The City of Twin Falls has issued a press release, lifting the Water Advisory for north Twin Falls.

The City of Twin Falls has received approval from the Department of Environmental Quality to lift the Water Advisory as of 7 a.m. Saturday, March 12. All residents and businesses in Twin Falls, including those located north of Addison Avenue who were affected by the Advisory, may drink city potable water without boiling, filtering, or otherwise treating it.

The Advisory had been in effect since 10 a.m. Friday, March 12, when contractors working on the Cheney Drive Extension Project struck a water main near the intersection of North College Road and Frontier Road. When waterlines lose pressure, they run the risk of back-flowing and siphoning substances into the potable water system.

City water systems were quickly initiated during the waterline break to increase pressure on the pipes and to isolate the breach, and the City did not believe there was any immediate risk to the public. However, the City wanted to ensure that that was no risk of residents becoming ill through contaminated water, so it enacted the Water Advisory to allow for stringent testing of City water, as according to DEQ rules.

A Water Advisory is a precautionary measure that encourages water users to boil, filter, or otherwise treat water before drinking. Or use bottled water. It is not a Boil Order, which requires users to treat drinking water and for City’s to take additional measures until testing can be completed.

During the Water Advisory, city workers gathered more than a dozen water samples from waterlines and sent them to an independent lab for analysis. All tests verified that City water continued to be safe to drink during the disruption.

The City of Twin Falls appreciates citizens’ patience during the Water Advisory, as it resulted in a significant inconvenience for residents and businesses. However, please understand that these rules are in place to protect everyone from illness.

Because of the high number of calls, messages will be returned within 20 minutes.
