Central Lake County

Joint Action Water Agency

Meeting the highest standards for quality in the production and distribution of drinking water to Central Lake County since 1992

In 2005, the Agency received the Phase IV Excellence in Water Treatment certification from the Partnership for Safe Water, identifying its staff and facilities as meeting the highest standards for quality in the production and distribution of drinking water. CLCJAWA is the third organization to be granted this prestigious recognition and the first conventional water treatment plant in the United States to achieve this distinction.

Grayslake Data Center Water Usage Information

A Data Center Campus is under development in the Cornerstone business park at Person and Allegheny Roads in Grayslake. The Village of Grayslake supplies water to the business park that they purchase from the Central Lake County Joint Action Water Agency (CLCJAWA).

T5 Data Centers’ design team has indicated to us that the total campus water use will be less than 50 thousand gallons per day. CLCJAWA pumps approximately 20 million gallons per day to 20 communities. Once complete, the data campus will increase CLCJAWA’s daily pumpage by 0.25% having negligible impact on our system. This information was presented to the Illinois Commerce Commission on January 15, 2026. The presentation slides and script may be found here.
