Connerré Wastewater Treatment Plant, Connerré, Pays de la Loire, France

The Connerré wastewater treatment plant is located in the commune of Connerré, within the Sarthe department of the Pays de la Loire region in northwestern France. The facility serves an estimated population of 8,000, classifying it as a small to medium agglomeration under EU classification. Its address is Rue des Lindennes, Connerré, Mamers, Sarthe, Pays de la Loire. As a French wastewater treatment plant serving a population between 2,000 and 10,000, the facility is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary treatment (biological treatment) for all discharges from agglomerations of this scale, unless the receiving waters are designated as sensitive areas, which may necessitate more advanced treatment. The regulatory framework ensures a minimum level of treatment. The treated effluent from the Connerré plant is discharged into local watercourses that ultimately drain into the Sarthe River, a tributary of the Loire River. The Loire River flows into the Atlantic Ocean, making the plant part of the Loire basin. The downstream environment supports diverse aquatic life and is important for regional water quality and ecological balance.

The Connerré plant discharges into the local watershed that feeds the Sarthe River, which joins the Loire River before reaching the Atlantic Ocean. The Loire basin is ecologically significant, hosting diverse fish species and migratory birds. The plant's discharge contributes to the overall water quality of the Sarthe and Loire rivers, which are used for drinking water, agriculture, and recreation downstream.
