Overview
PONT DE ROIDE wastewater treatment plant serves Bourguignon in Bourgogne-Franche-Comté, France. It treats wastewater from approximately 6,900 people under the EU Urban Waste Water Treatment Directive.
PONT DE ROIDE is a wastewater treatment plant located in Bourguignon, within the Montbéliard area of Doubs, Bourgogne-Franche-Comté, France. The facility serves a population of approximately 6,900 residents, classifying it as a small to medium agglomeration under French and EU regulations. As a plant operating in France, it falls under the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The directive also requires appropriate treatment before discharge into freshwater bodies to protect water quality and ecosystems. The plant discharges treated effluent into the local watershed, which ultimately drains into the Doubs River, a tributary of the Saône, then the Rhône, and finally the Mediterranean Sea. This downstream connection highlights the plant's role in protecting the broader Rhône basin and Mediterranean coastal waters from nutrient pollution and other contaminants.
Environmental context
The treated effluent from PONT DE ROIDE enters the local watercourse, which flows into the Doubs River, a key tributary of the Saône River. The Saône joins the Rhône, which discharges into the Mediterranean Sea. This watershed supports diverse aquatic life and is an important ecological corridor. The plant's operations help maintain water quality in this sensitive river system, reducing nutrient loads that could otherwise contribute to eutrophication in downstream waters.

The treated effluent is discharged into the local watercourse, which flows into the Doubs River, part of the Rhône basin that ultimately reaches the Mediterranean Sea.
As a French plant, it operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations over 2,000 population equivalent.
For agglomerations of this size, the EU directive mandates secondary treatment (biological treatment) to reduce organic matter and suspended solids, with possible additional nutrient removal if discharging into sensitive areas.
