 53. PROJECT:Moorcroft Water Supply
SPONSOR:Town of Moorcroft
LOCATION:Crook County
PROGRAM:New Development
Purpose Chapter Session Account Appropriation Due Date
Level III 28 1994 I $930,000* 1997
*67% grant, 33% loan (4%, 30 years)

The Town of Moorcroft has a population of 768. The town's primary water supply is several groundwater wells. The water table is dropping and affecting the yield of the well field. A supplemental supply, which is utilized extensively, involves the purchase of water from the Gillette Madison Pipeline. In 1990, the town requested WWDC assistance in evaluating its water supply options.

The Level I study examined the town's existing water system, including their wells, storage facilities, and delivery system. The study identified several alternatives for increasing the reliability of the town's supply. In 1992, additional work was performed to analyze the alternatives and to select the most effective water supply option for the community. Results of these studies indicated that the town needed additional storage, and could be supplied by a new Lance or Fox Hills formation well. With typical WWDC funding, purchase and maintenance of a new well would be less expensive for the town than continuing to purchase water from the Gillette Madison pipeline. In 1993 the town requested Level II funding for a test well, and Level III funding for a new storage tank, transmission, and collection pipelines. Since the configuration of the system could be affected by well yield, WWDC recommended the Level II study be conducted before the other funding was considered.

The test well constructed in 1993 was not as productive as desired, but will provide an adequate supply in conjunction with the town's existing wells, until the town experiences substantial growth. The town has agreed to relinquish their right to the Madison pipeline, except in times of emergency, thereby allowing the capacity in the pipeline reserved for Moorcroft to be used to solve water supply problems in the Gillette area. Conceptual designs and cost estimates have been prepared for the Moorcroft Water Supply Project. The total estimated project cost is $930,000, which will provide a pump station, a storage facility, and pipeline improvements.

In 1994, the project was advanced in the New Development Program to Level III status. The sponsor has executed legal agreements with the WWDC and the project design is underway. Construction will commence in 1996.

No legislative action is required on this project.
