CASTILLEJAR Wastewater Treatment Plant, Castilléjar, Andalucía, Spain

CASTILLEJAR is a wastewater treatment plant located in Castilléjar, a municipality in the province of Granada, Andalucía, Spain. The plant serves a population of approximately 2,000 people, reflecting its role as a small-scale facility for the local community. It is situated in the inland region of Andalucía, away from coastal areas. 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. The plant's designed capacity is 2,000 cubic meters per day, matching the population served. However, the plant is currently closed, and its operational status is listed as closed. The treated effluent from the plant would have been discharged into a local watercourse, likely a tributary of the Guadalquivir River basin, which ultimately drains into the Atlantic Ocean. The plant's closure may impact local water quality, but the surrounding environment includes agricultural lands and natural areas that benefit from proper wastewater management.

The plant is located inland in the Guadalquivir River basin, which drains into the Atlantic Ocean. The local watershed supports agricultural activities and natural habitats. Proper wastewater treatment is essential to protect downstream water quality and aquatic life in the region's rivers and streams.
