ARACENA NUEVA Wastewater Treatment Plant, Aracena, Andalucía, Spain

ARACENA NUEVA is a wastewater treatment plant located in Aracena, within the Sierra de Huelva region of Andalucía, Spain. The plant serves a population of around 10,341, classifying it as a medium agglomeration under the EU Urban Waste Water Treatment Directive (UWWTD). As a facility in a sensitive area, it is expected to meet secondary or tertiary treatment standards to protect local water bodies. The plant operates under Spain's implementation of the EU UWWTD, which mandates secondary treatment for agglomerations of this size. The regulatory framework ensures compliance with effluent quality standards. The plant's capacity and discharge volume are managed to align with population demands and environmental requirements. The treated effluent likely discharges into a local river or stream within the Guadalquivir basin, ultimately flowing into the Atlantic Ocean. The plant plays a key role in protecting the region's water quality, supporting aquatic life, and preserving the ecological balance of the Sierra de Huelva area.

The plant's discharge likely enters a tributary of the Guadalquivir River basin, which drains into the Gulf of Cádiz in the Atlantic Ocean. This watershed supports diverse aquatic habitats and is important for migratory fish species. The region's Mediterranean climate with seasonal rainfall influences flow patterns, making consistent treatment essential for downstream ecological health.
