UPDATE, 3:24 p.m. Wednesday: The boil order in effect in Grayslake is expected to remain in effect for the next 36-48 hours, village officials said in a press release issued at 3:14 p.m. Wednesday.
Officials said the village’s water system lost pressure just after 12:30 p.m.
“A preliminary investigation revealed that a telemetry system malfunction, possibly caused by the extreme cold temperatures experienced over the last three days, led to the loss of pressure,” officials said in the press release. “Immediately upon learning of the malfunction, village crews responded by overriding the automatic operating system and manually pumping water back into the system. Normal water pressure was restored in less than 30 minutes.”
The boil order was issued in accordance with Illinois Environmental Protection Agency regulations, officials said.
“During the boil order, bottled water should be used for drinking, cooking, washing fresh fruits and vegetables, hand washing, and tooth brushing. If bottled water is not available, the affected tap water should be used for these purposes only after it has been boiled for five minutes,” officials noted.
