<br />,~U) <br /> <br />...~ <br /> <br />Most of these "passive" zoning/development policy actions and technological advancements will <br />directly affect outdoor water use (i.e., urban landscape irrigation). With outdoor water use <br />accounting for a majority of urban use in many of the larger districts, these municipal ordinances <br />have an even greater potential for water savings than the aforementioned indoor appliance/fixture <br />replacement. Failure to include water savings estimates from these additional passive <br />conservation measures would result in an artificially-low conservation savings estimate and, as a <br />result, skew future demand projections.. <br /> <br />(3) Data reveal a steady downward trend in per capita water consumptiODa <br /> <br />The Smart Water study and other data indicate that in most cases system-wide M&I per capita <br />water use is decreasing at a substantially faster rate than the SWSI passive projections listed in <br />the Memo. We recommend further consideration and analysis be given to the passive <br />conservation estimates in SWSI. <br /> <br />The Smart Water report's Appendix B highlights changes in system-wide per capita consumption <br />in several southwestern cities over the seven year period from 1994 to 2001.. Many of the <br />documented reduction rates ranged from 9% to 19% over this period. The table below <br />summarizes this information (once again, as derived from data supplied by water providers in <br />our survey): <br /> <br />These demand reductions are five to ten times faster than the SWSI passive reduction rates. <br />While some of the system-wide use rate reductions in the Smart Water analysis resulted from <br />"active'') conservation in some of the cities, significant per capita water use reductions even <br />occurred in cities/districts that did not implement many active conservation measures during this <br />time period. In other words, passive conservation (indoor and outdoor) likely has the potential to <br />be much more significant than the initial SWSI analysis suggests (Memo, page 8). We feel that a <br />disparity of this degree warrants a closer look at conservation potential and demand projections <br />by urban areas across Colorado. <br />
