Overview
Villanueva de Sigena wastewater treatment plant serves the municipality in Huesca, Aragón, Spain. It provides secondary treatment for a population of 1,148 with a designed capacity of 2,000 m³/day.
Villanueva de Sigena wastewater treatment plant is located in the municipality of Villanueva de Sigena, in the province of Huesca, within the autonomous community of Aragón, Spain. The plant serves a population of approximately 1,148 residents and operates with a designed capacity of 2,000 cubic meters per day, treating an average discharge volume of 208.07 cubic meters per day. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for populations between 2,000 and 10,000 population equivalent (PE) discharging into freshwater, and Spain has implemented this through national regulations. The plant's capacity utilization is low, indicating it is operating well below its design capacity. The treated effluent is discharged into a local watercourse within the Ebro River basin, which ultimately flows into the Mediterranean Sea. The plant plays a key role in protecting the local environment by reducing organic pollution and nutrients before discharge, supporting the ecological health of the downstream water bodies.
Environmental context
The plant discharges into a tributary of the Ebro River, which flows into the Mediterranean Sea via the Ebro Delta, an ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. The region's semi-arid climate means water resources are limited, making effective wastewater treatment crucial for maintaining water quality in the basin.
