American Water Works Company’s Missouri subsidiary has filed for a significant rate increase to support major infrastructure spending. Missouri American Water is requesting annualized incremental revenue of about $179 million, excluding infrastructure surcharges of approximately $32 million, of which $18 million remains subject to approval.
The request is based on a 10.50% return on equity and a capital structure of 50.3% equity and 49.7% long-term debt. It is driven primarily by roughly $1.6 billion of water and wastewater investments planned and completed from June 2025 through May 2028, the forecasted future test period. Missouri American Water anticipates new rates could take effect in June 2027, following an MoPSC review that can take up to 11 months and includes public input.
If approved as filed, the average residential water bill in St. Louis County using 5,900 gallons per month would rise by about $23 per month, while customers outside St. Louis County using 4,500 gallons per month would see an increase of about $15 per month. The amended report itself only corrects the XBRL cover page’s document period end date and does not change the underlying rate request disclosure.
