Overview
SAINT JAMES wastewater treatment plant in Saint-Senier-de-Beuvron, Normandie, France, serves 5,080 people with advanced treatment and a designed capacity of 5,500 m³/day.
The SAINT JAMES wastewater treatment plant is located in Saint-Senier-de-Beuvron, a commune in the Manche department of Normandie, France. It serves a population of approximately 5,080 people, classifying it as a small to medium agglomeration under French regulations. The plant is situated near the coast, within 50 km of the English Channel, and its operations are subject to French and EU environmental standards. The plant employs advanced treatment processes, which go beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. Its designed capacity is 5,500 m³/day, and it discharges a daily volume of about 906 m³ of treated wastewater. The facility is operated as part of the municipal wastewater infrastructure, ensuring compliance with national water quality objectives. The treated effluent is discharged into the local watershed, which ultimately drains into the English Channel via the coastal rivers of the Manche region. The plant plays a key role in protecting the sensitive coastal environment, including nearby estuaries and marine habitats, from nutrient pollution and pathogens. Its advanced treatment helps maintain water quality for recreational and ecological uses.
Environmental context
The plant discharges into the local watershed that flows into the English Channel, a marine environment supporting diverse aquatic life and important fisheries. The coastal zone includes estuaries and intertidal habitats that are sensitive to nutrient loading. Advanced treatment reduces the risk of eutrophication and protects downstream ecosystems, including migratory fish corridors and shellfish beds.
Frequently asked questions
The plant is located at Route De La Manche, La Toutouterie, in the commune of Saint-Senier-de-Beuvron, within the Manche department of Normandie, France.
The plant serves approximately 5,080 people, making it a small to medium agglomeration under French and EU classification.
The treated wastewater is discharged into the local watershed, which flows into the English Channel. The plant uses advanced treatment to ensure effluent quality meets environmental standards.
As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 population equivalent. The plant exceeds this with advanced treatment.
For agglomerations of this size, the EU directive mandates secondary treatment. However, many plants in sensitive coastal areas, like SAINT JAMES, implement advanced treatment to further reduce nutrients and protect marine environments.
