BELLEVILLE, Ill.--(BUSINESS WIRE)--On Dec. 15, 2022, the Illinois Commerce Commission (ICC) issued an order adjusting base rates for Illinois American Water, effective Jan. 1, 2023. The rate change request, which was filed in Feb. 2022, was driven primarily by over $1.1 billion in completed or planned investment, reflecting approximately $948 million in water system improvements and $204 million in wastewater system improvements in Illinois from 2018 through 2023.

The rate order will result in a total annualized revenue increase of approximately $67 million. The additional revenues will support continued investment in critical water and wastewater infrastructure throughout the state, including the replacement, lining and installation of approximately 141 miles of aging water and wastewater pipelines. Investments would also include, among others, upgrading water and wastewater treatment plants, storage tanks, wells, pumping stations, fire hydrants, meters and manholes across the state.

“By making prudent, ongoing investments to maintain and upgrade our water and wastewater systems, Illinois American Water is committed to the safety and reliability of our systems in the communities we serve,” said Rebecca Losli, Illinois American Water president.
