Noyen-sur-Sarthe Wastewater Treatment Plant - Route de Malicorne, Pays de la Loire

The Noyen-sur-Sarthe wastewater treatment plant, located on Route de Malicorne in the commune of Noyen-sur-Sarthe, Pays de la Loire, France, serves a population of approximately 1,550. This facility is part of the municipal wastewater infrastructure for the Sarthe department and operates under French regulations transposing the EU Urban Waste Water Treatment Directive. The plant provides advanced treatment, which goes beyond the secondary treatment standard required by the EU directive for agglomerations of this size. With a designed capacity of 2,150 m³/day and an average daily discharge volume of 276.52 m³, the plant operates well below its capacity, indicating room for future growth or seasonal variations. Treated effluent is discharged into the local watershed, which ultimately drains into the Sarthe River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and serving as a migratory corridor for species such as Atlantic salmon. The plant's advanced treatment helps protect downstream water quality in this sensitive river system.

The plant discharges into the Sarthe River basin, which flows into the Loire River, one of France's longest rivers, emptying into the Atlantic Ocean. The Loire estuary and its floodplains support diverse aquatic habitats and are important for migratory fish. Advanced treatment at this plant reduces nutrient and pollutant loads, helping to maintain water quality in this ecologically sensitive watershed.
