The Châtillon-Coligny wastewater treatment plant is located in the commune of Châtillon-Coligny, within the Loiret department of the Centre-Val de Loire region, France. The facility serves a population of 2,218 and is classified as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a design capacity of 3,500 m³/day and an average daily discharge of 395.69 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River basin. The Loire is one of France's major rivers, supporting diverse aquatic ecosystems and providing water for agriculture and drinking water downstream. The plant's advanced treatment helps protect the receiving water body from nutrient pollution and other contaminants.
Environmental context
The plant discharges into the Loire River basin, which flows through central France before emptying into the Atlantic Ocean. The Loire is known for its ecological diversity, including migratory fish species such as salmon and eels. Advanced treatment at this plant reduces the risk of eutrophication and protects downstream water quality in this sensitive river system.
