An official says Flint's plans to start providing drinking water to city customers from the Flint River have been delayed amid work on a disinfectant system.
The Michigan Department of Environmental Quality says there's still construction work going on at the disinfectant system at the water treatment plant. The city had planned the switch Monday.
Steve Busch with the DEQ says it will take "a couple of more days."
City officials last week opened an intake pipe from the Flint River. The city plans to use water from the Flint River instead of relying on the flow supplied by the Detroit Water and Sewerage Department.
The move is a temporary measure until the Karegnondi Water Authority completes its pipeline in 2016 from Lake Huron.
