Lake County Public Works (LCPW) will be conducting leak detection services as part of our watermain infrastructure assessment and maintenance program. Work will begin in October on the Wildwood water system and the Vernon Hills water system. Leaks are detected by listening to above ground structures with special equipment and you may see work crews in your yard during the inspection. During the detection process water service should not be interrupted. If you have any concerns feel free to contact the project engineer or inspector. To report a watermain leak on a County water system during normal business hours call 847-377-7500 and dial 0. To report watermain breaks after 5 p.m. call the Lake County Sheriff at 847-377-7188.
