The site is located near the St. Vrain River in Weld County, <br />Colorado. Reservoir liners include compacted earthen embankment slope liners and soil-bentonite <br />slurry wall lining systems. In total, over 25,000 linear feet of liner will be constructed. Design <br />challenges include coordinating the reservoir construction with existing irrigation ditch facilities. <br />Eight existing ditches and irrigation laterals crossed the property. Relocation of ditch diversion <br />structures, design and construction of new laterals and diversions to fill the ponds, and <br />configuration of the reservoir layouts required careful consideration and coordination with ditch <br />company boards and individual lateral owners. <br /> <br />Federal permits, including U.S. Army Corps of Engineers' 404 permits were required. New diversions <br />to fill the reservoirs and interconnecting pipeline tunnels between the reservoirs were designed. <br /> <br />Final reservoir storage along with the filling and interconnect facilities will be owned by Central <br />Colorado Water Conservancy District. The projected total water storage volume will be <br />approximately 4,800 acre-feet <br /> <br />Client: Lot Holding, LLC <br />Project Cost: $2 million <br /> <br />Siebring Reservoir <br />Greeley, Colorado <br /> <br /> <br />Siebring Reservoir was lined with a 10/000-foot long soil-bentonite slurry <br />wall converting a mined gravel pit into a raw water storage reservoir. <br /> <br />file://X:\0290 Delta Sand & GraveI\04-0020 Pit Exnanslon\Hvc1nl~11r H~rripr\npprp ~ Alll <br /> <br />1 l/l/')(\(\h <br />
