Addition of a manganese treatment at the drinking water production plant

completed

This Project consists of adding a manganese treatment system to the existing drinking water production plant in the Town of Saint-Joseph-de-Lac, Quebec. Currently, the drinking water treatment station only has one component of water treatment, which involves sodium hypochlorite. Total manganese concentrations in raw water frequently and significantly exceed, almost three (3) times, the value recommended by Health Canada. Expansion works at the current station is planned to allow the treatment of manganese while using two (2) biological pressure filters, operated in parallel. In addition, an underground tank will be installed to receive the wastewater that will come from the filters. Part of the site will have to be cleared to allow the station to be enlarged, since it is located in a wooded area of the park. This Project aims to upgrade drinking water treatment infrastructure.
