evaluated based on land and power availability. The locations selected for the pumping <br /> stations are as described below. <br /> Pumping Station No. 1 (PS-1)will deliver water from the PS-1 forebay to Pumping <br /> Station 2 forebay.It will be located near the South Platte River on land just north of <br /> Highway 7 between the Brighton and Brantner ditches in Adams County,Colorado. <br /> It will consist of a forebay,suction header,suction piping,pumps,discharge piping, <br /> discharge header,surge tank and electric transformer. <br /> Pumping Station No. 2(PS-2)will lift water from the PS-2 forebay to Pumping <br /> Station forebay. It will be located about 1,500 feet southwest of the intersection of E- <br /> 470 and 96th Avenue in Adams County, Colorado. It will have the same <br /> appurtenances as PS-1,except with a smaller forebay. <br /> Pumping Station No.3(PS-3)will lift water from the PS-3 forebay to the new <br /> ARWPF. It will be located on 20 acres of land just south of I-70 and east of Powhaton <br /> Road in Arapahoe County,Colorado.A 75-by-678-foot access and utility easement <br /> extends from the property east to Powhaton Road. It will have the same <br /> appurtenances as PS-2. <br /> Conveyance System Components <br /> The project sponsor,Aurora Water,and its team of professionals,began preliminary design <br /> activities for the PWP in 2004.Development of preliminary design packages led to clearer <br /> definition of PWP facilities.With respect to the Conveyance System,five design and bid <br /> packages were originally identified in 2004 for implementation as part of the PWP.Through <br /> value engineering,Package B(Special Crossings and Micro-Tunneling)was eliminated as a <br /> separate bid package, and the special crossings were incorporated into the respective <br /> pipeline segments where required. Thus,the Conveyance System for the Prairie Waters <br /> Project is now comprised of the following four bid packages. <br /> Package E-Pumping Stations No.1,2,and 3 <br /> Package G-Transmission Pipeline Segment No. 1 <br /> Package H-Transmission Pipeline Segment No. 2 <br /> Package I-Transmission Pipeline Segment No.3 <br /> The project sponsor, Aurora Water,seeks funding in the form of a loan from the Colorado <br /> Water Conservation Board Construction Fund Water Project Loan Program for use on these <br /> conveyance elements of the PWP. The following sections of this document describe Bid <br /> Packages E,G,H,and I,the water conveyance elements of the PWP. <br /> Conveyance Pipeline <br /> The 33-mile,raw-water pipeline will consist of a 60-inch-diameter flexible steel pipe that <br /> will convey raw water from the Pumping Station No.1 forebay to the new Aurora Reservoir <br /> Water Purification Facility (ARWPF/South Campus)in three segments.The pipe will be <br /> buried for its entire length,and will include trenchless crossings beneath waterways, <br /> wetlands,highways,major arterial streets,railroads and canals as required. The conceptual <br /> layout for the pipeline is divided into three segments as shown in Figure 2 above. <br /> 8 <br />
