NOEUX LES MINES NELLE SE Wastewater Treatment Plant, Verquigneul, France

NOEUX LES MINES NELLE SE is a wastewater treatment plant located in Verquigneul, a commune in the Pas-de-Calais department of northern France. The plant serves a population of around 16,350 people, placing it within the medium agglomeration category under French and European regulations. It operates within the Hauts-de-France region, an area with a mix of urban and industrial activity. As a French wastewater facility, the plant operates under the European Union's 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 discharge enters sensitive areas, which are common in the region due to its dense river network and proximity to the North Sea. The plant's treatment processes are designed to meet these regulatory standards, ensuring compliance with national and EU water quality goals. The plant's treated effluent is discharged into local watercourses that ultimately drain into the North Sea via the Lys and Scheldt river basins. This region supports diverse aquatic life and is important for migratory fish species. The plant plays a key role in protecting downstream water quality, particularly in the context of the region's agricultural and industrial activities.

The plant discharges into the local river system, which flows into the Lys River, a tributary of the Scheldt. The Scheldt basin drains into the North Sea, a sensitive marine environment that supports fisheries and biodiversity. The region's waterways are ecologically significant, providing habitat for species such as Atlantic salmon and European eel. The plant's operations help reduce nutrient and pollutant loads, contributing to the health of these downstream ecosystems.
