<br />CHAPTER 1. MUNICIPAL WATER <br /> <br />Present Use <br /> <br />Quantity <br /> <br />About 987,900 people, 70 percent of the state's 1960 population,lI <br />are supplied with water distributed by central water supply systems, <br />hereafter referred to as municipal systems. The rest, 424,000 people, <br />obtain their water from individual systems which are discussed in Chapter <br />3. The present annual usage through municipal systems is about 183,100 <br />acre-feet, an average of about 163 mi llion ~al Ions per day (mgdl. This <br />averages 165 gal Ions per capita per day (gpcdl. <br /> <br />These estimates are based upon data of normal usage by about 270 <br />systems~ and the assumption that the normal per capita usaOe of other <br />systems equals the future per capita municipal water use rates establ ished <br />for planning purposes. <br /> <br />Since 1960, the population has continued to shift from rural areas <br />to urban areas and new central supply systems have been instal led, <br />further increasing the number of persons supplied through municipal <br />systems. This situation is expected to continue throughout the projection <br />period. The projection of future usage takes these shifts into account. <br />Table 1 shows present municipal usage by basins. <br /> <br />Municipal water systems supply water for various functions including <br />household use; fire protection; street cleaning; irrigation of lawns, <br />gardens, parks, and golf courses; Vlatering livestock; and manufacturing. <br />These fall into broad classes referred to as domestic, agricultural, and <br />industrial. The division of water usage between these classes was not <br />attempted. Therefore, municipal water as used in this discussion is <br />al I the water supplied through a central public system. <br /> <br />3/ <br />Records of the Nebraska Oepartment of Health- show that on <br />January 1, 1969, 463 cities, towns, and vi I lages were served by water <br />supply systems. AI I but Omaha, Chadron, and Crawford obtain their <br />supplies from ground water sources. Omaha has recently developed a wel I <br />field in the Platte Val ley to supplement its surface supply. Chadron <br />developed a wel I field in 1969 and wi II eventually abandon its surface <br />supply. <br /> <br />1/ Unless otherwise noted, al I population data referred to in this <br />volume as "1960" or "present" is taken from 1960 data of the <br />U. S. Bureau of the Census. <br /> <br />~ 1963 Inventory Municipal Water Faci I ities - Region VI, Public <br />Health Service, U. S.
