A bill for an act relating to sewer service by establishing a maximum rate increase charged by governmental entities.

This bill caps annual sewer rate increases for Iowa local governments (counties, sanitary districts, and sewer boards) at the lower of 102% of the previous year's total rates or the Midwest region's Consumer Price Index (CPI) increase. It excludes pre-July 1, 2025, debt repayment increases from this cap. If rates exceed the limit, the governing body must submit a voter referendum at the next general election; if rejected, customers receive refunds for overpaid amounts from the start of the budget year. The policy directly affects sewer service providers and ratepayers in communities operating municipal sewer systems.
