquatic life and is part of a region with agricultural and natural landscapes. The secondary treatment helps mitigate nutrient pollution, safeguarding water quality in the downstream river and coastal zone.
