Overview
LAVAL wastewater treatment plant serves the city of Laval in Pays de la Loire, France. It treats wastewater for approximately 187,550 people, operating under the EU Urban Waste Water Treatment Directive.
The LAVAL wastewater treatment plant is located in Laval, within the Pays de la Loire region of France. It serves a population of approximately 187,550, classifying it as a large agglomeration under EU regulations. The plant is situated along the Mayenne River, which is central to the local water management infrastructure. As a large agglomeration, the plant is expected to meet the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment as a minimum and tertiary treatment in sensitive areas. The plant's treatment processes are designed to comply with these standards, ensuring effective removal of pollutants before discharge. The treated effluent is discharged into the Mayenne River, which flows into the Loire River and eventually reaches the Atlantic Ocean. This discharge pathway underscores the plant's role in protecting downstream water quality and supporting the ecological health of the Loire basin, a region known for its diverse aquatic habitats and migratory fish species.
Environmental context
