Overview
LILLERS wastewater treatment plant serves the commune of Lillers in Hauts-de-France, France. It treats wastewater for approximately 10,833 residents, operating under the EU Urban Waste Water Treatment Directive.
The LILLERS wastewater treatment plant is located in Lillers, a commune in the Pas-de-Calais department of Hauts-de-France, northern France. The facility serves a population of around 10,833 people, classifying it as a medium-sized agglomeration under European Union regulations. As a French wastewater treatment plant, LILLERS operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates more stringent treatment if the receiving waters are designated as sensitive areas, such as those prone to eutrophication. The plant discharges treated effluent into the local watershed, which ultimately drains into the North Sea via the Lys River and the Scheldt estuary. This region supports diverse aquatic life and is important for migratory fish species. Proper treatment helps protect downstream water quality and ecological health.
Environmental context
The LILLERS plant discharges into the local water system that flows into the Lys River, a tributary of the Scheldt, which empties into the North Sea. The downstream environment includes agricultural and urban areas, and the river supports fish populations and aquatic biodiversity. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain water quality in this sensitive coastal basin.
