HAMES BOUCRES Wastewater Treatment Plant, Hames-Boucres, Hauts-de-France

HAMES BOUCRES is a wastewater treatment plant located in the commune of Hames-Boucres, near Calais in the Hauts-de-France region of northern France. The facility serves a small population of approximately 750 residents and is situated in a rural area within the Pas-de-Calais department. As a coastal plant within 10 km of the English Channel, it plays a key role in protecting local marine waters. The plant employs advanced treatment processes, exceeding the secondary treatment standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 3,000 m³/day and a current discharge volume of 133.80 m³/day, the facility operates well below its capacity, indicating room for future growth or seasonal variations. The advanced treatment level ensures high-quality effluent suitable for discharge into sensitive coastal environments. The treated effluent is discharged into the local watershed, which drains into the English Channel via small coastal streams. This area is ecologically sensitive, supporting diverse marine life and serving as an important migratory corridor for seabirds. The plant's advanced treatment helps minimize nutrient and pollutant loads, contributing to the health of the Channel's coastal ecosystems and meeting France's obligations under the EU Water Framework Directive.

The plant discharges into the local drainage network that flows into the English Channel, a dynamic marine environment connecting the Atlantic Ocean to the North Sea. The coastal waters near Hames-Boucres support diverse aquatic life, including fish, crustaceans, and seabirds, and are part of a broader ecosystem that includes important nursery habitats. Advanced treatment at this facility reduces the risk of eutrophication and protects water quality in a region where tourism and fishing are economically significant.
