Illinois American Water, a private utility company serving over 1.3 million customers in Illinois, has submitted a request with the Illinois Commerce Commission for a $134 million rate increase to help fund $577 million in water and wastewater system infrastructure improvements. This would mark the fourth rate hike by the company in the past 10 years, drawing criticism from consumer advocacy groups who call it a "money grab".

Why it matters

The proposed rate hike would significantly impact Illinois residents, especially in suburbs like Lisle where some homeowners already pay over $300 per month for water from the private utility. This highlights ongoing tensions between private water companies seeking infrastructure investments and consumer advocates arguing for more affordable and transparent pricing.

The details

Illinois American Water's rate increase request would result in an average increase of $14 per month for residential water customers and $28 per month for customers with sanitary wastewater systems. The company says the hike is necessary to fund $577 million in system upgrades, but consumer groups like the Citizens Utility Board have criticized the company's "rate hike machine" over the past decade. Proposed state legislation aims to reform how private water utilities are regulated, including capping water surcharge costs.

  • Illinois American Water submitted the rate increase request in February 2026.
  • If approved by the Illinois Commerce Commission, the new rates would take effect in January 2027.
