SAINT MARS LA JAILLE Bd de la Ferronnay is a wastewater treatment plant located in Saint-Mars-la-Jaille, a commune in the Loire-Atlantique department of the Pays de la Loire region, France. The plant serves a population of approximately 10,617, classifying it as a medium-sized agglomeration under EU regulations. As a French facility, the plant operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The directive also mandates more advanced treatment if the receiving waters are designated as sensitive areas. It is expected to meet the regulatory standards for its population tier. The plant discharges treated wastewater into the local watershed, which ultimately drains into the Loire River and then the Atlantic Ocean. The Pays de la Loire region features a network of rivers and estuaries that support diverse aquatic life and are important for regional ecology. The plant's operations contribute to protecting water quality in this sensitive downstream environment.
Environmental context
The plant's treated effluent enters the local water system, which flows into the Erdre River, a tributary of the Loire. The Loire River is one of France's longest rivers and empties into the Bay of Biscay (Atlantic Ocean). The downstream environment includes ecologically significant wetlands and estuaries that support migratory fish species and diverse bird populations. Maintaining high water quality in this watershed is critical for both biodiversity and human uses such as fishing and recreation.
