Update: Tooele drinking water is now safe, officials say.

Tooele City was warning residents in its southeast neighborhoods not to drink city water on Saturday due to a break in the city’s water storage tank.

“The City is working hard to collect samples, flush the system, and clean the tank. Contamination risk is currently unknown,” city officials posted on Facebook.

The break was discovered on Saturday during a daily inspection, city officials wrote.

The do-not-drink order was for city water supplied south of Vine Street and east of Main Street. Anyone in that area should bottled water for drinking, making ice, brushing teeth, washing dishes and preparing food.

“We encourage you to purchase your own bottled water, but if you are not able to do so bottled water is available at the Tooele City Police Department,” the city’s notice stated.

Anyone who fears they may have been sickened by the water should seek medical advice, according to the city’s notice.

The water is being tested; city officials expected to learn by Sunday morning whether the water was contaminated.
