<br />The usage datai/ show wide differences in amount of wnter per <br />capita per day withdrawn by municiral systems with the hi~h being 397 gpcd <br />and the low 40 gpcd. The extreroes are not confined to any rarticular <br />area. All basins show wide differences in per caritil uSiJ~Je. In the <br />I istin~ are 47 systems showin~ usa~e rates of less than 80 gpcd, iJnd <br />35 with usage rates of more than 200 gpcd. The average usa0e rate for <br />the approximately 270 systems inventoried is 178 gpcd, with systems <br />serving communities of less than 2,500 persons avera~ing 140 gpcd, <br />those serving 2,500 to 10,000 persons averaging 161 grcd, and those <br />serving over 10,000 persons averaging 192 gpcd. Reported and estimated <br />water usage for municipal systems by stream reaches is included in <br />Attachment 1. <br /> <br />Standards for future municipal per capita water use rates estab- <br />I ished by the Nebraska Soi I and \'/ater Conservation COr:lmission for plan- <br />ning purposes are shown in Table 2. The amounts vary by size of com- <br />munity and location within the State. The P.l.
