Planned maintenance will take place at the Mattagami Water Pollution Control Plant to facilitate draining, cleaning, and refilling of the chlorine contact tank. This work is required to remove the solids on the bottom of the tank and to remove the growth of algae and moss on the tank walls. While this will temporarily reduce the chlorine contact time, chlorine will continue to be added to the final effluent, and we do not expect significant impacts on the final disinfection process. The Ministry of the Environment, Conservation and Parks have been notified, and samples will be collected.
