VILLAFRANCA is a wastewater treatment plant located in Villafranca, within the Navarra region of Spain. It serves a population of approximately 3,942 people, classifying it as a small agglomeration under EU regulations. The plant is situated inland, away from coastal areas, and plays a key role in managing local wastewater. The plant provides secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. It has a designed capacity of 6,633 m³/day and currently treats a daily volume of 608 m³, indicating significant available capacity.

The treated effluent is discharged into a local water body, contributing to the protection of the Ebro River basin, which ultimately flows into the Mediterranean Sea. The plant's operation helps maintain water quality in the region, supporting aquatic life and downstream ecosystems. Its inland location reduces direct marine impact, but proper treatment remains essential for the health of the river system.
Environmental context
The plant discharges into a tributary of the Ebro River, which flows through northeastern Spain into the Mediterranean Sea. The Ebro basin supports diverse aquatic habitats and is an important agricultural and ecological corridor. Secondary treatment helps reduce nutrient loads and organic pollution, protecting downstream water quality and the sensitive delta ecosystem.
