<br />o Capital and Operational Costs: <br /> <br />Costs for the groundwater management projects summarized above include up-front <br />infrastructure costs, consisting primarily of wells, pumps, and collection/distribution <br />systems, and annual operations and maintenance costs. Potential costs associated with <br />third party impacts have not been evaluated. The costs presented below may be higher if <br />there are third party impact costs. <br /> <br />Several of the groundwater management: options are the subject of the HDR report, <br />Depletion Mitigation Study Phase I, which was recently made available to Boyle. Cost <br />information provided in the HDR report was used to supplement this cost analysis. Costs <br />for these projects are outlined below. <br /> <br />Option 1: Active Pumping from High Groundwater Areas. The cost to install a shallow <br />well and pump capable of pumping up to 1000 gpm was estimated to be $15,000 based <br />on recent cost estimates obtained from T)3NRD in connection with the Plum Creek <br />demonstration project. This cost may be! higher depending on site specific conditions and <br />the depth of the well. Assuming nine w~lls are required to pump a total of 3,000 ac-ftlyr, <br />the total cost for wells and pumps is estimated to be $135,000. The cost of the collection <br />system could vary significantly depending on where this type of project is applied and the <br />length of pipeline required to convey water back to a tributary, such as Lost Creek, or the <br />Platte River. It was assumed that the project would be implemented under the Phelps <br />Canal system and only one collection system would be required to deliver water to either <br />Lost Creek or North Dry Creek. The cost of the collection system was estimated to be <br />$1.2 million. The costs to improve the c~toffs are included under the Dry CreeklFt. <br />Kearny Cutoff projects. The total capital cost of this project is estimated to be about $1.3 <br />million. Annual operations and maintenance costs were estimated to be $30,000. <br /> <br />Option 2: Passive Lowering of the Groundwater Table. It was assumed that the cost to <br />induce farmers to dry land farm is comparable to the estimated cost to lease water. On an <br />annual basis, the cost of a leasing progrm;n was estimated to range from about $80 to <br />$190 per acre-foot of consumptive use s~ved. It was assumed that the upper range of <br />these costs includes CNPPID's revenue lbsses of $24.49 per contract acre associated with <br />reduced deliveries. The total cost could tange from about $240,000 to $570,000 based on <br />a reduction in consumptive use, of 3,000 ac-ftlyr. <br /> <br />Option 3: Groundwater Irrigation. The cost associated with this project consists <br />primarily of well construction and pump :costs. Assuming nine wells are required to pump <br />up to 3,000 ac-ftlyr, the total cost for wells and pumps is estimated to be $135,000. This <br />does not include annual operations and maintenance costs and other associated costs to <br />improve irrigation equipment if necessary. The conversion from surface water irrigation <br />to groundwater irrigation may require irrigation system improvements such as the <br />installation of center pivots. <br /> <br />Option 4: Conjunctive use. The costs associated with this project consist primarily of <br />well construction and pump costs and the cost of a recharge collection/distribution <br />system. Assuming nine wells are required to pump up to 3,000 ac-ftlyr, the total cost for <br />wells and pumps is estimated to be $135;000. Depending on the configuration of the <br />recharge system needed for a conjunctiv~ use project, additional costs would be incurred <br /> <br />C:\Drnft Waler Action Plan (May 30. 2000)\wllpC report (Version 6 BND2)-.doe 40 <br />
