Cottonwood Water&Sanitation District Agenda Item 30a <br /> May 9,2014(Updated May 23,2014) <br /> Page 5 of 7 <br /> Borrower- Cottonwood Water& Sanitation District <br /> In 1981,the Cottonwood Water& Sanitation District was formed, pursuant to Title 32 C.R.S.,to <br /> provide water supply and treatment systems for customers within its service area. In 1996, the Board of <br /> Directors passed a Resolution establishing a water activity enterprise. The District meets the <br /> requirement for a state-approved conservation plan by virtue of its participation in the cooperative <br /> Douglas County Water Conservation Plan, which combines the individual conservation plans of 15 <br /> regional water providers into a single document. <br /> The District contains approximately 1,300 acres, located along the northern border of Douglas County. <br /> Approximately 2/3 of the District is within the Town of Parker and the remainder is in unincorporated <br /> Douglas County. Currently it supplies water to a total of 2,300 single family equivalent(SFE)taps. <br /> In 2013, the District supplied a total of 789 acre-feet of water to its customers, equating to an average <br /> 705,000 gallons per day. The highest daily usage recorded for 2013 was 1.4 million gallons. Currently, <br /> the District's water supply is provided through tributary water rights from Cherry Creek, and non- <br /> tributary water from the Denver Basin(Arapahoe aquifer). Both of these water sources are reusable by <br /> right. The District reuses much of its water supply. Including Cherry Creek alluvial supply water <br /> rights, the District has access to 2,456 acre-feet annually. <br /> The District estimates that through the importation of additional renewable water through the WISE <br /> Project, most of its water supply in average and wet years will come through its renewable water <br /> supplies (Cherry Creek tributary water rights, WISE deliveries, and reuse). In these years,the District <br /> will store excess WISE water in its non-tributary aquifers or in Rueter-Hess Reservoir. In dry years, <br /> when WISE deliveries are curtailed or when alluvial supplies on Cherry Creek are diminished,the <br /> District will rely more heavily on non-tributary ground water pumping and deliveries of WISE water <br /> from storage. <br /> Water Rights <br /> The District has 1,690 acre-feet of non-tributary ground water rights, and 766 acre-feet of Cherry <br /> Creek tributary water rights. The District currently only has non-tributary wells in the Arapahoe <br /> Aquifer with an entitlement of 1,003 acre-feet. The District's 766 acre-feet of tributary water varies <br /> from year to year. All water rights are reusable and the District is able to effectively reuse its water <br /> rights to replace out-of-priority depletions per its decreed augmentation plans on Cherry Creek. <br /> Borrower's Participation <br /> Cottonwood has subscribed to 400 acre-feet of water on an average annual basis through the WISE <br /> Project. <br /> Cottonwood's local project infrastructure components will extend from an existing tee located on the <br /> ECCV Western Pipeline, where a below-grade vault with flow control and metering equipment will be <br /> installed. From this location 500 feet of 36-inch pipe will be installed to connect to an existing <br /> Cottonwood pipeline. In addition, Cottonwood will also participate in a Rueter-Hess Reservoir fill <br /> pipeline and pump station being constructed by Parker. <br /> The estimated total project cost for all of the WISE Project components is $147.5M. The amount that <br /> each WISE Authority member is required to pay depends on the amount of water each WISE Authority <br /> member has committed to taking, as well as the amount of local infrastructure that must be constructed <br />
