Bids for Rifle's new $25.5 million water treatment plant are scheduled to be sought in December, with construction beginning in March and lasting two years.
That's according to an update posted on the city of Rifle's website on Aug. 23.
In the coming months, the city will finalize the design for the new plant, followed by bids in December, according to the update. After bids are received and evaluated, a bid award will be made.
The Colorado Department of Public Health and Environment will review the final plans for the plant and specifications for review and approval in October.
The final cost of the new plant may vary, depending upon the final design and number of bids received. Nine contractors have been prequalified to bid on the work.
The city will borrow approximately $25.5 million from the Colorado Water and Power Development Authority to build the plant. The loan comes from a special fund dedicated to water projects. The effective interest rate will be 1.86 percent, with $2 million loaned interest-free, resulting in what the city called "an overall historic low loan rate."
Repayment of the loan will require an increase in city water rates, beginning in September, which could cause doubling of some customers' water bills.
However, the City Council has voted to place a measure on the November general election ballot to increase the city sales tax by 3/4 cent to help finance the plant. If approved by voters, the sales tax would "significantly" reduce the water rate increase, according to the update.
