CLINTON — A precautionary boil order has been ordered for the entire city of Clinton.

At 2 p.m., a 16-inch water main break was reported in the 1400 block of 13th Avenue South. Iowa American Water, which began calling potentially affected residents a short time after, at first ordered the precautionary boil order for residents in the affected area. The company later reported that it has impacted the entire city, calling for a precautionary boil order for safety.

Residents may see low to no water pressure and/or cloudy water — the repair time is unknown for the time being. To use water from the tap, bring it to a boil for at least one minute before drinking or cooking until further notice. Iowa American Water stated the water is OK for bathing, washing and other common uses.

The main break is isolated, and by 3:30 p.m. crews were excavating for repairs. Residents from the 1200 block to 1600 block of 13th Avenue South will not have water service restored until repairs are complete; this is the area that has been isolated. Repairs will take around 10 hours to complete, according to Iowa American Water, due to the size and extent of the break, as well as weather conditions.

The precautionary boil advisory is held in accordance with regulations from the Iowa Department of Natural Resources and will be in effect for at least 24 hours or until the water quality tests are satisfactory under state and federal regulations.
