La Ferté-Saint-Cyr Wastewater Treatment Plant, Centre-Val de Loire

The La Ferté-Saint-Cyr wastewater treatment plant, located in the Loir-et-Cher department of Centre-Val de Loire, France, serves a population of 889. The facility is situated at 8 Impasse du Moulin in the commune of La Ferté-Saint-Cyr, near the Loire River basin. The plant operates with secondary treatment, which is the standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations under 10,000 population equivalent. Its designed capacity is 2,400 m³/day, with an average discharge volume of 158.6 m³/day, indicating significant reserve capacity for future growth. The treated effluent is discharged into the local watershed, which ultimately drains into the Loire River, one of France's major waterways. The Loire River supports diverse aquatic ecosystems and is an important corridor for migratory fish species. The plant's secondary treatment helps protect downstream water quality in this ecologically sensitive region.

The plant discharges into the Loire River basin, which flows through the Centre-Val de Loire region before reaching the Atlantic Ocean. The Loire is known for its biodiversity, including populations of Atlantic salmon and European eel. Secondary treatment reduces organic pollutants and suspended solids, helping to maintain water quality in this ecologically important river system.
