NEUILLE PONT PIERRE Cange Wastewater Treatment Plant, Neuillé-Pont-Pierre, France

NEUILLE PONT PIERRE Cange is an advanced wastewater treatment plant located in Neuillé-Pont-Pierre, a commune in the Indre-et-Loire department of the Centre-Val de Loire region, France. The plant serves a population of 2,183 and has a designed capacity of 2,500 m³/day, with a current discharge volume of 389.44 m³/day, indicating it operates well below its capacity. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. In France, such plants are regulated under national water law and typically require permits from the local water agency (Agence de l'Eau). The advanced treatment likely includes nutrient removal to protect sensitive receiving waters. The treated effluent is discharged into the local watershed, which is part of the Loire River basin. The Loire is one of France's major rivers, flowing into the Atlantic Ocean. The plant's location inland, over 50 km from the coast, reduces direct marine impact, but its discharge contributes to the overall water quality of the Loire basin, which supports diverse aquatic ecosystems and is important for regional water resources.

The plant discharges into the Escotais stream, a tributary of the Loire River. The Loire flows through central France and empties into the Atlantic Ocean near Saint-Nazaire. The watershed supports a variety of aquatic life, including migratory fish species such as Atlantic salmon and European eel. The advanced treatment helps protect downstream water quality in this ecologically significant river system.
