Section 2 Conservation and Efficiency Technical Roundtable In addition the impacts of climate variability on water conservation and system reliability have not been addressed by this TRT. The following conclusions and recommendations are made by CWCB staff after a review of the Water Conservation and Efficiency TRT efforts. The primary areas where there is a lack of consensus among TRT members is on the successful implementation of some of the conservation measures, especially turf replacement and the role of water conservation in eliminating the need for structural projects and processes that water providers have planned to meet future water demands. Potential Impacts of Water Conservation on Supply Reliability and Potential Uses of Conserved Water 1. Issues related to conservation and reliability are specific to each utility and dependent upon the portfolio of water rights (type and priority). 2. Water planners are strongly encouraged to analyze safe yield and develop reliability criteria for their systems. Water providers should evaluate the actual impacts of conservation on system yields and reliability through model runs and reasonable assumptions about technological and behavior savings that may be expected from customers during droughts before and after the implementation of conservation measures. 4. The impacts of the implementation of water conservation measures on the reliability of water systems should be examined based on the potential uses of the conserved water, such as new growth, instream flows, drought reserve, or lease or sale to other entities. 5. The use of a portion of conserved water for new growth or drought reserve by the conserving utility appears possible under most circumstances without impacting reliability. 6. The use of a portion of conserved water for environmental flows also is feasible, especially if the water is subject to a pull back by the utility during drought or other water shortages. Some conserved water, such as from in-basin direct flow rights, may have limitations if transferred to an environmental flow. At this time, based on extensive utility feedback, it is very unlikely that any utility would permanently sell conserved water to another utility. 8. When evaluating demand reduction, it appears that some additional water savings can still be FINAL DRAFT 2-23 Example of Low Water Use (25% Bluegrass) Residential Landscaping WaterWise Landscaping Trees, Shrubs £t Vines Jim Knoof.
