Water Main Cleaning and Lining
Of the 1060 miles of water main pipes in Minneapolis, 760 miles are constructed of unlined cast iron. Cast iron was the standard until the 1970’s and it was manufactured unlined. All pipes installed since the 1970’s are made of ductile iron that comes from the factory with a cement lining on the inside. With time, unlined cast iron mains build up mineral deposits that restrict the flow and can result in discolored water. Rusty water meets all regulatory requirements but is aesthetically displeasing.
This water main cleaning and lining project is to scrape the rust out of the pipes and install a potable water grade lining that keeps that will prevent new rust from forming. This will extend the life of the pipes as well as improve the water appearance and flow of water through the pipes.
Because the water main must be empty for the work, each building that taps into the water mains that are being worked on will be supplied with a temporary water line. The water in the temporary pipes will be sampled throughout the project to make sure that the water meets drinking water standards.
This work will not be assessed to the property.
The traffic impact for these projects is minimal. Learn more about project locations below.
