TRUN Wastewater Treatment Plant, Trun, Normandy, France

The TRUN wastewater treatment plant is located in Trun, a commune in the Orne department of Normandy, France. It serves a population of approximately 1,590 residents, providing advanced treatment to protect local water quality. The plant's designed capacity is 3,000 m³/day, with an average daily discharge of 283.65 m³/day. As a French wastewater facility, TRUN operates under the national regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC). For agglomerations of this size (under 2,000 population equivalent), the directive requires appropriate treatment, and France has implemented advanced treatment standards to meet environmental objectives in sensitive areas. The treated effluent is discharged into local watercourses that drain into the Dives River basin, ultimately flowing into the English Channel. The plant plays a key role in preserving the ecological health of the surrounding Normandy countryside and downstream aquatic habitats.

The TRUN plant discharges into the local watershed that feeds the Dives River, which flows northward through the Pays d'Auge region before emptying into the English Channel at the Baie de Seine. This coastal zone supports diverse marine life and is an important area for migratory fish species. The advanced treatment helps reduce nutrient loads and protect the sensitive estuarine environment downstream.
