The Luzech wastewater treatment plant is located in the commune of Luzech, in the Lot department of Occitanie, southern France. It serves a population of approximately 2,578 people, placing it in the small agglomeration category under French regulations. The plant provides advanced treatment, which goes beyond the secondary treatment required by the EU Urban Waste Water Treatment Directive for agglomerations of this size. The facility has a designed capacity of 2,500 m³/day and currently treats an average daily flow of 459.91 m³/day, indicating ample reserve capacity. The treated effluent is discharged into the local watershed, which ultimately drains into the Lot River, a major tributary of the Garonne River. The Garonne flows into the Gironde estuary and then the Atlantic Ocean. The plant plays a key role in protecting the Lot River and downstream aquatic ecosystems from nutrient pollution and organic loading.
Environmental context
The plant discharges into the Lot River basin, which flows through the Occitanie region before joining the Garonne River. The Garonne estuary and the Gironde are ecologically important areas supporting diverse fish species, including migratory sturgeon and salmon. Advanced treatment at this plant helps reduce nutrient loads that could contribute to eutrophication in the downstream river and estuarine environments.
