Overview
NOGENT wastewater treatment plant in Nogent, Grand Est, France, serves 2,900 people with advanced treatment. It discharges 517.35 m³/day and has a designed capacity of 6,167 m³/day.
The NOGENT wastewater treatment plant is located in Nogent, a commune in the Haute-Marne department of the Grand Est region, France. The facility serves a population of approximately 2,900 residents, classifying it as a small agglomeration under French and EU regulations. The plant employs advanced treatment processes, which go beyond the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Advanced treatment typically includes nutrient removal (nitrogen and phosphorus) to protect sensitive receiving waters. The plant has a designed capacity of 6,167 m³/day and currently treats an average daily flow of 517.35 m³/day, indicating significant reserve capacity. The treated effluent is discharged into local watercourses that ultimately drain into the Seine River basin, flowing northward through the Paris Basin and into the English Channel. The plant's advanced treatment helps protect downstream aquatic ecosystems and supports water quality objectives for the Seine-Normandy river basin district.
Environmental context
The plant discharges into the local watershed, which is part of the Seine River basin. The Seine flows through the Paris Basin and into the English Channel, supporting diverse aquatic life and providing water for agriculture and industry. The advanced treatment at NOGENT reduces nutrient loads, helping to prevent eutrophication in downstream rivers and coastal zones.

The NOGENT plant is located in Nogent, in the Haute-Marne department of the Grand Est region, France. The address is Rue du 11 Novembre, Nogent-le-Bas, 52800.
The plant serves approximately 2,900 people, making it a small agglomeration under EU classification.
The plant uses advanced treatment processes, which include nutrient removal (nitrogen and phosphorus) in addition to secondary biological treatment. This ensures high-quality effluent before discharge.
The treated effluent from NOGENT flows into local streams that are part of the Seine River basin. The Seine ultimately discharges into the English Channel, so the plant helps protect both freshwater and marine environments.
Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations with a population equivalent (PE) between 2,000 and 10,000 require secondary treatment. NOGENT exceeds this standard with advanced treatment, likely due to the sensitivity of the receiving waters.
