Overview
SAINT LAURENT DE LA PREE Roche is a secondary treatment plant in Saint-Laurent-de-la-Prée, Nouvelle-Aquitaine, France. It serves a small population of 27 and discharges 4.82 m³/day of treated wastewater.
SAINT LAURENT DE LA PREE Roche is a municipal wastewater treatment plant located in Saint-Laurent-de-la-Prée, a commune in the Charente-Maritime department of Nouvelle-Aquitaine, southwestern France. The plant serves a very small population of 27 people, reflecting its role in a rural or peri-urban setting near the Atlantic coast. The plant provides secondary treatment, which is the standard biological treatment required under the EU Urban Waste Water Treatment Directive (91/271/EEC) for agglomerations of this size. With a designed capacity of 80 m³/day and a current discharge volume of 4.82 m³/day, the plant operates well below its capacity, indicating ample headroom for future growth or seasonal variations. The treated effluent is discharged into the local watershed, which ultimately drains into the Atlantic Ocean via the Charente River estuary. The plant's proximity to the coast (within 10 km) means its discharge contributes to the nutrient and pollutant load entering the marine environment, making effective treatment essential for protecting coastal water quality and marine ecosystems.
Environmental context
The plant discharges into the local hydrological network that feeds into the Charente River, which flows into the Pertuis d'Antioche strait and the Bay of Biscay (Atlantic Ocean). This coastal zone supports diverse marine life, including nursery habitats for fish and migratory bird populations. The proximity to the coast underscores the importance of secondary treatment in reducing organic and nutrient pollution that could contribute to eutrophication in the sensitive estuarine and coastal waters.
