Libertyville

The Village obtains its municipal water from the Central Lake County Joint Actions Water Agency (CLCJAWA), an inter-governmental cooperative serving multiple communities including: Grayslake, Gurnee, Lake Bluff, Libertyville, Lindenhurst, Mundelein, Round Lake, Round Lake Beach, Round Lake Heights, Round Lake Park and Lake County representing unincorporated areas of Knollwood and Roundout, Vernon Hills, Wildwood and Grandwood Park.

The Village maintains several backup emergency wells that undergo regular maintenance, flushing, and monthly bacteriological quality testing to ensure reliability if needed. Residents can review well sample results upon request. The water system includes storage facilities, pumping stations, and valve networks creating four distinct pressure zones throughout the community.

Water Treatment Process:
Water drawn from Lake Michigan undergoes treatment at CLCJAWA's Paul M. Neal Water Treatment facility in Lake Bluff. Their advanced purification method begins with ozone treatment to eliminate microorganisms and break down contaminants. The ozone, generated on-site from air, is bubbled into the water and later converted back to oxygen.

Next, a coagulant is added to remove sediment and impurities. After clarification, the water passes through activated carbon and sand filters to eliminate remaining turbidity. Turbidity (water clarity) is monitored continuously by automatic equipment and manually twice daily in the laboratory as a key indicator of water quality and filtration effectiveness.

Following filtration, ultraviolet light treatment inactivates any remaining organisms. Finally, the purified water receives chlorine for protection during distribution, fluoride for dental health, and a small amount of phosphate (a common food additive) to protect water from metals in home plumbing systems like lead and copper.

CLCJAWA has earned the Excellence in Water Treatment award for 13 consecutive years and was the third facility nationwide to achieve this distinction from the Partnership for Safe Water. This voluntary program, partially sponsored by the EPA, holds participants to higher standards than current water regulations require.
