LUCENA DEL PUERTO Wastewater Treatment Plant, Lucena del Puerto, Andalucía

LUCENA DEL PUERTO is a wastewater treatment plant located in Lucena del Puerto, a municipality in the El Condado region of Huelva, Andalucía, Spain. The plant serves a population of approximately 2,350 residents, reflecting its role in managing domestic wastewater for this small inland community. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 2,350 cubic meters per day and a current discharge volume of 425.93 cubic meters per day, the facility operates well within its capacity. The treated effluent is discharged into local watercourses that eventually drain into the Atlantic Ocean via the Guadalquivir River basin. The plant's advanced treatment helps protect downstream ecosystems, including the Doñana National Park area, a critical wetland for migratory birds and biodiversity.

The plant discharges into local streams that flow into the Guadalquivir River, which empties into the Gulf of Cádiz in the Atlantic Ocean. The downstream environment includes ecologically sensitive areas such as the Doñana wetlands, a vital habitat for waterfowl and endangered species. Advanced treatment reduces nutrient loads, supporting the ecological health of these downstream ecosystems.
