Grantsville authorized up to $50 million in sewer bonds for a new treatment plant
In February the council set a $50 million ceiling for sewer revenue bonds to build a new wastewater treatment plant. An April rate study assumed about $25.2 million in private bonds and a $16 million state loan, and the council adopted new sewer rates the same night. The records reviewed do not show what has actually been borrowed.
Continuing story: Auditing Grantsville
Grantsville's City Council voted 5–0 on Feb. 4, 2026 to approve Resolution 2026-02, which allows the city to issue up to $50 million in sewer revenue bonds with a term of up to 34 years and a maximum interest rate of 6%. [1]
Alex Buxton of Zions Public Finance told the council that approval "did not obligate the City to issue bonds" but set parameters that let staff proceed, according to the minutes. He called the 6% rate a conservative ceiling. [1]
The council approved the Feb. 4 minutes on Feb. 18, 4–0, with Councilmember Rhett Butler absent. [4]
Why the city says it needs a plant
At the Feb. 18 meeting, Public Works Director Christy Montierth and the city's engineering consultant said the city fell out of compliance with phosphorus limits in 2019 and later with ammonia limits, and that its lagoons date to 1972. They said the city must comply by March 31, 2029, according to the minutes. [4]
They said the plant's estimated cost had risen from about $32 million in 2022 to about $48 million. No action was taken that night. [4]
The financing plan
The final-draft sewer rate study in the council's April 1 packet assumed $25,152,175.15 in private bond proceeds over 30 years at 5.052% interest, a $16 million Utah Water Quality Board loan over 30 years at 0.75%, and a $1 million engineering loan at 0% over 20 years. [3]
The study says it "should be updated" once the actual terms of the private bond are confirmed. [3]
At the April 1 meeting, Mayor Heidi Hammond said the city had secured about $16 million at a lower interest rate, and City Manager Michael Resare said the city had accumulated about $4 million to $5 million from prior rate increases for the project, according to the minutes. [2]
New sewer rates
The council approved Ordinance 2026-12 on April 1, 4–0, with Councilmember Brittany Skinner absent. The minutes say it lowered the base rate and added a usage charge based on each household's winter water use, with the new rates taking effect in July. [2]
The motion directed staff to research the feasibility of an assistance program for elderly and low-income residents, which Councilmember Derek Dalton proposed. [2]
The $50 million figure is a borrowing ceiling. The rate-study amounts are planning assumptions. Neither is a record of money borrowed or spent.
