Overview
Jean Maleze is an advanced wastewater treatment plant in Sauveterre-Saint-Denis, Nouvelle-Aquitaine, France. It serves approximately 4,100 people and has a designed capacity of 30,000 m³/day.
Jean Maleze is an advanced wastewater treatment plant located in Sauveterre-Saint-Denis, within the Lot-et-Garonne department of Nouvelle-Aquitaine, France. The plant serves a population of around 4,100 and is designed to handle up to 30,000 m³ per day, indicating capacity for future growth or seasonal variations. The plant employs advanced treatment processes, which go beyond secondary treatment to remove nutrients and other pollutants. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), France requires advanced treatment for discharges into sensitive areas. Although the specific receiving water body is not named, the plant's inland location suggests it discharges into a river or stream within the Garonne basin. The treated effluent likely flows into the Garonne River system, which drains into the Gironde estuary and ultimately the Atlantic Ocean. This watershed supports diverse aquatic life and is important for regional water quality. The plant's advanced treatment helps protect downstream ecosystems from nutrient pollution.
Environmental context
The plant discharges into a tributary of the Garonne River, which flows through southwestern France to the Gironde estuary and the Atlantic Ocean. The Garonne basin supports diverse aquatic habitats and is a critical corridor for migratory fish species. Advanced treatment at this plant helps reduce nutrient loads that could otherwise contribute to eutrophication in the estuary and coastal waters.
