A precautionary boil water notice has been issued for the Cave Rock Water System in Douglas County. The Douglas County Manager’s Office says the notice is due to treatment plant shutdown, computer failure, and a data logging loss at the Cave Rock Water Treatment Plant. The boil water notice will be in effect until bacteriological samples come back clean. The Douglas County Manager’s Office says “the boil water notice is only precautionary at this time but we are taking the proper steps to ensure the safety of our residents.”
