MONTREUIL Wastewater Treatment Plant, Montreuil-sur-Mer, Hauts-de-France

The MONTREUIL wastewater treatment plant is located in Montreuil-sur-Mer, a commune in the Pas-de-Calais department of Hauts-de-France, France. The plant serves a population of 6,017 and has a designed capacity of 1.00, placing it in the small agglomeration category under French regulations. As a French wastewater treatment plant, MONTREUIL operates under the national implementation of the EU Urban Waste Water Treatment Directive (91/271/EEC).

The plant's capacity and population served suggest it falls within this tier. The plant discharges into the local watershed, which ultimately drains into the English Channel via the Canche River. The Canche estuary is an ecologically sensitive area that supports diverse aquatic life and migratory birds. Proper treatment at MONTREUIL helps protect downstream water quality and the marine environment.
