Water rates in McCall would increase about 6% in 2025 and 2026 under a proposal aired last week to the McCall City Council.The proposed rate increase would add about $4 per month to the average residential bill in each of the next two years, followed by about $3 per month each year thereafter.Overall, average monthly bills would increase from about $71 currently to about $88 in 2029, under the proposal, which the council is expected to consider adopting at a future meeting.The proposed 6% rate increase is 2% more than estimated in May when a $16.5 million bond issue was approved by McCall voters for water system improvements.The rate increases are needed to pay for debt payments tied to the bond issue, which the council pursued instead of seeking steeper rate increases that could have doubled monthly water bills to fund the system upgrades.The new rates would take effect Oct.
