Overview
TAFALLA OLITE wastewater treatment plant serves Olite/Erriberri in Navarra, Spain, with a population equivalent of 24,800. The plant operates under Spain's implementation of the EU Urban Waste Water Treatment Directive.
TAFALLA OLITE is a wastewater treatment plant located in Olite/Erriberri, in the region of Navarra, Spain. It serves a population equivalent of 24,800, classifying it as a medium-sized agglomeration under EU classification. The plant is situated inland, approximately 50 km from the coast, and discharges into the local watershed. As a Spanish facility, TAFALLA OLITE operates under the national transposition of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size, the directive requires secondary treatment as a minimum, with more stringent treatment in sensitive areas. Spain has designated numerous sensitive areas, particularly in the Ebro basin and coastal zones, which may influence the treatment requirements for this plant. The plant's treated effluent ultimately drains into the Ebro River basin, one of the largest river systems in Spain, which flows into the Mediterranean Sea. The Ebro basin supports diverse aquatic ecosystems and is an important agricultural region. Proper wastewater treatment is essential to protect water quality in this ecologically and economically significant watershed.
Environmental context
TAFALLA OLITE discharges into the Ebro River basin, which flows through northeastern Spain before reaching the Mediterranean Sea via the Ebro Delta. The delta is a vital wetland ecosystem supporting migratory birds and diverse aquatic life. The plant's treatment performance directly affects water quality in this sensitive downstream environment, where nutrient loading can impact coastal and marine habitats.
Frequently asked questions
TAFALLA OLITE is located in Olite/Erriberri, in the region of Navarra, Spain. The plant serves the municipalities of Olite and Tafalla, among others.
The plant serves a population equivalent of 24,800, classifying it as a medium-sized agglomeration under EU standards.
The plant discharges treated effluent into the Ebro River basin, which flows to the Mediterranean Sea. The plant is inland and likely discharges to a local stream or river within the Ebro watershed.
TAFALLA OLITE operates under Spain's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of 10,000-150,000 PE, the directive requires secondary treatment, with tertiary treatment in sensitive areas.
In Spain, plants serving around 25,000 PE typically provide secondary biological treatment as a minimum. In sensitive areas designated under the EU UWWTD, such as parts of the Ebro basin, additional nutrient removal may be required to protect water quality.
