Overview
CENICERO wastewater treatment plant serves Elciego in the Basque Country, Spain. It treats wastewater from a population of 1,733 under the EU Urban Waste Water Treatment Directive.
CENICERO is a wastewater treatment plant located in Elciego, within the Basque Country (Euskadi) region of Spain. The facility serves a population of approximately 1,733 people, placing it in the small agglomeration category under EU regulations. As a Spanish plant, CENICERO operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The directive mandates secondary treatment for discharges to freshwater and estuaries for populations above 2,000, and appropriate treatment for smaller communities. The plant's treated effluent is discharged into the local watershed, which ultimately drains into the Ebro River basin. The Ebro River flows eastward through northern Spain before emptying into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural activities along its course.
Environmental context
CENICERO discharges into the Ebro River basin, which flows into the Mediterranean Sea via the Ebro Delta. The delta is an ecologically sensitive area that supports diverse aquatic life, including important fish species and migratory birds. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its effluent contributes to the overall water quality of the Ebro River system.
