A Letter to Hawthorn Woods, Kildeer and Lake County Customers

February 1, 2023


I’m pleased to share a quick update and progress on the commitments Aqua has made to ensure we are providing your community with excellent water service and enhanced customer communication. All of the system monitoring and emergency response actions communicated last year remain in place and will continue to be a part of our operational procedures going forward. To test their effectiveness, we will conduct tabletop emergency response exercises this Spring.

On the Infrastructure front, additional soil and pipe analysis is currently underway to obtain a better understanding of what caused last year’s main break. As you may recall, initial testing proved inconclusive while we suspect the main location in a marshy area was a contributing factor. We will continue to seek answers and provide any necessary solutions such as main replacement or relocation. An additional valve has been installed to quickly isolate any future breaks along that section of the main without interruption to the Spencer Loomis school or the Lake Zurich Middle School North.

Progress has also been made on the new water treatment facility with construction expected soon and still on target to be operational by November of this year. A contractor has been awarded and final IEPA permitting details are in review. This rendering depicts the new facility adjacent to the Aqua water tower off Schwerman Road in Hawthorn Woods.


In an effort to better communicate system disruptions, a new mapping tool has been added to our website so you can quickly observe the disruption location, description, required actions, and estimated time to resolve the issue. You will be receiving more information on how to effectively use the map as well as a notification when our new App featuring the disruption map, and more is released later this month. You may observe the live map here.

Finally, we held our third Water Service Advisory Council meeting on January 18 to discuss our progress as described above and details regarding Aqua Illinois’ rate case for 2024. Those details including the slide deck, minutes and materials can be found below in the Helpful Resources section, under Water Service Advisory Council.

We will continue to provide you with regular updates here on our website. We thank you for your continued partnership and we look forward to building trust through transparency and exceptional customer service.

Thank you,


David C. Carter

President, Aqua Illinois
