City officials say that Friday at 2 p.m. is the earliest the system-wide advisory will be lifted in Saline.
A large water main break early Thursday caused a city-wide boil water advisory after an earlier drop in pressure.
Thursday afternoon, Jeff Fordice, Director of Public Works, sent out a press release stating that the water main repair had been completed, and that the Department of Public Works is currently filling and flushing the main.
"The Henry Street water tower is full and water pressure on the south side of the city is back to normal," the statement read. "The Industrial Drive water tower is at approximately 50 percent of its normal operating level and as a result, some parts of the north side are still experiencing reduced pressure. The tower should be full this evening and pressures will return to normal throughout the city."
According to the city, the water main broke at Michigan and Maple.
Businesses along the affected water main will be under boil water advisory longer than the rest of the city, according to the statement. A timeline has not been given for when those customers will no longer be under advisory.
