It serves a population equivalent of 114,000, classifying it as a large agglomeration under the EU Urban Waste Water Treatment Directive (91/271/EEC). The plant is situated in a coastal urban area with industrial proximity. As a large agglomeration, the plant is required to meet secondary treatment standards under the EU UWWTD, with tertiary treatment mandated if discharging into sensitive areas. The designed capacity is 1. The plant operates under French national regulations implementing the directive. The treated effluent is discharged into the English Channel via the port area. The coastal environment supports diverse marine life and is part of the wider Normandy coastal ecosystem. The plant plays a key role in protecting local bathing waters and marine habitats from untreated wastewater.

The plant discharges into the English Channel near the Port of Tourlaville, which is part of the larger Bay of the Seine and ultimately the Atlantic Ocean. The coastal waters in this region support diverse marine life, including fish nurseries and migratory bird populations. The area is ecologically sensitive due to its proximity to the Cotentin Peninsula's rich intertidal zones and seagrass beds.
