CERVERA DEL RIO ALHAMA is a wastewater treatment facility located in Cervera del Río Alhama, a municipality in the La Rioja region of northern Spain. The plant serves a population of approximately 2,044 residents and is designed to handle up to 5,000 cubic meters of wastewater per day, with a current discharge volume of 484.04 m³/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. Secondary treatment typically involves biological processes to reduce organic matter and suspended solids, meeting the directive's requirements for inland discharges. The treated effluent is discharged into the local watershed, which ultimately drains into the Ebro River basin. The Ebro River is one of Spain's major rivers, flowing into the Mediterranean Sea. The plant plays a key role in protecting the water quality of the Alhama River and downstream ecosystems, supporting aquatic life and agricultural water use in the region.
Environmental context
The plant discharges into the Alhama River, a tributary of the Ebro River, which flows into the Mediterranean Sea. The Ebro basin supports diverse aquatic habitats and is an important agricultural region. Secondary treatment helps reduce nutrient loads and organic pollution, protecting downstream water quality and the ecological health of the river system.
