~ ~ . . . i'lpp.,'aisal Stage The specific work items to be performed for this stage are listed. The iterns are generally listed as they will occur in time but some of the items can be conducted concurrently or will overlap with other items. l"his stage could be conlpleted in 2 months. . 1) The first step is to estimate the water requirements of the District now and in 10, 20 and 30 years. The District nlanager has fairly gc'od information on the ~aximum number of potential units and the t.ate which the units are peing constructed. lOhe data on the number of possible llnits ar)d the current per capita water usage will be used to estimate tire pt;)pulatiorr arId the .....esultirlg water" requirement at each peric1d in the future. The water requirement will be estimated in terms of acre-feet over a time period and flow in cubic feet per second; the time periods will include~ one year, peak rl1orlth, peak day and" pe.:...=d< hour'. The storage c,":\pacity of the existir:g tanJ(s will be utilized to redLtC@ the peak flow from tne water sout~ce. The Districts ability to ~epay will be determined based upon their revenues from exisiting sources and the potential to increase revenues. The prima~~y sources ~ow are property tax and water/sewer cha'r~ges. athey' subdivisiorls in the gerlet"'al al"~"ea, (e. g~ D1xr"'ango f'llet"('o District #1) will also be contacted to determine if there is any potential for the project tel pr6vide water to them as well. Mett"'o District #1 is inlmediately 6dJ3cent to Distt~ict #2 and could easily be inclLtded in the stlldy; tt,eir inclusion will not change the potential alternative plans but would increase the potential water dernaY"ld.. 2) A Shr:lt~t (oi~le Or"' two page) desct"'iptioYI, with a map a"no construction costs, operation costs, and a summary of the advantages versus disadvantages, will be prepared for each of the alternatives. The descriptions will be preparQd for use by the District Board and the ewes in selecting the best optio~. The possible alternative plans wC;ljld incll.tde: Wells - "rhe District presently receives all of its water from wellsi however, these wells are slowly decreasing in yield. The potential yield of new wells will be addressed particularly as an interi~l solution if the best option cannot be constructed for several years. Several studies have been per~formed regarding the wells and these will be utilized In the evaluation. Also, if nE-?c8s!:::.B"r"'Y, an expet-.ie}-".ced geohydrologist (e.g. Tim DecJ(er of Westwater ASSoclatesl ffiay be utilized to evaluate the wells. . > Lightner Creek - "l-he DistT~ict presently h,~lds wdtet~ rigtlts I~n the Creek but to tap the ct'eek a lonu pipeling with several punlps ~~oljld be requi~"'ed. l-he faciliti2s and the diversion method will be planned o~ USGS Quad maps.
