 88. PROJECT:Riverton Water Supply
SPONSOR:City of Riverton
LOCATION:Fremont County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date
Level III 59 1996 I $220,000* 1999
*67% grant, balance of project cost from other sources.

The city has recently extended its water mains to the Wyoming State Honor Farm. An additional well has been added to their supply system in this area to aid in equalization of pressures, and to help supply the additional growth they foresee in this area.

Phase I of the project has been completed. Phase II, installation of the pump, pipeline and appurtenances, are scheduled to proceed during 1999. However, a funding shortfall has occurred. Additional funding is needed due to the following:

  • First, at the time of the original estimates, pipeline construction costs were lower and the pipeline was increased from 8" to 12". Furthermore, the pipeline was relocated from the north side of Honor Farm Road to the south side. This change requires the installation of some large diameter storm sewer pipe.

  • Second, additional well testing was required to isolate some poor quality water. This resulted in a substantial increase to the engineer's fees.

  • Third, the poor quality water is believed to be originating from the bottom portion of the well. This section will be plugged at a cost of $14,310.

  • Fourth, the cost of the well house, well pump, pipeline and appurtenances will cost more than originally projected.

  • Finally, because of the size of the well pump, a motor controller with soft-start and soft-stop will be added.

The WWDC recommends that the project budget be increased by $92,000 with a 67% grant. The balance of the project costs shall be paid from other sources.
