The percent reduction indicated for Levels 2 through 5 is "above and beyond" the Level 1 reduction; the cumulative percent reduction is shown in parentheses. Note that emergency conservation programs and short- term drought-response restrictions are not included among these long-term water conservation programs. Temporary drought restrictions include requests for voluntary demand reductions or mandatory water use restrictions during drought conditions. This type of demand modification usually involves drastic, temporary behavioral changes such as not watering the lawn or washing the car. Droughts can also result in permanent water conservation benefits, such as retrofitting indoor plumbing devices with more efficient water saving devices or reducing or eliminating high water use landscaping. During the most recent drought, it was reported that mandatory restrictions resulted in short- term water demand reductions of 20 to 30 percent (Kenny and Klein 2004). . Level 2 (Basic) M&I Conservation: This level of conservation consists of programs for metering and leak detection, and can generally achieve about a 4 percent water demand reduction in addition to the passive conservation reductions. It is assumed that water providers would continue to fund programs to S:\1177\BASIN REPORTS\NORTH PLATTElS9_NORTH PLATTE. DOC maintain this level of savings in future years, thus the estimated percent reduction is a steady percent . Level 3 (Moderate) M&I Conservation: This level of conservation typically includes programs for metering and leak detection, education, rebates for water- efficient toilets and washers, and a rate structure that promotes effective water use. This level of effort generally corresponds with implementation of the nine water conservation measures recommended by the CWCB for consideration in Colorado water conservation plans. This level of conservation can generally achieve about 5 percent water demand reduction in the short- to mid-term (10 years). . Level 4 (Aggressive) M&I Conservation: This level of conservation typically includes programs above and beyond moderate conservation, including steep pricing rate and surcharges, rebate for landscape changes, residential and commercial audits, turf replacement and restrictions, rebates for irrigation sensors and controllers, sub-metering of master- meter properties, and fixture retrofit upon sale of properties. This level of conservation can generally CONI 9-3
