Overview
GAUCHY wastewater treatment plant serves Gauchy, Hauts-de-France, France, with a population equivalent of 96,200. It operates under the EU Urban Waste Water Treatment Directive, which mandates secondary treatment for agglomerations of this scale.
The GAUCHY wastewater treatment plant is located in Gauchy, a commune in the Aisne department of the Hauts-de-France region, northern France. The facility serves a population equivalent of 96,200, classifying it as a large agglomeration under EU regulations. Its address is Chemin de la Biette, Gauchy, Saint-Quentin, Aisne, Hauts-de-France. As a French wastewater facility serving over 15,000 population equivalent, GAUCHY is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC). This directive requires secondary biological treatment for all discharges from agglomerations of this size, with additional tertiary treatment if the receiving waters are designated as sensitive areas. The regulatory framework ensures compliance with European standards for organic matter and nutrient removal. The plant discharges treated effluent into the local watershed, which ultimately drains into the Somme River basin. The Somme River flows westward into the English Channel, supporting diverse aquatic ecosystems and providing critical habitat for migratory fish species. The Hauts-de-France region features a temperate maritime climate with moderate rainfall, influencing the hydrological regime of the receiving waters.
Environmental context
The GAUCHY plant discharges into the Somme River basin, which flows into the English Channel. The Somme River supports diverse aquatic life and is an important migratory corridor for fish species such as Atlantic salmon and eel. The watershed includes agricultural and urban areas, and the plant's nutrient removal performance is critical to preventing eutrophication in downstream waters.
