Overview
Neauphlette-Breval wastewater treatment plant serves 2,130 people in Neauphlette, Île-de-France, France. It provides advanced treatment and discharges treated effluent into the local watershed.
The Neauphlette-Breval wastewater treatment plant is located in Neauphlette, a commune in the Yvelines department of Île-de-France, France. The facility serves a population of approximately 2,130 residents and operates with a designed capacity of 5,000 cubic meters per day, indicating it is sized to accommodate future growth. As a small agglomeration, it is subject to French regulations transposing the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires appropriate treatment for discharges into sensitive areas. The plant employs advanced treatment processes, going beyond the secondary treatment standard to achieve higher levels of pollutant removal. This is particularly important for protecting the receiving water bodies in the Seine-Normandy basin. The plant discharges a daily volume of about 380 cubic meters of treated wastewater, well within its design capacity. The treated effluent from the Neauphlette-Breval plant ultimately flows into the Seine River via local tributaries, contributing to the overall water quality management of the Seine basin. The Seine River is ecologically significant, supporting diverse aquatic life and serving as a major water resource for the Paris region. The plant's advanced treatment helps reduce nutrient loads and protect downstream ecosystems.
Environmental context
The plant discharges into the local watershed that drains into the Seine River, which flows through Paris and eventually into the English Channel. The Seine basin supports a variety of fish species and is an important ecological corridor. Advanced treatment at this plant helps minimize nutrient pollution, protecting water quality in the river and its estuary.
