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

JEFFERSON CITY---The Missouri Public Service Commission has approved a change in the infrastructure system replacement surcharge (ISRS) for St. Louis County customers of the Missouri-American Water Company (MAWC). MAWC filed an application with the Commission on August 26, 2019 seeking to change the ISRS. 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 April 1, 2019 through September 30, 2019. 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 approximately 4.7 cents per 100 gallons of water used. As a result of this case, the ISRS will be approximately 6.6 cents per 100 gallons of water used. The ISRS change is expected to take effect in December.
