Overview
FOURMIES wastewater treatment plant serves Wignehies in Hauts-de-France, France, with a population equivalent of 6,979. It operates under the EU Urban Waste Water Treatment Directive.
The FOURMIES wastewater treatment plant is located in Wignehies, a commune in the Nord department of Hauts-de-France, France. It serves a population of approximately 6,979 people, placing it in the small to medium agglomeration category under EU classification. As a French facility, the plant is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size. The directive also mandates appropriate treatment before discharge into inland waters, with more stringent requirements for sensitive areas. The plant's treated effluent likely discharges into a local watercourse that flows into the Helpe River system, part of the Sambre basin, which ultimately drains into the North Sea. This contributes to the ecological health of the regional waterways and supports aquatic biodiversity.
Environmental context
The plant discharges into the Helpe River system, a tributary of the Sambre, which flows into the Meuse River and eventually reaches the North Sea. This watershed supports diverse aquatic life and is important for regional water quality. The Hauts-de-France region has several sensitive areas where nutrient removal is required to prevent eutrophication.

The treated effluent is discharged into a local watercourse that flows into the Helpe River system, part of the Sambre basin, ultimately reaching the North Sea.
As a plant serving a population of 6,979, it falls under the EU UWWTD, which requires secondary treatment for agglomerations between 2,000 and 10,000 population equivalent. More stringent treatment may be required if the receiving waters are in a sensitive area.
In France, plants of this scale typically provide secondary biological treatment, often with activated sludge or similar processes, to meet EU standards for organic matter and suspended solids removal.
