Overview
MARMOLEJO wastewater treatment plant serves Marmolejo, Andalucía, Spain, with a population of 12,458. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
The MARMOLEJO wastewater treatment plant is located in Marmolejo, a municipality in the province of Jaén, within the autonomous community of Andalucía, Spain. The plant serves a population of approximately 12,458 people, classifying it as a medium-sized agglomeration under EU regulations. As a Spanish facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations with a population equivalent between 10,000 and 150,000. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into the local water system, which ultimately drains into the Guadalquivir River basin. The Guadalquivir River flows through Andalucía and empties into the Atlantic Ocean at the Gulf of Cádiz, supporting diverse aquatic ecosystems and agricultural water use along its course.
Environmental context
The MARMOLEJO plant discharges into the Guadalquivir River basin, which is the primary watercourse in Andalucía and flows into the Atlantic Ocean at the Gulf of Cádiz. The river supports a variety of aquatic life and is important for irrigation in the region. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the Guadalquivir watershed.
