Overview
CHAMPAGNE Le Gueribas is an advanced wastewater treatment plant in Champagné, Pays de la Loire, France, serving 2,750 people with a discharge volume of 490.60 m³/day.
CHAMPAGNE Le Gueribas is an advanced wastewater treatment plant located in Champagné, within the Sarthe department of Pays de la Loire, France. The facility serves a population of 2,750 and has a designed capacity of 2,666 m³/day, with an average discharge volume of 490.60 m³/day. As an advanced treatment plant, it goes beyond secondary treatment to remove nutrients and other pollutants, ensuring high-quality effluent. The plant operates under France's implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment levels based on the size of the agglomeration and the sensitivity of the receiving environment. For a plant serving fewer than 10,000 people, secondary treatment is typically sufficient, but the advanced level here indicates a sensitive area or specific local requirements. The 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 one of France's largest and most ecologically significant river systems, supporting diverse aquatic life and providing water for agriculture and human consumption. The plant's advanced treatment helps protect downstream water quality and the ecological health of the Loire estuary.
Environmental context
The plant discharges into the Sarthe River basin, which flows into the Loire River and eventually reaches the Atlantic Ocean. The Loire estuary is a critical habitat for migratory fish such as Atlantic salmon and European eel, and supports extensive wetlands. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters and protecting the ecological balance of the Loire watershed.
