Overview
The ERNEE wastewater treatment plant serves the commune of Ernée in the Pays de la Loire region of France. It treats wastewater for approximately 8,070 residents.
The ERNEE wastewater treatment plant is located in the commune of Ernée, within the Mayenne department of the Pays de la Loire region in northwestern France. The facility serves a population of approximately 8,070 people, classifying it as a small to medium agglomeration under French and EU regulations. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are generally required to provide secondary treatment (biological treatment) for their wastewater. The plant operates within the French regulatory framework, which implements the directive through national legislation and permits issued by the local water agency (Agence de l'Eau). The treated effluent from the plant is discharged into the local watershed, which ultimately drains into the Mayenne River, a tributary of the Loire River. The Loire River is one of France's major rivers, flowing into the Atlantic Ocean. The plant plays a role in protecting the water quality of the Mayenne River and the downstream Loire estuary, supporting aquatic life and ecological balance.
Environmental context
The ERNEE plant discharges into the local watercourse that feeds into the Mayenne River, a tributary of the Loire River. The Loire River basin is ecologically significant, supporting diverse aquatic species and providing important habitats. The plant's operations help maintain water quality in this sensitive watershed, which ultimately drains into the Atlantic Ocean.
