The lining <br /> <br />and rehabilitation of existing distribution systems and the construc- <br /> <br />tion of new systems, where required, to deliver project water to lands <br /> <br />served would need to be accomplished and financed by local water-using <br /> <br />entities or by the Bureau of Reclamation under separate rep~ent <br /> <br />contracts. <br /> <br />The project functions to be served under present conditions are the <br /> <br />same as those proposed in the 1947 report, but the magnitude and re1a- <br /> <br />tive importance of these functions have changed materially. In the <br /> <br />1947 report, it was proposed that about 1 percent of the total water <br /> <br />supply would be allotted for municipal and industrial purposes; <br /> <br />whereas, this reanalysis contemplates that approximately one-third of <br /> <br />the assumed project water would be assigned to municipal and industrial~ <br /> <br />uses. The new water supply studies have recognized the need for con- <br /> <br />servation and use of the large quantities of usable return flow that <br /> <br />will be available from the projected municipal and industrial water <br /> <br />systems. Such return flows would have the effect of augmenting the <br /> <br />potential import water supply and increasing the overall efficiency of <br /> <br />use; however, the limited scope of this supplement did not permit the <br /> <br />evaluation of these potentialities. Full consideration has been given <br /> <br />to the multipurpose operation of all project reservoirs for flood <br /> <br />control, recreation, fish and wildlife, and other purposes, in <br /> <br />recognition of the increasing magnitude of potential flood damages and <br /> <br />8 <br />
