Overview
NOLAY wastewater treatment plant serves Cirey-lès-Nolay in Bourgogne-Franche-Comté, France. It provides secondary treatment for a population of 2,030 with a designed capacity of 1,700 m³/day.
The NOLAY wastewater treatment plant is located in Cirey-lès-Nolay, a commune in the Côte-d'Or department of Bourgogne-Franche-Comté, France. It serves a population of approximately 2,030 people and has a designed capacity of 1,700 m³/day, with an actual discharge volume of 362.15 m³/day, indicating it operates well below its capacity. As a secondary treatment facility, the plant meets the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations with a population equivalent between 2,000 and 10,000. The plant's treatment process likely involves biological treatment to reduce organic matter and suspended solids before discharge. The plant discharges treated effluent into a local watercourse that ultimately drains into the Saône River, a major tributary of the Rhône. This contributes to the water quality management of the Rhône basin, which supports diverse aquatic ecosystems and is an important water resource for the region.
Environmental context
The treated effluent from NOLAY plant flows into a local stream that joins the Saône River, which then merges with the Rhône River before reaching the Mediterranean Sea. The Rhône basin is ecologically significant, supporting diverse fish populations and migratory species. The plant's secondary treatment helps protect downstream water quality in this sensitive watershed.
