ROYE SE Wastewater Treatment Plant, Roye, Hauts-de-France, France

ROYE SE is a municipal wastewater treatment plant located in Roye, a commune in the Somme department of the Hauts-de-France region, northern France. The plant serves a population of around 6,684 residents, placing it in the small agglomeration category under French and EU regulations. As a French wastewater facility, ROYE SE operates under the EU Urban Waste Water Treatment Directive (91/271/EEC), which requires secondary treatment for agglomerations of this size discharging into freshwater. The regulatory framework ensures compliance with national standards for effluent quality. The plant discharges treated water into the local watershed, which ultimately drains into the Somme River and then the English Channel. The Somme River basin supports diverse aquatic life and is an important ecological corridor in the region. The plant's operations contribute to protecting the water quality of the Somme and its downstream environment.

The treated effluent from ROYE SE enters the local watercourse, which flows into the Somme River, a major river in northern France. The Somme River basin is ecologically significant, supporting diverse fish populations and migratory birds. The river discharges into the English Channel near the Baie de Somme, an area of high ecological value. The plant's treatment helps maintain water quality in this sensitive downstream environment.
