, The main pipeline will extend from a storage tank approximately 12.7 miles to the North Fork of the Republican River. The pipe will be buried throughout its length. The pipeline will be supplied from the tank through a gated outlet, which will regulate flows. The main pipeline will flow by gravity from the tank to the river discharge structure. 4.6. Preliminary Design Key parameters and associated criteria for the preliminary design are provided in Table 3 below. Table 3: Key parameters and associated criteria for the preliminary design. Parameters Selected Design Criteria System Delivery Capacity Year 1 11,000 AF in 6 months Year 2 15,000 AF in 9 months Ultimate Perhaps up to 25,000 AF in 9 months Year 1 30.4 cfs Year 2 27.6 cfs Ultimate Perhaps up to 46.0 cfs Pipe Velocity Initial < 5 fps Ultimate < 10 fps Maximum Pipe Pressure 100 psi Well Capacity 1,000 to 2,000 gpm 4.7. Well Field Development Six to eight new high-capacity wells will be drilled at locations approved by the GWC. 4.8. Collector Pipelines A system of pipelines will be constructed to interconnect the wells and to convey water to the storage tank. A general layout of the pipelines is presented on Figure 2, which indicates that the pipelines will be 18 to 24 inches in diameter. 4.9. Conveyance Pipeline The main water conveyance pipeline will be a 36-inch diameter pipeline extending from a 1.0 MG storage tank approximately 12.7 miles to the North Fork of the Republican River following the general alignment shown on Figure 2. The tank will operate between a high water level at elevation 3690 and a low water level at elevation 3665. Releases from the tank will be regulated by a valve located near the tank, and an ultra- sonic flow meter will be provided approximately 30 feet downstream of the release valve. , r ' , r ' L� ' , 12
