TIERCE Wastewater Treatment Plant, Tiercé, Pays de la Loire, France

The TIERCE wastewater treatment plant is located in Tiercé, a commune in the Maine-et-Loire department of Pays de la Loire, France. The facility serves a population of approximately 3,704 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. As an advanced treatment plant, TIERCE goes beyond secondary treatment to remove nutrients and other pollutants, meeting stringent French and EU standards. The plant has a designed capacity of 4,750 m³/day and currently discharges an average of 660.79 m³/day, indicating significant reserve capacity for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River, one of France's major rivers. The Loire River flows into the Atlantic Ocean, supporting diverse aquatic ecosystems and providing water for agriculture and recreation. The plant's advanced treatment helps protect downstream water quality and ecological health.

The TIERCE plant discharges into the local watercourse that feeds into the Loire River, a major European river flowing through the Loire Valley to the Atlantic Ocean. The Loire basin supports diverse aquatic life, including migratory fish species such as Atlantic salmon and European eel. Advanced treatment at this plant reduces nutrient loading, helping to prevent eutrophication in downstream waters.
