Overview
Mansilla de las Mulas wastewater treatment plant serves 4,800 people in Castilla y León, Spain. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this size.
Mansilla de las Mulas wastewater treatment plant is located in the municipality of Mansilla de las Mulas, in the province of León, within the autonomous community of Castilla y León, Spain. The plant serves a population of approximately 4,800 residents, classifying it as a small 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 (PE) between 2,000 and 10,000 discharging into freshwater. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas. The plant's treated effluent is discharged into local watercourses that ultimately drain into the Esla River, a major tributary of the Duero River. The Duero basin supports diverse aquatic life and agricultural irrigation downstream, making proper wastewater treatment essential for maintaining water quality in this semi-arid region of Spain.
Environmental context
The plant discharges into the Esla River basin, which flows into the Duero River and eventually reaches the Atlantic Ocean near Porto, Portugal. The Duero basin is an ecologically sensitive area supporting migratory fish species such as the Iberian barbel and the European eel. Proper treatment helps protect these species and maintain water quality for downstream communities and agriculture.
