FLINT, Mich. (NBC) -- Correction: News 10 incorrectly stated earlier that the city of Flint had replaced 18,000 service lines to help alleviate the city's water crisis.
Those 18,000 pipes have been excavated for inspection. Of that 18,000, about 7,700 have actually been replaced.
Flint Mayor Karen Weaver held a news conference Tuesday to provide an update to her FAST Start initiative and water service line replacement effort.
Weaver said the city has replaced about 7,700 tainted service lines ahead of schedule. More than 18,000 have been excavated for inspection.
Weaver also noted that residents should still rely on filtered and bottled water, despite the progress.
"The water is testing better, but with the construction in the city, we don't want to risk shaking a lead pipe loose," Weaver told a reporter.
Weaver said they'd like to be done replacing pipes by July.
FAST Start's goal has been to have all of Flint's approximately 18,000 tainted service lines replaced by 2020. According to the mayor's office, since the FAST Start initiative began in March 2016, crews from area companies have completed excavation at 18,313 homes. As of April 2018, 9,480 homes have been checked.
The mayor's office said according to reports from contractors, crews have identified copper service lines at a total of 8,001 homes, 1,479 homes have been identified as having lead and/or galvanized service lines. Overall, to date, service lines to 7,707 homes have been identified as lead and/or galvanized and have been replaced, including 1,479 homes found this year.
The efforts are a part of Mayor Karen Weaver’s plan to determine if water service lines are made of copper, and replace service lines made of lead and galvanized steel.
To be eligible for service line replacements, residents must have an active water account. They also must sign a consent card giving permission for the work to be done (consent cards are being delivered to residents). In rental homes, both the owner and the tenant must sign consent cards. Residents are urged to sign the consent cards as soon as possible, so crews working in their neighborhood can replace their service line.
It was back in 2014 when Flint changed water sources resulting in lead contamination and other issues while the city was under state management. The water was not deemed safe to drink by federal standards until January 2017. Still, specific pipelines to homes and building had to be replaced.
