Pion, Wo.er Conservation MoJo ring <br />Client Contact: Carol Ellinghouse <br />email: EllinahouseC@bouldercolorado.gov <br />phone: 303-441-3118 <br /> <br />From 1998-1999, Hydrosphere was the lead consultant for a study that characterized Boulder's water <br />use patterns; updated Boulder's water demand projections; and reassessed the reliability of Bbulder's <br />water supply system given this new information. We developed appropriate water conservatioh <br />program alternatives given Boulder's water use patterns, reliability criteria, and other water-rel~ted <br />goals (e.g., instream flow preservation); evaluated those alternatives considering water savingS, utility <br />benefit/costs and revenue effects, customer cost effects and non-cost/public values factors; an1d made <br />recommendations to the City. <br /> <br />From 2001-2003, Hydrosphere was the lead consultant, in close partnership with Utilities staff, for <br />developing a guidance document for recognizing droughts that will affect Boulder's water supp~y and for <br />responding suitably to those droughts. We developed summary information on Boulder's water <br />supplies, categorized drought levels according to severity, developed detailed information on particular <br />actions that might be taken to respond to each drought alert level. We conducted detailed analyses of <br />the potential effects of previous and recent droughts upon Boulder's water supply system, inclJding the <br />CBT project system. While the Drought Plan was being developed, Hydrosphere helped Boulder in its <br />early recognition of, and effective response to, the 2002 drought. By late April, we accurately I <br />forecasted Boulder's water yields for 2002 and developed water use reduction targets for the upcoming <br />year. We developed a suite of demand reduction measures tailored to those targets and an e~ective <br />communication program to ensure their attainment. I n 1990 and from 1992-1993, Hydrosphere <br />estimated the demand-reducing effects and revenue effects of proposed changes to Boulder's Iwater <br />rate structure. We utilized Boulder's water billing database to evaluate the effects of proposed changes <br />to the City's water rate structure upon owner-occupied single-family residential customers. This was <br />accomplished by applying a water demand elasticity equation to the previous year's water use !patterns <br />of approximately 1,000 randomly selected residential customers under existing and proposed ~ater rate <br />structures. In a separate study, Hydrosphere evaluated the effects of Boulder's existing water I <br />conservation programs on average and peak demands using a time series "cascade" analysis of <br />historical daily treated water production data as the dependent variable and daily weather datal <br />demographic data, and customer account data as the independent variables. We also developed a <br />water user survey that was sent out to utility customers to assess the extent of customer partic pation in <br />water conservation measures. <br /> <br />Socorro-Sierra Regional Water Conservation Plan, NM <br />Client Contact: John Carangelo, Soccoro Soil & Water Conservation District <br />email: marion@flash.net <br />phone: 505-864-5904 <br /> <br />Hydrosphere was contracted by the Socorro Soil & Water Conservation District (teamed with DB <br />Stephens & Associates) to provide project management and technical analyses for the Socorr6-Sierra <br />regional water planning effort in central New Mexico. The Socorro-Sierra region is primarily rutal with a <br />few incorporated municipalities. Most municipal, industrial, and domestic water use is provided from <br />groundwater supplies while irrigated farmland is generally supplied by surface water diversionS. <br /> <br />Page 3 <br /> <br />
