About the Aqua Illinois Rate Filing
On May 26, 2026, Aqua Illinois filed an application to adjust water and wastewater rates to reflect nearly $171 million in capital infrastructure projects we have made or plan to make from 2025 through the end of 2027. Our comprehensive request allows us to continue our infrastructure work that improves reliability and water quality, enhances customer service, and helps to support our commitment to the communities we serve. The request also supports our response to new regulations that require replacement of lead service lines, while also defending against cyber-security threats.
Examples of some of the infrastructure investments we have made across the state include:
- Water Distribution System projects like storage tank renovations, water mains, meter and valve replacements.
- Installation of new water quality filtration systems and renovation of existing systems for both primary and secondary water quality concerns.
- Water and Wastewater Treatment Plant and collection system improvement projects.
- Installation of remote monitoring in water and wastewater systems.
- Lead service line identification and replacement.
Aqua Illinois requested rate increase requires investigation and approval by the Illinois Commerce Commission (ICC). The rate review process can take up to eleven months, which means customers can expect any approved increases to take effect at the end of May 2027.
