Rates Information

Water-service rates are based on the real costs of treating and delivering water to customers, and are regulated by the Indiana Utilities Regulatory Commission (IURC).

To determine rates, Indiana American Water and the Indiana Utilities Regulatory Commission staffs study costs of construction, maintenance, operation, administration and financing. Once the studies are complete, the company and IURC present any differing conclusions before an administrative law judge. Based on the judge’s opinion, the IURC sets the water rates.

Rates and billing frequency vary based on geographic area. Water customers are billed based on a regular meter reading, while wastewater customers generally pay a flat rate. 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 by an intricate, involved process. Water begins its journey from its source and travels through our highly sophisticated plants, into underground pipes, to its final destination, your tap. That source can be a river, aquifer, or an underground well.

Along the way, our teams of certified operators, scientists and engineers use the latest technology to oversee and monitor the water’s passage and progress. We test the water quality frequently, using leading methods we pioneered. We understand the value of clean, high-quality water on tap 24 hours a day, and are committed to delivering it reliably. Each year, we conduct thousands of tests and measurements using the most advanced technology and equipment available at our state-of-the-art, world-renowned research laboratory in Belleville, Illinois, and at our local utility labs.

Reliable high-quality water service improves our lives and communities by:
    • Protecting public health
    • Providing fire protection
    • Creating opportunities for economic growth.

At about a penny a gallon, water service is an excellent value. What other item in your household budget is as affordable? At Indiana American Water, we are committed to delivering outstanding service, that our customers depend upon, at an exceptional value.
