The Lacapelle-Marival wastewater treatment plant is located in the commune of Lacapelle-Marival in the Lot department of Occitanie, southern France. It serves a population of approximately 2,733 residents, classifying it as a small agglomeration under French and EU regulations. The plant provides secondary treatment, which is the minimum standard required by the EU Urban Waste Water Treatment Directive (91/271/EEC) for freshwater discharges from agglomerations of this size. With a designed capacity of 3,500 m³/day and an average daily flow of 487.56 m³/day, the plant operates well below its capacity, indicating room for future growth or seasonal variations. The treated effluent is discharged into a local watercourse that ultimately flows into the Lot River, a tributary of the Garonne, which drains into the Atlantic Ocean via the Gironde estuary. The plant plays a key role in protecting the Lot River and downstream aquatic ecosystems from nutrient pollution and pathogens.
Environmental context
The plant discharges into a small stream that feeds the Lot River, part of the Garonne basin. The Lot River supports diverse aquatic life and is used for recreation and agriculture. Downstream, the Garonne estuary is an ecologically sensitive area important for migratory fish such as salmon and eels. Secondary treatment reduces organic load and suspended solids, helping to maintain water quality in this inland watershed.
