MONTMEYRAN (26)

Invert rinsing via vacuum flushing

Storage basin

As the treatment plant of the city of Montmeyran was no longer able to meet the environmental constraints defined by law, the community of greater Valence decided to do away with it and to connect the wastewater network to the Portes-Lès-Valence plant. In order to store the combined overflows during storms, an above-ground storm water basin was created in place of the old plant.The sludge deposited on the invert is rinsed by a flushing system set up by Saint Dizier Environnement.
