<br /> <br />e <br /> <br />e <br /> <br /> <br />-URS <br /> <br />~~R~~S"_, <br /> <br />Client: <br /> <br />Denver Water <br /> <br />Location: Colorado <br />Services: Sediment Dredging and Transport <br /> <br />Project Background <br /> <br />URS conducted studies for estimating the long-term sediment delivery into <br />the Strontia Springs Reservoir and analyzing the least-cost methods for <br />trapping and removing the sediments entering the reservoir. The Strontia <br />Springs Reservoir serves as the intake for the Denver and Aurora water <br />supplies from the South Platte River and is a vital link in supplying water to <br />the Denver Metro area. Forest fires devastated the upstream watershed, <br />which in turn, increased the sediment supply into the reservoir. Denver <br />Water was faced with protecting their water supplies from excessive <br />depletion of storage. URS analyzed several methods for trapping and <br />removing the sediment from the watershed. The least-cost option involved <br />purchasing a dredge and designing a 7 -mile long HDPE pipeline to carry the <br />slurry from the reservoir to areas where the slurry could be deposited. It is <br />anticipated that the deposited sediments can be sold for construction <br />material. <br />
