The Value of Water

Before it reaches your home or business, water is treated, stored and delivered through a complex process. Water begins its journey at the source -- rivers or wells -- and travels through sophisticated water treatment plants to its final destination, your tap. All along the way, our teams of certified operators, scientists and engineers use the latest technology to monitor the water's quality and progress. Reliable high-quality water service improves our lives and communities by:

  • Protecting public health
  • Providing fire protection
  • Creating opportunities for economic growth

Missouri American Water teams are dedicated to being responsible stewards of our communities' water systems. We invest in needed system improvements and manage operating and maintenance costs to help ensure quality, reliable water service now and in the future. At about a penny a gallon, water service is an exceptional value.

Missouri American Water’s Rate Request

Missouri American Water has filed an application with the Missouri Public Service Commission (MOPSC) to adjust rates for water and wastewater service in all of the company’s operating districts.
Missouri American Water’s ongoing investment in water and wastewater infrastructure improvements and the increasing costs of delivering high-quality, reliable service to customers are the main drivers behind the rate request.

The proposed rates reflect infrastructure investments of approximately $115 million statewide from May 1, 2010 to December 31, 2011 that are not reflected in the current water rates. These investments in water and wastewater plants, pumps and pipelines help to enhance service reliability for customers.

Additionally, many expenses associated with providing high-quality water service, such as fuel and power, have increased.
No rates will change until the MOPSC completes a comprehensive audit of the request. The process normally takes about 11 months and includes opportunities for public input.

The MOPSC is holding public hearings and requesting customer comments regarding the current rate case filing. The MOPSC has mailed a survey to Missouri American Water customers. The survey:

  • Provides information about upcoming public hearings and other methods of communicating to the PSC.
  • Gives customers an opportunity to comment on the quality of the service that we provide.
  • Provides information about Missouri American Water’s upcoming rate request. The cards outline the projected rate impact to the average residential customer’s bill, based on single tariff pricing and uniform statewide pricing.

How Water Rates are Set

Water service rates are based on the real costs of treating and delivering water to customers, and are regulated by the Missouri Public Service Commission (PSC). All Missouri American Water customers are charged rates approved by the PSC. You can learn more at the PSC web site:

 Public Service Commission

To determine rates, Missouri American Water and the PSC staff study the costs that the company has incurred for system improvements, maintenance, operation, administration and financing. Once the studies are complete, the company, the PSC and other interested parties present any differing conclusions before an administrative law judge. The public may attend public hearings or submit comments directly to the PSC staff.  The rate review process typically requires eleven months to complete and a final decision is made by the PSC.

Rates and billing frequency vary based on geographic area. In most areas, customers are billed based on a regular meter reading. Some wastewater service customers are billed based on a flat-rate billing. Missouri American Water rates are based on the true cost of providing water service to our customers. Rates vary based on the cost of providing service in each of the communities we serve.

Your Water Rates

On June 16, 2010, the Missouri PSC approved rate changes for Missouri American Water customers. The need for the change was driven largely by the approximately $96.6 million in water and wastewater system improvements made across the state from October 1, 2008 to April 30, 2010. These ongoing investments in improvements to local systems, plus increases in operating costs, are key drivers behind the rate changes.
