DOULLENS Wastewater Treatment Plant, Doullens, Hauts-de-France, France

The DOULLENS wastewater treatment plant is located in Doullens, a commune in the Somme department of Hauts-de-France, France. It serves a population of approximately 8,274 people, classifying it as a small to medium agglomeration under EU regulations. The plant is situated inland, away from the coast, and its treated effluent likely discharges into a local watercourse within the Somme river basin. As a French wastewater facility, DOULLENS 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 appropriate treatment to meet water quality standards for the receiving environment. The plant is expected to comply with national regulations that implement the directive. The plant's discharge ultimately reaches the Somme River, which flows into the English Channel. The Somme basin supports diverse aquatic life and is an important ecological corridor. Proper treatment at DOULLENS helps protect downstream water quality and the sensitive coastal environment of the Baie de Somme, a significant area for migratory birds and marine life.

The DOULLENS plant discharges into the Somme River basin, which flows through the Hauts-de-France region before reaching the English Channel. The Somme River and its estuary support diverse aquatic ecosystems, including fish populations and migratory birds. The Baie de Somme is an ecologically sensitive area known for its rich biodiversity, including seals and numerous bird species. Effective wastewater treatment is crucial to prevent nutrient pollution and maintain the health of this downstream environment.
