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). The Missouri Public Service Commission sets rates.

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 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.

Missouri American Water received the final rate order by the Missouri Public Service Commission (PSC) on June 25, 2016. The case was filed on July 31, 2015.
• New water rates were effective on July 20, 2016.
• New sewer rates were effective on July 22, 2016.

Missouri American Water created a fact sheet for more information about the rate order and the change in you bill.

Missouri American Water's last general rate change was approved by the MoPSC in April 2012. The company's investments in water and sewer system improvements are the primary driver  behind this rate request.  From January 1, 2012 to January 31, 2016, Missouri American Water has invested approximately $436 million in water and sewer infrastructure statewide.  These improvements to local water and sewer plants, pumps and pipes are in service -- helping to enhance service quality, reliability, environmental performance, public health and fire protection for customers.
