Overview
ARROYOMOLINOS DE LEON is a closed advanced treatment plant in Arroyomolinos de León, Andalucía, Spain. It served 695 people with a designed capacity of 1,719 m³/day.
ARROYOMOLINOS DE LEON is a wastewater treatment plant located in the municipality of Arroyomolinos de León, in the Sierra de Huelva region of Andalucía, Spain. The plant served a small population of 695 people and was designed with a capacity of 1,719 cubic meters per day. It is currently closed. The plant provided advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. Advanced treatment typically includes nutrient removal to protect sensitive water bodies. The plant's discharge volume was recorded at 125.97 cubic meters per day. The area drains into the Guadiana River basin, which flows into the Gulf of Cádiz (Atlantic Ocean). The plant's location in a rural, inland area means its discharge would have affected local streams and groundwater before reaching larger watercourses.
Environmental context
The plant is located in the Sierra de Huelva, a mountainous region in the Guadiana River basin. The Guadiana River flows southward through Spain and Portugal, eventually discharging into the Gulf of Cádiz. The area supports diverse aquatic life and is important for migratory birds. The advanced treatment level would have helped protect downstream water quality in this ecologically sensitive region.
