� <br />Deliverable: Forty-year Financial Plan for the operation of the Super Ditch Company, <br />including the spreadsheet model and its supporting documentation. <br />AA of the deliverables for TASK E will be included in an Economics Technical Memorandum. <br />Task F— Pipeline Alternatives (Alternative Permanent Ag Transfer Method Grant Program) <br />HDR's Final Feasibility Study involved an assessment of the exchange capacity remaining <br />in the Arkansas River between Pueblo Reservoir (upstream) and the John Martin Reservoir. This <br />quantity was estimated as the minimum flow rate remaining after meeting all existing demand <br />requirements, including minimum instream flows and downstream commitments. While it appears <br />that there may be some capacity to exchange Super Ditch water upstream to Pueblo Reservoir, in <br />reality, much of that capacity may be consumed by exchanges already adjudicated or pending in <br />water court, e.g., Colorado Springs et al's Colorado Canal decreed exchange, and the Aurora- <br />Highline Canal pending exchange. <br />The recent Boyle pipeline study looked at combining the alignments of four contemplated <br />pipeline projects. Because the Arkansas River exchange capacity is quite limited, it will be <br />necessary to find other means to transport water to the Project's customers. One such option is <br />the construction of new transmission pipeline(s). This Task will build on the information in the <br />Boyle study and identify the following with regard to water leases by the Super Ditch Company: <br />• Required pipeline capacities <br />• Number of pipelines to be constructed (i.e., would there be multiple pipelines taking water <br />from various points along the Arkansas River, or would there be one major pipeline, <br />with branches serving various customers) <br />• Location and timing of diversions to pumping facilities <br />• Pump station locations and capacity requirements (e.g., number of pumps, pump power <br />requirements, etc.) <br />• Pipeline delivery locations <br />• Cost estimate, including materials, construction, O&M, right-of-way/easement acquisition, <br />etc. <br />All pipeline configurations developed during this phase of analysis would be preliminary and <br />subject to revision during final design. However, a level of detail would be achieved that is <br />sufficient to meet any requirements for a water court application or local land use permit, as <br />described below: <br />1. Refine the Pipeline Alignment for the preferred altemative (Timber Lakes) <br />• Identify more hydraulically efficient alignment(s) <br />• Research and identifjr environmental concems and obstacles <br />• Evaluate costs and availability of electrical power <br />• Identify right-of-way corridors and sign�cant property barriers <br />• Recommend a preferred alignment <br />2. Refine Pu►�p Station concepts <br />• Further develop the pump station concepts — pumping head, pump size & no. of <br />pumps per pump station, pump type <br />January 22, 2009 7 <br />
