Overview
BULLY LES MINES Mazingarbe is a municipal wastewater treatment plant serving approximately 73,350 people in Mazingarbe, Hauts-de-France, France. The plant operates under the EU Urban Waste Water Treatment Directive.
BULLY LES MINES Mazingarbe is a wastewater treatment plant located in Mazingarbe, a commune in the Pas-de-Calais department of the Hauts-de-France region in northern France. The plant serves a population of around 73,350, placing it in the medium-to-large agglomeration category under EU classification. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), agglomerations of this size are required to provide at least secondary treatment, with more stringent tertiary treatment if discharging into sensitive areas. The plant's treatment process and capacity details are not publicly available, but the regulatory framework ensures compliance with national and EU standards for effluent quality. The plant discharges treated wastewater into the local water system, which ultimately drains into the North Sea via the Deûle River and the Scheldt basin. This region is characterized by industrial and urban development, and the plant plays a key role in protecting downstream water quality and aquatic ecosystems.
Environmental context
The plant's treated effluent flows into the Deûle River, a tributary of the Scheldt, which drains into the North Sea via the Western Scheldt estuary. The downstream environment supports diverse aquatic life and is an important migratory corridor for fish. The region's industrial history means careful wastewater management is essential to prevent nutrient enrichment and contamination of coastal waters.
