The project involved the construction of a potable water treatment plant in the west of the town of Sainte-Marie. The new plant, which draws water from the Chaudière River, has a capacity of 13,360 m3 per day and has a complete treatment line involving a membrane filtration technology.
Other work includes:
- Setting up basins;
- Setting up pumping stations; and
- Installing ozonation and disinfection systems.
To connect the waterworks and sewage systems to the plant, the project involved the installation of a water line covering approximately 230 metres to deliver treated water to the St-Joseph reservoir, the establishment of a domestic sewer back-up of approximately 310 metres, and various complementary works.
The project included 3000 m3 of cast concrete. The concrete used contained an admixture that caused some difficulties. Instead of hardening in an hour and a half, it took more than 25 hours. Pomerleau had to be flexible and review the concreting sequence in order to not pour near newly-cast concrete and risk causing cracks.
Sainte-Marie's mayor, Mr. Harold Guay, welcomed the completion of this project, which was a priority for the municipality's development. It has improved community infrastructure from a sustainable development standpoint and contributes to the well-being of the population.
