Use of plastic pipe with its <br />lower cost for both purchase and installation has greatly increa$ed the <br />possibilities in this regard. An important facto:r connected with installa- <br />tion is that plastic pipe is not readily subject to failure by freezing. As <br />indicated previously, any spring with a dependable yield in excess of 1-2 <br />gpm generally will have a surplus supply over that needed in the immedi- <br />ate vicinity. By use of pipeline, this surplus can be used in establishing <br />additional range water facilities when conditions are favorable for distri- <br />bution. Assuming that stock water supplies are to be spaced at 1-3 mile <br />intervals, use of pipelines becomes feas ible when the 'cost of a pipel ine of <br />this length is less than the cost of an alternative supply, such as develop- <br />ment of a well or construction of a stock pond. Furthermore, distribution <br />by pipelines or hauling may be the only means by which water can be pro- <br />vided in some localities. S i z e of plastic pipe needed for distribution <br />and the method and cost of installing pipelines are available from manu- <br />facturers and engineering handbooks so that cost compar isons with other <br />types of water development can be made. <br /> <br />. ,:.'..~ <br />~~~}~j~~ <br />."."","-'; <br />~~<~~m: <br />;/,".I.;/'.W:~ <br />::~~?~!f~ <br /> <br />;:;>:_~..,;.:, <br /> <br /> <br />~~ <br /> <br />8 <br /> <br /> <br />~ <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />""""& <br />:;f-:~""':f.: .' <br /> <br />Ordinarily, distribution by pipeline is considered feasible only <br />with gravity flow but in some instances a moderate pump lift to place <br />water at a desirable location for gravity flow may be entirely practicable. <br />Methods of pumping and costs for this type of pumping are also available <br />from handbooks or engineering texts, thus making it pos sible to compare <br />distribution in this manner with other methods of supplying water. <br /> <br />Hauling water from springs where surplus supplies are available <br />is attaining greater importance due to the extension and improvement of <br />ra,nge roads, and increased efficiency of hauling equip,ment, and to other <br />advantages relative to both the range and the livestock. Additional details <br />on hauling water are given in a later section. <br /> <br />In most States, unu sed supplies of surplus flow from springs are <br />legally available for use in other locations even though the spring is located <br />on privately owned land, provided proper easements and right-of-way are <br />obtained. This ruling is based on the principle that water is the property <br />of the State and is available for individual use only where it is legally <br />appropriated and so long as it is, properly us ed. Thus, unu sed or improp- <br />erly used water can often be claimed regardless of its origin or location. <br /> <br />
