Infrastructure Surcharge to Change for St. Louis County
Customers of Missouri-American Water Company

JEFFERSON CITY---The Missouri Public Service Commission has approved a request filed by the Missouri-American Water Company (MAWC) to change the infrastructure system replacement surcharge (ISRS) on the bills of its St. Louis County customers. MAWC first established an ISRS on customer bills in St. Louis County in December 2003.

The ISRS adjustment reflects infrastructure replacement investments made by the company during the period January 1, 2021 through July 31, 2021. These costs are not currently included in MAWC’s rates.

Residential customers in the company’s St. Louis County service area currently pay an ISRS of $0.00 per 1,000 gallons of water used. As a result of this case, the ISRS will be approximately $0.235 per 1,000 gallons of water used. The ISRS change is expected to take effect in October.
