Early next week, officials plan to begin a temporary change to Flint's drinking water source.
Flint’s tap water will soon become a mix of water from the Great Lakes Water Authority (GLWA) and Genesee County.
GLWA is Flint’s primary drinking water source. The county system is Flint’s backup. Lake Huron is the source for both, with the county's water coming via the Karegnondi pipeline.
The county pipeline to Flint’s water system was flushed for testing over the weekend with no bacteria detected after multiple testing periods.
The plan is that early next week, Flint’s water source will begin an incremental temporary switch to the county system to allow the GLWA pipeline to undergo some repairs.
Officials say additional monitoring will take place during the incremental increase, valve replacement work on the primary water delivery system (GLWA) and during all other major infrastructure projects. Monitoring results are posted on the EPA’s “Taking Action on Flint Water” website at www.michigan.gov/flintwater.
Flint’s water system was damaged back in 2014 by the ill-fated decision to take water from the Flint River that wasn’t properly treated, exposing city residents to high levels of lead and other contaminants.
