ANDOY Comognes Wastewater Treatment Plant, Namur, Belgium

ANDOY Comognes is a former wastewater treatment plant located in the Andoy district of Namur, in the Walloon region of Belgium. The plant served a small population of 371 people and was designed to handle up to 600 m³/day, with an average discharge volume of 66.32 m³/day. It operated at secondary treatment level before being closed. As a secondary treatment facility, ANDOY Comognes would have met the requirements of the EU Urban Waste Water Treatment Directive (91/271/EEC), which mandates secondary treatment for agglomerations of this size. The plant's closure may reflect consolidation of wastewater services in the Namur area, where larger regional facilities now manage treatment. The plant's discharge likely entered a local watercourse within the Meuse River basin, which flows through Namur and eventually drains into the North Sea. The Meuse supports diverse aquatic life and is an important ecological corridor in the region. The closure of this plant may have reduced local discharge impacts, with wastewater now routed to a larger facility with potentially higher treatment standards.

The plant discharged into a local watercourse within the Meuse River basin. The Meuse flows north through Belgium and the Netherlands before emptying into the North Sea. The river supports diverse aquatic life and is an important migratory corridor for fish. The closure of this plant likely reduced nutrient and pollutant loads to the local watershed, improving water quality in the downstream environment.
