Storm Lake residents could see some of the biggest utility rate increases in years, as the city moves toward major upgrades to its sewer system and a new water treatment plant.
The Storm Lake City Council has set two public hearings for early May on proposed increases to both sewer and water service rates — changes city officials say are necessary to keep major infrastructure projects on track.
On Monday night, the council voted to schedule a May 4 hearing on an ordinance that would raise sewer rates beginning July 1.
City Finance Manager Tyler Gibbins told the council the increase — about $4 to $5 a month for the average household — is aimed at preventing larger jumps later as the city prepares for state‑mandated nutrient reduction requirements and ongoing upgrades to the wastewater system.
The additional revenue — about $474,000 a year — would help cover the city’s share of future grant‑funded projects and ensure the utility can keep up with maintenance and repairs. If approved, residents would see the new rate reflected on bills due August 15.
The council also set a May 4 hearing on a separate ordinance to increase water service rates. That proposal stems from months of work by the Water Treatment Plant Ad Hoc Committee, which studied Storm Lake’s long‑term water needs and recommended gradual increases to help finance a new water plant, additional wells, and expanded storage.
Gibbins said the committee’s findings were clear: the 1978 water plant is operating near capacity year‑round, and delaying action would only raise costs.
Under the proposal, the average residential user would see an increase of $12 to $15 per month beginning July 1.
Both hearings will be held at 5 p.m. Monday, May 4, in the Storm Lake City Council Chambers at city hall. The council will take public comment before considering the first readings of both ordinances.
