RUAUDIN Chemin n92 Wastewater Treatment Plant, Ruaudin, France

RUAUDIN Chemin n92 is a wastewater treatment facility located in Ruaudin, within the Sarthe department of Pays de la Loire, France. The plant serves a population of approximately 3,800 residents and has a designed capacity of 4,000 m³/day, with a current discharge volume of 677.91 m³/day. As a French plant, it operates under national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for agglomerations of this size. The plant employs advanced treatment processes, exceeding the EU's minimum secondary treatment standard. This level of treatment is typical for facilities discharging into sensitive areas or where higher water quality standards are required. The plant's capacity utilization appears moderate, indicating operational flexibility to handle future population growth or seasonal variations. The treated effluent is discharged into local watercourses that ultimately drain into the Sarthe River, a tributary of the Loire River. The Loire basin is ecologically significant, supporting diverse aquatic life and serving as a migratory corridor for fish species. The plant's advanced treatment helps protect downstream water quality in this important river system.

The plant discharges into local streams that flow into the Sarthe River, part of the Loire River basin. The Loire is one of Europe's last wild rivers, supporting diverse aquatic ecosystems and migratory fish. Advanced treatment at this plant helps reduce nutrient loads and protect downstream water quality in this ecologically sensitive watershed.
