<br />Including 'carriage water' and Ute supplemental water in the analysis may not <br />necessarily require any oversizing of pipes. The exact theoretical pipe diameter <br />for carrying the Town's flows is first calculated. Since pipes are available <br />only in specific sizes, the next leu-ger pipe is always selected and this <br />automatically provides extra caPacity. <br /> <br />6. Combined Water Demand. <br /> <br />Pipeline Alternatives: The four scenarios for pipeline capacity which were <br />discussed are as follows: <br /> <br />Normal Operation <br /> <br />Scenario A <br />Palisade <br />Only <br /> <br />Scenario B <br />Palisade <br />& Ute <br /> <br />Palisade Max.

The low elevation equalizing reservoir (Alternate 3) <br />must have adequate size to carry water through the summer, when outflow is <br />expected to be greater than inflow. It is refilled during the winter, when <br />demand drops off. <br /> <br />C. <br /> <br />ALTERNATIVE 1 - NEW PIPELll-ffi DESIGNED FOR NON-PRESSURIZED <br />FLOW <br /> <br />1. Factors to Consider in Analysis of a Non-Pressurized Pipelinp.. <br /> <br />Description of Pipe. The existing Cottonwood Creek pipeline from Cabin <br />Reservoir to the water treatment plant consists of the following segments. <br />Each operates differently from other segments under non-pressurized flows and <br />has its own capacity. <br /> <br />V-9 <br /> <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />I <br />
