SANCEY LE GRAND is an advanced wastewater treatment plant located in Sancey, within the Bourgogne-Franche-Comté region of eastern France. The facility serves a population of approximately 2,400 residents and has a designed capacity of 3,000 m³/day, with an actual discharge volume of 428.16 m³/day. As an advanced treatment plant, it provides a higher level of pollutant removal than secondary treatment, which is typical for facilities in sensitive areas under the EU Urban Waste Water Treatment Directive (91/271/EEC). The directive requires appropriate treatment for agglomerations of this size to protect receiving water bodies. The plant's treated effluent is discharged into local waterways that ultimately drain into the Doubs River, a tributary of the Saône, which flows into the Rhône and then the Mediterranean Sea. This connection to a major European river system underscores the plant's role in maintaining downstream water quality.
Environmental context
The plant discharges into the Doubs River basin, part of the Rhône-Mediterranean watershed. The Doubs River supports diverse aquatic life and is an important ecological corridor in the Jura region. Downstream, the Saône and Rhône rivers flow through agricultural and urban areas before reaching the Mediterranean Sea, making nutrient and pollutant control critical for coastal water quality.
