Contractors will be out in Flint neighborhoods as part of the latest effort to replace old lead and galvanized steel water lines amid the city’s crisis with lead-tainted water. A kickoff for the latest phase of the Fast Start program was Friday. Mayor Karen Weaver says it’ll result in the replacement of service lines at 200-250 homes. She says contractors will be out in neighborhoods to seek permission from residents. This fall, her office says the next phase of the replacement program that started in March will cover 5,000 additional homes. The project has replaced lines at 33 homes during the first phase. Over 18 months, lead leached from old pipes into Flint’s water supply when the city used water from the Flint River. The water wasn’t treated for corrosiveness.
