'380G 4 METROPOLITAN WATER DISTRICT pumping units in each pumping plant, the construction of the second and third pump delivery lines at each plant and the construction of the second 230 KV transmission line from Hoover Dam, This work was all completed early in 1960 and provides the facilities for the delivery of the 1,212,000 acre-feet annually of Colorado River water Hllotted to the Metropolitan Water District. The expansion program also included additional distributing lines, storage reservoir capacity and water treatment facilities, When the work was started in 1952 there were 214 miles of lines, including the 36 miles of the first barrel of the First San Diego Aqueduct. DUl'ing the last nine years there has been 216 miles of lines, including 64 miles on the two San Diego Aqueducts, added to the system for a total of 430 miles, The 1.500 acre-feet capacity Garvey Reservoir and the enlargement of Lake Mathews from 107,- 000 to 182,000 acre-feet capacity have been completed and added to the system, Other expansion program features being constructed but not yet completed at the end of the fiscal year are the add ition of 200 mil- lion gallons a day capacity to the F, E. Weymouth Softening and Filtration plant at La Verne for a total capacity of 400 million gal- lons a day and the new 200 million gallons a day water treatment plant on the Lower Feeder near Yorba Linda, California, At the end of the year the Colorado River Aqueduct system rep- resents an investment of approximately $467,000,000 and if all the work had been done at present day prices the cost would have been more than $1,000,000,000, All construction and operating costs of the Colorado River Aqueduct system have been and are being met by the taxpayers in the District, There never has been any Federal snbsidy of this domestic water supply, The people served by the aqueduct have paid for all costs and, based upon past experience, they are prepared to pay their way for any future development of new sources of water supply that may be required to meet the in- creasing demands for water, The accompanying Table 5 shows the annual delivery of Colorado River water, It can be readily seen that the use of water is rapidly approaching the 1.212,000 acre-feet an- nually allotted to the District from the Colorado River and before that maximum is reached it is hoped that additional water may be available from the northern part of California through the aqueduct authorized for construction by the $1.75 billion bond issue approved by the electorate of the State of California in 1960, J Wale" Shorta!!e Between 1940-41 and 1948-49 there were only 146,232 acre-feet of Colorado River water delivered to the water agencies of the Dis, trict as shown on Table 5, This was accomplished by the operation of a single pumping unit at each of the five pumping plants although there were three pumps operative in each plant that could have (;tdivered more than 0,500,000 acre-feet during that time.
