Overview
Rochefort en Terre wastewater treatment plant serves Malansac, France, with advanced treatment for a population of 1,365. It discharges 243.51 cubic meters of treated wastewater daily.
The Rochefort en Terre wastewater treatment plant is located in Malansac, in the Brittany region of northwestern France. It serves a population of 1,365 and operates with advanced treatment processes, ensuring high-quality effluent before discharge. With a designed capacity of 3,100 cubic meters per day and an average daily discharge of 243.51 cubic meters, the plant operates well below its capacity. As a French facility, it complies with the European Union's Urban Waste Water Treatment Directive (91/271/EEC), which mandates advanced treatment for sensitive areas and secondary treatment for all agglomerations above 2,000 population equivalent. The plant's treated effluent is discharged into local waterways that eventually drain into the Atlantic Ocean. The receiving water body supports diverse aquatic life and contributes to the ecological health of the region's river systems. Proper treatment helps protect downstream environments from nutrient pollution and other contaminants.
Environmental context
The plant discharges into local streams that flow into the Vilaine River basin, which ultimately reaches the Atlantic Ocean via the Bay of Biscay. The downstream environment includes estuarine and coastal habitats that support migratory fish species and diverse aquatic ecosystems. Advanced treatment reduces nutrient loads, helping to prevent eutrophication in sensitive coastal waters.
