Your Water Rates

Water-service rates are based on the real costs of treating and delivering water to customers, and are regulated by state public utilities commissions (PUCs). 

To determine rates, we work with PUC staffs to study costs of construction, maintenance, operation, administration and financing. Once the studies are complete, the company and PUC present any differing conclusions before an administrative law judge. Based on the judge’s opinion, the PUC sets the water rates.

Rates charged for service may vary based on a customer’s meter size. All customers pay the same rate for water usage. Customers are billed based on a regular meter reading, either monthly or quarterly for residential customers as well as for commercial and other public authority customers.

Rates can vary based on the cost of providing service in each of the communities we serve. Before it reaches your home or business, water is treated through an intricate treating and testing process to help ensure it meets or surpasses rigorous drinking water quality standards.

You can learn more about the rate setting process in our white paper: Challenges In The Water Industry: The Rate Approval Process.

Indiana American Water Rate Request - Cause No. 45142

Indiana American Water filed a petition with the Indiana Utility Regulatory Commission (IURC) on September 14, 2018 to adjust its rates for water service in the communities it serves across the state.

Indiana American Water’s ongoing infrastructure investments are the primary driver behind the request. The company is including $542 million of water infrastructure investments in its request. The investments are necessary to maintain and enhance service, water quality, system reliability, and fire protection capabilities for customers while keeping the cost of water service for most households their most affordable utility bill at about a penny per gallon.

The company last filed for new rates through a general rate filing in January 2014 and received an order from the IURC in January 2015.
