Overview
The Andújar wastewater treatment plant serves approximately 38,000 residents in Andújar, Andalucía, Spain. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The Andújar wastewater treatment plant is located in the municipality of Andújar, in the province of Jaén, within the autonomous community of Andalucía, Spain. The facility serves a population of approximately 38,000 people, classifying it as a medium-sized agglomeration under European Union regulations. As a Spanish plant, Andújar operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for all discharges from agglomerations with a population equivalent (PE) greater than 2,000. For agglomerations between 10,000 and 150,000 PE, such as Andújar, secondary treatment is the standard, with tertiary treatment required if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into the local watershed, 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. The river supports diverse aquatic life and is an important ecological corridor in the region.
Environmental context
The Andújar plant discharges into the Guadalquivir River basin, which flows southwest through Andalucía to the Atlantic Ocean at the Gulf of Cádiz. The Guadalquivir is a major river supporting diverse aquatic ecosystems, including migratory fish species. The lower Guadalquivir and its estuary are ecologically sensitive areas that benefit from proper wastewater treatment to maintain water quality and biodiversity.
