DOUE la grande Allee is a wastewater treatment plant located in Doué-en-Anjou, within the Maine-et-Loire department of Pays de la Loire, France. The facility serves an estimated population of 9,500, classifying it as a small to medium agglomeration under French regulations. As a French plant serving fewer than 10,000 people, it is subject to the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment before discharge. French plants of this scale typically employ secondary biological treatment to meet national water quality standards. The plant discharges treated effluent into local waterways that ultimately drain into the Loire River basin, one of France's major river systems. The Loire flows into the Atlantic Ocean, supporting diverse aquatic ecosystems and serving as a critical water resource for the region.
Environmental context
The plant's treated effluent enters the local watershed, which is part of the Loire River basin. The Loire River flows through the Pays de la Loire region before reaching the Atlantic Ocean. This basin supports diverse aquatic life, including migratory fish species, and is ecologically sensitive due to agricultural runoff and urban pressures. Proper treatment at this plant helps protect downstream water quality.
