SPRINGFIELD — Following almost a year of legal battles and fierce public opposition from many customers, water utility Aqua Illinois is set to raise its rates in 2025.
The privately owned water utility has not released an estimate of the exact impact the increase will have on customer bills in 14 northern Illinois counties. But the approved increase represents a 43% reduction from the utility’s original request, which would have raised bills by an estimated $30 per month, according to the Citizens Utility Board consumer advocacy group.
State regulators at the Illinois Commerce Commission approved the rate increase on Thursday — but not before the drastic reduction. In its initial requested rate hike from January, Aqua wanted to collect an additional $19.2 million from customers to pay for infrastructure upgrades, costs associated with taking over existing water systems and paying out a 10.8% return to investors.
But regulators cut the overall request, allowing the company to collect $11.6 million from customers while paying out a 9.6% return to investors.
The company argued throughout the case that the increase was necessary to recover costs from upgrading water systems to ensure safe water delivery.
“In the six years since our last rate increase, we made significant upgrades to water and wastewater facilities and infrastructure across Illinois,” Aqua said in a statement to Capitol News Illinois. “This rate decision highlights Aqua’s commitment to aggressively invest in infrastructure to improve service and reliability for our customers.”
ICC Commissioner Stacey Paradis said after the decision Thursday that the five-member panel “did not come to this decision lightly.”
“The commission regulates large water utilities and ensures they provide safe and adequate service,” Paradis said. “Transparent infrastructure investments and long-term planning are essential to ensure water and wastewater service meets regulatory requirements, environmental goals and customer needs.”
ICC commissioners also approved a new scheme for Aqua’s low-income customers. Starting in July, eligible customers with household incomes below 150% of the federal poverty level — about $48,000 for a family of four — will be able to receive a 70% discount on the portion of their bill that’s based on water usage.
Paradis noted that this move “is just a first step.” In explaining the ICC’s decision, ICC Chair Doug Scott said that, despite approving Aqua’s proposed formula for calculating rates, the commissioners worried that the company “may be unnecessarily shifting costs to residential ratepayers.”
To that end, the ICC is requiring Aqua to begin the process of creating a discount program for the entire bill with multiple tiers based on income. Those changes must be proposed by Jan. 1, 2027, or as part of Aqua’s next rate case, whichever is sooner.
This mirrors similar requirements recently placed on gas utilities by the ICC. Those discount programs, which went into effect last month, offer low-income households up to between 75% and 83% off their entire bill, depending on their income and which company they buy gas from.
“Illinoisans shouldn’t have to choose between groceries or running water when funds are tight,” Scott said in a Thursday statement. “Aqua’s new low-income discount rate will help keep water flowing for customers who are struggling to pay their utility bills.”
A similar bill discount program is expected to be announced for electric utilities in 2025, according to a statement from the ICC last month.
The ICC sent shockwaves last year when it unexpectedly sided with consumer advocates in several high-profile cases. Those included starting an investigation into a gas infrastructure program in Chicago and rejecting electric utilities’ plans for how to manage the grid as the state transitions away from relying on fossil fuels.
Consumer advocates had called on the state to cut the increase even more but reacted to the Aqua decision with cautious approval. The head of the Citizens Utility Board, which advocates for consumers in rate cases like this, said the Aqua decision is a “step in the right direction.”
“We believe that a 9.% profit rate for shareholders is still too high, but we are pleased that regulators rejected the company’s outrageous 10.8% proposal,” CUB Executive Director Sarah Moskowitz said in a statement.
Moskowitz also noted she and CUB were “encouraged” by the move to lower rates for low-income customers.
