Overview
CINTRUENIGO wastewater treatment plant serves Cintruénigo, Navarra, Spain, with a population of 12,822. The plant operates under EU Urban Waste Water Treatment Directive 91/271/EEC, which mandates secondary treatment for agglomerations of this scale.
CINTRUENIGO is a wastewater treatment plant located in Cintruénigo, Navarra, Spain. It serves a population of approximately 12,822 people, placing it in the medium agglomeration category under EU regulations. The plant is situated inland, more than 50 km from the coast, and its treated effluent likely discharges into a local river system. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive 91/271/EEC, which requires secondary treatment for agglomerations with a population equivalent (PE) between 2,000 and 15,000. For this scale, secondary treatment is the standard, ensuring removal of organic matter and suspended solids. The regulatory framework ensures compliance with national and EU standards. The plant's receiving water body is not explicitly named, but given its location in the Ebro River basin, treated wastewater likely flows into a tributary of the Ebro River, which ultimately drains into the Mediterranean Sea. This discharge contributes to the ecological health of the river system, supporting aquatic life and downstream water quality.
Environmental context
The plant is located in the Ebro River basin, one of Spain's major hydrological systems. Treated wastewater from CINTRUENIGO likely discharges into a local tributary that feeds the Ebro River, which flows into the Mediterranean Sea near the Ebro Delta. The delta is an ecologically sensitive area supporting diverse aquatic life and important migratory bird populations. Proper treatment is essential to protect this downstream environment from nutrient pollution and contaminants.
