Loan Feasibility Study for Raw Water Acquisition and Utilization Page 23 Each well will be equipped with 4 -in piping from the individual well heads to a common 8 -inch manifold pipeline. Operating pressures at this location will be approximately 245 pounds per square inch (psi). Each individual well will be metered with a 2 -inch meter with a meter interface unit (MIU) transmitting on a radio based frequency its meter reading to the central well house where each individual meter for each well can be read remotely. The small 20 -foot by 20 -foot well/control building will be located outside the 100 -year floodplain. A common master flow meter located in the well/control building will also be installed. All meters will be capable of being read remotely, from the District office or WTP, by Supervisory Control and Data Acquisition ( SCADA). Wells operations, allowing for the utilization of anywhere from four to seven wells to run collectively, will be controllable through the SCADA system and monitored from the District office. The wells' fl- inch manifold line will be connected to a single, 12 -inch raw water pipeline that will convey the raw water to an enlarged Brush Hollow Reservoir. This configuration allows the wells to be both metered separately and from a single master meter. The well control building, including parking lot, will require a parcel of approximately 1/4 acre in size. The proposed well field and well/control building are located on land owned and operated by the BLM. Use of BLM land for a well field and control building will require a permit from BLM. Water will be transported from the well field to an expanded Brush Hollow Reservoir through a 12 inch pipeline. The proposed pipeline route is shown on Figure 8. The proposed pipeline alignment will require bores under: the Lester and Attebery Ditch, Colorado State Highway 115, the Colorado Interstate Gas Company (CIG) high - pressure gas line, and US Highway 50. Necessary permits will be obtained for the bores. The total pipeline route is approximately 30,600 linear feet (5.8 miles). The majority of the pipeline will traverse private and publicly owned land. The necessary easement agreements will be obtained for access to private land. The necessary leases or permits will be obtained for access to publicly owned land including a limited amount of public right -of -way. Property owners along the proposed pipeline route have been identified, as shown on Figure 8. The pipeline will discharge into an enlarged Brush Hollow Reservoir. Brush Hollow Reservoir will be enlarged by construction of a four (4) foot raise to the existing Brush Hollow Dam. The raise will consist of placing fill material on the upstream slope of the existing dam, thus shifting the dam centerline slightly upstream. The downstream slope will be extended up four (4) feet vertically at the existing slope of 2H:1 V. A sufficient quantity of embankment foundation material is anticipated to be available in the reservoir area to construct the dam's raised section. Modification to the existing dam will require modification to the discharge pipe and spillway crest. Approximately 600 of of new storage will be developed through the proposed dam modifications. The District is currently in negotiations with BPW for the right to enlarge Brush Hollow Dam and utilize storage within the reservoir. 6.4 OPINION OF PROBABLE COST The opinion of probable cost of the selected project, Alternative 3, is presented in Table 5.
