Overview
SAINT LAURENT DE LA PREE ZI is a secondary treatment plant in Saint-Laurent-de-la-Prée, Nouvelle-Aquitaine, France, serving a small population of 25 with a designed capacity of 50 m³/day.
SAINT LAURENT DE LA PREE ZI is a wastewater treatment plant located in Saint-Laurent-de-la-Prée, a commune in the Charente-Maritime department of Nouvelle-Aquitaine, France. The plant serves a small population of 25 people and has a designed capacity of 50 m³/day, with an actual discharge volume of 4.46 m³/day, indicating low utilization. It is situated near the coast, within 10 km of the Atlantic Ocean. As a secondary treatment facility, the plant provides biological treatment to reduce organic matter and suspended solids. Under the EU Urban Waste Water Treatment Directive (91/271/EEC), small agglomerations like this are generally required to have appropriate treatment, though secondary treatment is standard for discharges to coastal waters. The plant's capacity and population served suggest it handles a very low flow, typical of a small industrial or rural zone. The plant discharges treated effluent into the local watershed, which ultimately drains into the Atlantic Ocean via the Charente River estuary. The nearby Pertuis d'Antioche and the Île d'Oléron are ecologically sensitive areas supporting diverse marine life, including migratory fish and seabirds. The plant's coastal location means its discharge must comply with regulations to protect the marine environment from nutrient pollution and other impacts.
Environmental context
The plant is located in the Charente-Maritime region, within the watershed of the Charente River, which flows into the Atlantic Ocean via the Pertuis d'Antioche. This coastal area supports diverse marine ecosystems, including seagrass beds and shellfish fisheries, which are sensitive to nutrient enrichment from wastewater discharges. The proximity to the coast (within 10 km) means that treated effluent can quickly reach the marine environment, necessitating effective treatment to minimize ecological impact.
