Construction of Rifle’s new water treatment plant and system upgrades to kick off next spring

From the Glenwood Springs Post Independent (Mike McKibbin):

The 16- to 24-month project will include improvements to the city’s raw water pump station, a new 24-inch raw water pipeline to the new 40,000-square-foot plant, a radio tower at the Graham Mesa plant for remote data transmission of the city’s water system to the pump station and then by cable to the new plant, and connections to water transmission and main lines.

The original plan was to start work this summer, but Utilities Director Dick Deussen said it took much longer than anticipated for the Colorado Department of Public Health and Environment to sign off on the final permits. That led the city’s consultant, Malcolm Pirnie ARCADIS, to reassign staff engineers to other projects, since they could not proceed without the permits, Deussen said.

The city also changed the location of the plant within the site east of Rifle, off U.S. Highway 6, so additional groundwater and other tests were required by the health department and U.S. Army Corps of Engineers, added Resident Engineer Jim Miller.

“It’s closer to the wetlands, so we need to know how to manage that,” he said. “We also need to know about the bedrock elevation.”[…]

In their regular meeting after the workshop, City Council approved a resolution supporting an application for a Colorado Department of Local Affairs Energy and Mineral Impact Assistance Fund grant to help acquire and install a natural gas-fueled backup generator at the plant. The 1,600- to 1,750-kilowatt generator, with emissions control equipment, would serve as a secondary power source to keep the facility operating during power outages, city Government Affairs Coordinator Kimberly Bullen told council. It would also allow the city to take advantage of Xcel Energy’s interruptible service option credit, Miller noted. That credit allows Xcel to call the city and ask them to reduce electrical usage at the plant due to heavy summer demands on their distribution system, Miller explained…

The estimated cost of the generator is more than $1.4 million, with the city seeking half that amount, or $735,000, in the grant application. The city’s 50 percent share would come from the Colorado Water and Power Resources Authority loan that’s funding the project, Bullen said.
