Missouri American Water, a subsidiary of American Water, has submitted an application to regulators requesting adjustments to its water supply and wastewater treatment service rates.

According to documents submitted to the U.S. Securities and Exchange Commission (SEC), the company's proposed new rate plan is scheduled to take effect on July 1, 2026. This rate adjustment application aims to reflect the company's funding needs in infrastructure investment, operating costs, and the continuous improvement of water quality and service reliability. As the main operating entity of American Water in Missouri, Missouri American Water's action is part of its regular regulatory review process to ensure that rates can cover the reasonable costs incurred in providing critical water services. The documents indicate that the application process will include public hearings and regulatory review. The final approval of the new rates and their specific structure will depend on the evaluation and decision of the State Public Service Commission.
