BOSQUE EL Wastewater Treatment Plant, El Bosque, Andalucía, Spain

BOSQUE EL is a wastewater treatment plant located in El Bosque, a municipality in the Sierra de Cádiz region of Andalucía, Spain. The plant serves a population of approximately 3,675 residents and operates with 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. The plant has a designed capacity of 3,000 cubic meters per day and currently discharges an average volume of 666.08 m³/day. As a secondary treatment facility, it removes organic matter and suspended solids through biological processes, meeting the regulatory requirements for inland discharges in sensitive areas. The treated effluent is discharged into the local watershed, which ultimately drains into the Guadalete River basin and flows toward the Bay of Cádiz in the Atlantic Ocean. The plant plays a key role in protecting the region's water quality, supporting aquatic life in the surrounding rivers and contributing to the ecological health of the downstream coastal environment.

The plant discharges into the Guadalete River basin, which flows through the Sierra de Cádiz and eventually reaches the Bay of Cádiz in the Atlantic Ocean. This watershed supports diverse aquatic habitats and is important for migratory bird species. The secondary treatment provided by the plant helps maintain water quality in this ecologically sensitive region, reducing nutrient loads that could otherwise impact downstream ecosystems.
