 72. PROJECT:Natrona County Regional Rehabilitation
SPONSOR:Natrona County Regional Water System Joint Powers Board
LOCATION:Natrona County
Purpose Chapter Session Account Appropriation Due Date
Level III-I 206 1995 II $1,500,000* 1999
Level III-II 59 1996 II $5,300,000* 1999
*50% grant, 50% loan (4%, 30 years)

The aggregate population of the entities served by the Natrona County Regional Water System Joint Powers Board is approximately 60,000 residents. The Level II feasibility study of the Natrona County Regional Water Supply Project identified $60,000,000 of needed improvements, of which $37,000,000 would be eligible for WWDC assistance, and identified a phased approach for completing the project. Some infrastructure improvements should be completed by 1997 to facilitate operation of the regional system.

The Level II feasibility study of the Natrona County Regional Water Supply Project recommended that the Fort Caspar and Dempsey Acres Well Fields be rehabilitated. The estimated cost for this component of the project is $4,814,000. The project will be completed in three phases: drilling, final design, and construction. The well fields are a primary water supply for the regional system. The existing wells are old and production has dropped. The project would serve to increase the well production to its permitted amount. In addition, several water storage tanks will be operated by the Joint Powers Board. Telemetry modifications to the tanks and some rehabilitation is required to extend their usable life. The estimated cost for the improvements to the storage tanks is $586,000. The funding for these project components would be provided from the Rehabilitation account. Because of limited funds available, the WWDC recommended that this project be phased.

The first phase of the well rehabilitation project has been constructed. The second phase is under construction and will be completed in the next two years. The rehabilitation of the storage tanks is currently under design. One of the tanks has been identified as needing a new inlet pipe to help prevent stagnation of the water in the tank. Funding for this was not identified in the Level II study and it is now being requested by the joint powers board.

The WWDC recommends that the project budget be increased by $57,000 with 50% being a grant and 50% being a loan with an interest rate of 4% for a term of 30 years. It is further recommended that the project due date be extended to 2004.
