<br />NTM CWCB Water Conservation Plan Grant Application <br /> <br />Rage 5 of 11 <br /> <br />There is a great deal of uncertainty in predicting the timing and amount of future water <br />demands as the majority of land is in unincorporated Jefferson County and de~elopment <br />depends on the interests of buyers and sellers. Based upon historical developl1}ent rates, <br />NTM estimates population growth to average 3% per year, though for the 200(i) through <br />2006 period the average annual growth rate was nearly 4%. Using NTM's 200:6 service <br />area population as the baseline and assuming a 4% annual growth rate, NTM v ould reach <br />it's build out population of nearly 30,000 in 2035 as shown in Table 4. <br /> <br />Table 4: NTM Service Area Population Projections <br />Service Population <br />Estimate <br />9353 <br />10942 <br />13312 <br />16196 <br />19705 <br />23975 <br />29113 <br /> <br />Year <br />2006 <br />2010 <br />2015 <br />2020 <br />2025 <br />2030 <br />2035 <br /> <br />(c) Estimated water savings goals to be achieved through implementation of the <br />Plan: <br /> <br />North Table Mountain Water and Sanitation District is required through its contract with <br />Denver Water to implement water conservation measures at least as restrictive I as those <br />required by Denver Water. Historically NTM has imposed more stringent water use <br />restrictions. As Colorado's population continues to increase, NTM is committJd to <br />ensuring that water is used efficiently and wisely by its service area populatiori. With <br />less than half of its potential service area developed, NTM recognizes that its tater <br />supply may prove inadequate. A well developed Water Conservation Plan will help <br />manage current demands as well as plan for future development. l <br /> <br />Using the gpcd values from Table 3, NTM service area residents have shown t at they <br />can decrease their water use from 278 gpcd in 2000 to less the 200 gpcd during periods of <br />drought. NTM has developed a preliminary water use target of 185 gpcd by tHe end of <br />2015 for its water conservation plan. This goal was selected as a minimum w~ter savings <br />target which will be reevaluated during Water Conservation Plan developmentl The <br />nature of development in NTM's service area is changing and the number of cbmmercial <br />accounts is increasing. New residential developments tend to have more manibured <br />lawns and irrigated common areas and new commercial developments are chadging water <br />use patterns. Given the changing nature of its service area, NTM proposes to Jse the <br />Water Conservation Planning process to more fully evaluate the impact new add planned <br />development is having on per capita water use prior to setting an unrealistically low water <br />savings target. NTM is committed to encourage the efficient use of its water r~sources. <br />As specific conservation measures and programs are evaluated during Water I <br />Conservation Plan development, this preliminary water savings goal willlikel}j' be <br />adjusted. If all service area and land west of Highway 93 were completely built out (at 3 <br />houses per acre and 2.62 people per household), a goal of 185 gpcd would resJlt in a total <br />
