MANSLE Wastewater Treatment Plant, Mansle-les-Fontaines, Nouvelle-Aquitaine

The MANSLE wastewater treatment plant is located in Mansle-les-Fontaines, a commune in the Charente department of Nouvelle-Aquitaine, France. It serves a population of approximately 2,450 residents, classifying it as a small agglomeration under French and EU regulations. The plant is situated near the Charente River, which flows through the region and ultimately reaches the Atlantic Ocean. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive water bodies. The designed capacity is 4,400 m³/day, with a current discharge volume of 437.08 m³/day, indicating ample reserve capacity. The treated effluent is discharged into the local watershed, likely the Charente River or its tributaries. The Charente River supports diverse aquatic life and is an important ecological corridor in the region. Downstream, the river flows into the Pertuis d'Antioche strait on the Atlantic coast, contributing to the marine environment. The plant's advanced treatment helps protect both freshwater and coastal ecosystems from nutrient pollution.

The plant discharges into the Charente River basin, which drains into the Atlantic Ocean via the Pertuis d'Antioche. The Charente River supports a variety of fish species and provides habitat for migratory birds. Advanced treatment at this plant reduces nutrient loads, helping to prevent eutrophication in downstream coastal waters, which are ecologically sensitive areas.
