SECTIONFOUR <br />4.1 OVERVIEW <br />Formulation of Alternatives <br />The project configuration was developed prior to the development of this feasibility report. The <br />Company evaluated the potential for developing an internal exchange of water but decided not to <br />pursue this approach due to the lack of flexibility to delivery water to their shareholders. For the <br />purpose of this study, the No Action and the Pump Station alternative were evaluated. <br />4.2 NO ACTION <br />If the pump station system is not constructed the Company will not meet the present and future <br />needs of the shareholders. The delivery of the water from the reservoir will become more <br />complicated due to the present exchange arrangement. Development is projected to continue in <br />the area below the reservoir which will even reduce the exchange at the Boulder headgate even <br />more in the future. URS believed that the No Action alternative was not a viable alternative and <br />it was precluded from further consideration. <br />4.3 PUMP STATION <br />The project will supply irrigation water to the North Branch Ditch and the Upper Lateral Ditch <br />located upstream of Panama Reservoir. The project consists of three main components which <br />includes a pump station with reservoir intake pipe, and two separate pipelines to supply the <br />irrigation ditches. <br />A pump station and reservoir water intake system will be located along the northern reservoir <br />rim. When the reservoir is at high water level, the pump station will be surrounded by water and <br />will be essentially an island with the exception for an access road connecting the shoreline with <br />the pump station area. The following describes the general pump station configuration: <br />1. The pump station supply system consists of a concrete intake structure with three intake <br />screens and a 300-foot-long 36-inch reinforced concrete pipe (RCP) from the intake <br />structure to the pump station wet well. <br />2. The pump station will be located on an access island surrounding the pump room <br />building constructed of compacted earth fill. An earth fill embankment type access <br />roadway will be extended from the reservoir access road to the pump station. <br />~.S 4-1 <br />
