(FLINT) -- Flint officials have rejected an offer to keep getting water service from Detroit and instead will participate in a pipeline project to tap Lake Huron. Flint officials announced their decision Tuesday. The state of Michigan last week approved Flint's plans, subject to review of a final offer from the Detroit Water and Sewerage Department. Detroit will supply Flint for the next three years during construction of the Karegnondi Water Authority project. The authority includes representatives from Flint, Lapeer, and Genesee, Lapeer and Sanilac counties. Flint plans to get millions of gallons of water per day from Lake Huron, pipe it to Flint for treatment and then sell it to city customers. The intake pipeline will extend nearly two miles into Lake Huron in Sanilac County's Worth Township. Construction on the pipeline project is expected to take a year to complete and cost around $35 million. The pump station will be located in the woods on the west side of M-25. A total cost for the project is between $270 and $300 million with a completion date set sometime in 2015. Detroit water officials say they could lose $22 million if Flint leaves its system and other customers could see higher rates.
