There is no guarantee that Town water can continue to deliver water to Ute, however, allowance will be made in the pipeline for these flows at this time. Emergen!;)' Operations Ute Water has also indicated an interest in possibly utilizing the Cottonwood Creek pipeline to provide short term peak flows when normal sources of water are cut off. One reason for this need is that it may be necessary to shut down the Plateau Creek pipeline source during the reconstruction in 1998. Also, there is danger to both of its supplies during flood years; in case of a complete shutdown, an access to Palisade water for emergencies is a possible option. Although not all situations requiring peak flows are emergencies, the term 'Emergency Operation' will be used for simplicity to describe peak flow applications. Ute Water has mentioned two possible scenarios for peak flows: a maximum of 10 mgd from the Palisade water plant for short periods of time, and 4 mgd as supplemental water for longer periods. This would obviously require a much larger pipeline. Since Palisade must be able to provide this water on demand, but it is used infrequently, a special rate schedule would have to be established to help pay back extra costs for this. 4. Conclusions: Palisade/Ute Water N.-Is At the time of this report, discussions have been held with Ute Water on their near and long range water requirements. However, Ute Water had not made any definitive proposal to the Town of Palisade to confirm the need for peak flows, nor had there been any discussions on potential cost sharing. Since Pali~de i~ the sole loan applicant and is under a deadline to move forward with the prQject, the pipeline analysis will foclls on a pipeline for nonnal operation.~ only, i.e., to provide maximum day demands for the Town of Pali~de, plus flows which have historicallY been provided to Ute Water and any additional flows which the overall system is capahle of handling, This would not preclude Ute Water from contracting with the Town at a later date prior to design to request an expansion of the pipeline size. However, Ute Water would be solely responsible for that additional cost. 5. 'Carriage Water' to Ralance SllPP1y and Demand Another factor that should be considered in sizing the pipe is that when flow is controlled at the upstream end (the non-pressure pipe), it is difficult to exactly balance supply and demand. To compensate for this, it has been traditional for Palisade to release more water than needed and dump any excess water into Rapid Creek at a blow-off above the WTP. This water is used by downstream residents, which have junior water rights to Palisade's. This water is referred to herein as 'carriage water'. V-8
