FLINT — The city of Flint will reconnect to the Detroit water system and stop using the Flint River as its water source amid concerns about lead contamination. 

Gov. Snyder announced the plan Thursday, which involves paying for nine months of water from the Detroit Water and Sewerage Department. The department will treat water from Lake Huron and it should begin flowing through Flint’s water system in two weeks or less. 

Snyder said the cost to resume service with Detroit would be about $12 million. He is asking the state legislature to approve a $6 million grant from the state. The Mott Foundation has pledged $4 million and the city of Flint will contribute $2 million. 

An additional $4 million will be requested from the state to address immediate lead issues, including more testing of children in Flint schools. In state tests this week, three school buildings were above the federal limits for lead in drinking water. One school’s lead level was more than six times the limit.

“This effort today is the result of people coming together to solve a problem,” Snyder said in a statement. “I appreciate Detroit’s willingness to reconnect with Flint, the Mott Foundation’s generous commitment and the dedication of all parties to come together to protect Flint families and children.”

Last week Snyder said reconnecting with Detroit’s water system was an option, but focused on providing residents with filters and free water testing. 

Thursday’s announcement followed a recommendation by Flint’s Technical Advisory Committee to change the city’s drinking water source because of rising levels of lead in the water and blood of children and infants in the area. The state confirmed last week a recent study at Hurley Children’s Hospital that found increased lead levels in blood tests for children living in two Flint ZIP codes.

The city of about 100,000 residents started using the Flint River as its water source in 2014, after a state-appointed emergency manager ruled out a deal to keep buying water from Detroit.
