Overview
PRADOLUENGO wastewater treatment plant serves the town of Pradoluengo in Castilla y León, Spain. It provides secondary treatment for a population of 3,800 and discharges treated water into the local river system.
PRADOLUENGO is a municipal wastewater treatment plant located in Pradoluengo, a town in the province of Burgos, Castilla y León, Spain. The facility serves a population of approximately 3,800 residents, reflecting the scale of a small agglomeration. It is situated inland, away from coastal areas, and its operations are part of the region's water management infrastructure. The plant employs secondary treatment, which is the standard biological process required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. The directive mandates secondary treatment for all discharges from populations between 2,000 and 10,000 in freshwater areas. The plant's designed capacity of 3,800 cubic meters per day aligns with the population served, indicating adequate sizing for current demand. The treated effluent is discharged into a local watercourse, which eventually drains into the Ebro River basin, one of Spain's major river systems. The Ebro River flows eastward into the Mediterranean Sea, supporting diverse aquatic ecosystems and agricultural activities along its course. The plant's secondary treatment helps protect downstream water quality and ecological health.
Environmental context
The plant discharges into a tributary of the Ebro River basin, which flows through northeastern Spain into the Mediterranean Sea. The Ebro Delta is an ecologically sensitive area that supports diverse birdlife and aquatic species. Secondary treatment reduces organic pollutants and suspended solids, mitigating eutrophication risks in downstream waters.
