(Riverton, Wyo.) – The next phase of a $9.2 million water supply project began this week when Jerry Bornhoft Construction began work on a pump station at the new two-million gallon water tank on Griffey Hill. The pump station will supply water uphill from the new reservoir to the site of the Wind River Job Corps Center, which is now under construction. It will also serve to reverse the flow of water from the tank when other areas in the city need maintenance.
“The contract to build the tank was separate because tank builders usually only build tanks, and not the related infrastructure,” said Dawn Willhelm, the city’s Utility Division Manager from her office this morning. DN Tanks was awarded the $2.6 million contract for the new water reservoir, and they completed work there earlier this month. The site was then graded to slope.
Willhelm said the Pumping Facilities project includes two booster stations, one at the Water Treatment Plant next to Central Wyoming College to boost the water to the new tank through the completed 24-inch transmission line, and one at the new tank (currently the large hole on site) to boost the water up Airport Hill, and the well house station for Well # 17 near the new tank. The project came in at $3,307,232.00 with four contractors bidding. The Engineers Opinion of Probable Cost was $4,060,000.00.
Eventually, the plan is to extend a city water line to the west to tie into a city water line that currently extends along Riverview Road.
The Wyoming Water Development Commission is providing 66 percent of the total cost of the water supply project, the city is responsible for the other 33 percent.
