The buffer basin of the Mirebeau wastewater treatment plant, designed to handle effluents from 15,000 population equivalents, recently underwent a comprehensive cleaning. This operation was made possible by work carried out to isolate the basin while maintaining effluent circulation, a first since its construction in 2000.
A specialized company intervened after a week of draining, removing a total of 47 tons of sand accumulated over the years. The intervention also included a civil engineering assessment of the structure.
This basin will be preserved as part of the project to build a new activated sludge wastewater treatment plant, scheduled for commissioning by 2028.
