<br />. <br /> <br />. <br /> <br />Method: Existing base maps developed by various entities or jurisdictions will be <br />assembled and integrated. The Northern Colorado Water Conservancy District <br />(NCWCD) will contribute in-kind services to developing the composite map with the <br />assistance of the other participants. The NCWCD will assist in merging pertinent GIS <br />coverages that are currently not in its GIS database set for the region, <br /> <br />TASK 2, Develop an engineering and management checklist (rating svstem) that will help <br />agricultural irrigation water suppliers better assess their potential for dual system development. With the <br />possible assistance of their legal and engineering council, these entities could use this checklist to conduct <br />an inexpensive assessment of their own capability before making a final decision about entering into dual <br />system management. The checklist will include simple and useful ways to evaluate water supply needs, <br />present and future demand for dual system service, liability and water rights concerns, financial <br />considerations, and the overall condition and retrofit needs of the irrigation system for dual system <br />management. The task will include a sample application and evaluation of the checklist to approximately <br />ten volunteering agricultural water suppliers in Water District 1,2,3,4,5, and 6. <br /> <br />Method: The checklist will be developed and applied with the assistance and advice of <br />agricultural irrigation water suppliers in the study area, Colorado State University will <br />assist in developing this checklist with its faculty and student support, along with the <br />assistance of other study team members. <br /> <br />TASK 3. Conduct a water supplv and demand analvsis based on regional water supply, the price <br />of water, population projections and patterns of water use. The analysis will also include an updated <br />inventory ofC-BT units and native water supplies in Water District 1,2,3,4,5 and 6, aggregated by <br />regional jurisdiction and agricultural ownership, The task will update population estimates for <br />unincorporated areas and projected population growth in these water districts. The task will include an <br />estimate of current and future demand for pressurized untreated water in unincorporated areas, what <br />percentage of treated supplies for landscaping needs might be met by dual systems, patterns of <br />consumption for various types of subdivisions and land use (rural estate uses, hobby farming, strict <br />residential, xeriscape landscaping, industrial/commercial), and an assessment of covenants, ordinances <br />and zoning that may be expected to affect water supply and demand for non. farm use in unincorporated <br />areas. <br /> <br />Method: An update or revision ofNCWCD's Water Demand Study will be used, along <br />with information provided by rural domestics on current and projected demand for <br />potable water, under "without dual systems," "with dual systems," and selected other <br />scenarios, The more detailed Part II analysis involving the two sample irrigation <br />companies (see next section) will be used to prorate specific supply and demand <br />coefficients or values for various types of irrigated agriculture and non-farm uses in <br />incorporated and unincorporated areas throughout the larger region. Groundwater supply <br />will be assessed by other participants using existing water rights tabulations, Information <br />from municipalities and counties on water consumption and land development policies <br />will be used to create different long-term consumption scenarios. <br /> <br />TASK 4. Conduct a development cost analvsis that will include an estimate of installation costs <br />and basic engineering requirement of dual systems for agricultural water suppliers serving standard.sized <br />subdivisions, and applied to both new and retrofitted subdivisions, metered and non-metered delivery, <br />seasonal versus annual service, and the use of existing versus new additional storage for pressurization. A <br />sample breakdown will be given of costs and engineering based on similar installations in other localities <br />were dual system are presently operationaL The task will also discuss how these systems are normally <br />
