JEFFERSON CITY---Missouri-American Water Company (MAWC) has filed applications with the Missouri Public Service Commission seeking to change the Water and Sewer Infrastructure Rate Adjustment (WSIRA) that appears on the bills of MAWC water and sewer customers.
State statutes provide eligible water and sewer corporations with the ability to recover certain eligible infrastructure system replacement costs without the need to file a formal rate case with the Public Service Commission. These investments in infrastructure are recovered through a WSIRA. MAWC seeks a change in the WSIRA to provide for the recovery of costs for infrastructure system projects eligible for WSIRA recognition. These costs are not currently reflected in customer bills.
Residential St. Louis County water customers of MAWC currently pay a monthly WSIRA of approximately $0.94 per 1,000 gallons. MAWC seeks to adjust the monthly WSIRA to approximately $1.30 per 1,000 gallons of water. MAWC residential water customers outside of St. Louis County currently pay a monthly WSIRA of approximately $0.47 per 1,000 gallons. MAWC seeks to adjust the monthly WSIRA to approximately $0.62 per 1,000 gallons of water.
Arnold residential sewer customers of MAWC currently pay a monthly WSIRA that is 0.8991% of the total monthly sewer bill. MAWC seeks a monthly WSIRA that is approximately 1.0559% of the total monthly sewer bill. For all other MAWC residential sewer customers, the current monthly WSIRA is 5.5519% of the total monthly sewer bill. MAWC seeks a monthly WSIRA that is approximately 6.5297% of the total monthly sewer bill.
