Alternative Agricultural Water Transfer Methods -Grant Application Farm January 2(108 • Identify right-of-way corridors and significant property barriers • Recommend a preferred alignment 2. Refine Pump Station concepts • Further develop the pump station concepts -pumping head, pump size & no. of pumps per pump station, pump type • Refine pump station siting based on hydraulic considerations, environmental obstacles, electrical, etc. (ID a range or radius of site locations for each pump station) • Develop pump station layout concepts • Develop intake facility (1st pump station) concepts Deliverable: Recommended pipeline alignment, capacity, and configuration, preliminary cast estimate, and construction schedule for one or more pipelines that can deliver water from the Ft Lyon Canal and upstream on the Arkansas River to northeastern EI Paso County, i.e., to serve Pikes Peak Regional Water Authority. Task C - Delivered Water Quality it is likely that only raw water will be delivered to potential customers and that any treatment required will be their responsibility. The quality of the water delivered will likely have some influence on the price a customer would be willing to pay; therefore HDR will further examine the effects that a rotational fallowing program will have on the water quality of the Arkansas River and the basin as a whole. It is also expected that agricultural return flows will be decreased along the Arkansas River, thereby having an effect an the water quality (see Task D below). The analysis will focus on the fallowing constituents: • Nutrients • Metals • Temperature • E. Cali The areas that will be focused on will be: • Pueblo Reservoir • Just below Pueblo Reservoir • The Arkansas above the City of Pueblo • The Arkansas just below Fountain Creek and the City of Pueblo • One location further downstream to be determined at a later date The quality of water affects the treatability and has an effect on the value. The cast to treat raw water to potable quality will be examined far each of the above diversion paints. Deliverable: A Summary Report will be prepared covering Tasks and C, which includes pipeline alternatives and recommendations, storage alternatives the recommendations, and water zs
