Rate Change Information


In November of 2017, Utility Services of Illinois, Inc. asked the Illinois Commerce Commission (ICC) for approximately $3.7 million of new additional revenue, which would be used to pay for $17 million of investments in infrastructure improvements throughout the State of Illinois.

A significant portion of these investments would improve water quality, increase water storage, lessen service disruptions due to main breaks and reduce inflow and infiltration to wastewater treatment plants.

Assuming the average residential customer uses 4,000 gallons of water a month, the original proposed rate increase would have increased that customer’s monthly bill to $67.79 and a residential sewer customer’s monthly bill to $56.05. Customers may use more or less water than the average and are only billed for the gallonage they use, at approved rates. While there is a fixed base charge billed monthly, there is no minimum gallonage charge.

On September 24, 2018 the ICC issued their order approving a rate increase, and the final rates approved by the ICC will be effective on October 4, 2018.

Assuming the average residential customer uses 4,000 gallons of water a month, the ICC’s final order will increase that water customer’s monthly bill to $65.01 and a residential sewer customer’s monthly bill to $54.47. Customers may use more or less water than the average and are only billed for the gallonage they use, at approved rates. While there is a fixed base charge billed monthly, there is no minimum gallonage charge.

Lower rates were made, in part, possible by the Tax Cut and Jobs Act of 2017 which reduced the federal corporate income tax rates from 35% to 21%, which was unknown at the time of the rate filing.
