Overview
VIANA wastewater treatment plant serves the town of Viana in Navarra, Spain, with a population equivalent of 7,369. It operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
The VIANA wastewater treatment plant is located in Viana, a town in the autonomous community of Navarra, northern Spain. The plant serves a population equivalent of 7,369, classifying it as a small to medium agglomeration under EU classification. It is situated inland, approximately 50 km from the coast, and discharges into the Ebro River basin. As a Spanish facility, the plant operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (between 2,000 and 10,000 population equivalent), the directive requires secondary treatment or an equivalent level of treatment. It is expected to comply with Spanish regulations for wastewater treatment. The treated effluent from the VIANA plant ultimately flows into the Ebro River, one of Spain's major rivers, which drains into the Mediterranean Sea via the Ebro Delta. The Ebro Delta is an ecologically sensitive area that supports diverse aquatic life and important migratory bird populations. Proper treatment at plants like VIANA is crucial for protecting water quality in the Ebro basin and downstream ecosystems.
Environmental context
The VIANA plant discharges into the Ebro River basin, which flows through northeastern Spain and empties into the Mediterranean Sea via the Ebro Delta. The delta is a ecologically significant area that supports diverse aquatic life and serves as an important migratory corridor for birds. The plant's location inland, about 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the Ebro River system.
