2019 Water Main Cleaning Program

May 20, 2019

This year’s water main cleaning program, where crews flush water mains, began on Wednesday, May 15.  We do this to preserve the quality of water as it passes from our drinking water treatment plant to customer’s taps. Crews use a uni-directional flushing technique, which involves hydrant and valve operations to direct the flow of water to “scour” the inside of the pipes, removing sediment. 

This year we plan to clean about 500 kilometres of water mains in north and south areas of the City. We have detailed maps of the areas to be cleaned this year. These are on our website at winnipeg.ca/wmc

City crews will be flushing water mains seven days a week from 8 a.m. to 11 p.m. until we are complete, which is expected before the end of September.  We do additional water quality monitoring throughout the program. 

I will keep you informed of when streets in the ward will be cleaned and you can also find more program details at: winnipeg.ca/wmc
