Infrastructure System Replacement Surcharge (ISRS) Request

Missouri-American first established an ISRS on customer bills in December 2003.

Missouri-American seeks the ISRS change to reflect infrastructure replacement investments made by the water company since February 2016. The costs in this ISRS request are not currently in rates.

Applications to intervene and participate in this case must be filed no later than May 31, 2017, with the Secretary of the Missouri Public Service Commission, P.O. Box 360, Jefferson City, Missouri 65102 or by using the Commission’s Electronic Filing and Information System (EFIS) at

As a result of a rate case decision made on May 26, 2016, the ISRS for residential customers was re-set to zero. In its application, Missouri-American Water Company seeks to adjust the ISRS that residential customers pay to approximately $0.02 per 100 gallons of water used.

The infrastructure system replacements for which Missouri-American seeks ISRS recognition are either: 1) mains and associated valves and hydrants installed as replacements for existing facilities that have worn out or were in a deteriorated condition; or 2) a main cleaning and/or relining project; or 3) infrastructure facility relocations due to construction or improvements of a highway, road, street, public way or other public work required by or on behalf of the United States, the State of Missouri, a political subdivision of the State of Missouri, or another entity having the power of eminent domain.
