Bohain-en-Vermandois Wastewater Treatment Plant | Hauts-de-France, France

The Bohain-en-Vermandois wastewater treatment plant is located in the Hauts-de-France region of northern France, serving the commune of Bohain-en-Vermandois and surrounding areas. With a population equivalent of approximately 14,451, it falls under the EU classification of a medium agglomeration, requiring appropriate treatment infrastructure to protect local water quality. As a French facility, the plant operates within the framework of the EU Urban Waste Water Treatment Directive (91/271/EEC), which sets minimum treatment standards based on population size and receiving water sensitivity. For agglomerations between 10,000 and 150,000 population equivalent, secondary treatment is typically required, with tertiary treatment in sensitive areas. The plant's inland location means it discharges to a freshwater system, likely the Somme River basin or a tributary. The treated effluent from the plant ultimately drains into the Somme River, which flows into the English Channel via the Baie de Somme. This coastal estuary is ecologically significant, supporting diverse bird populations and aquatic life. The plant's operation helps protect the Somme's water quality and the downstream marine environment from nutrient pollution and pathogens.

The plant discharges into the Somme River basin, which flows through the Picardy region before reaching the Baie de Somme, an important estuary on the English Channel. This coastal wetland supports migratory birds and diverse aquatic species. The plant's treatment processes help reduce nutrient loads and organic pollutants, protecting the downstream ecosystem from eutrophication and maintaining water quality for recreational and ecological uses.
