V 2 3 - Install a new receiving basin and a new booster pumping station near the Manganese Ores plant for final delivery of water" o the terminal reservoirs at Henderson. The pumps and motors now installed at the intake, with columns and one bowl removed, precise­ly fit the conditions at the proposed new booster pumping plant. The proposed receiving basin would be so constructed that it would supply gravity water to the Las Vegas area and to the booster pump suction header. However, the connections would be such that prior­ity in rights would always be available to the Henderson industries. Also, the piping and valves would be so arranged that the receiving basin could oe by—passed and delivery made directly to Henderson exactly as is now being done. This method of operation would no doubt be used throughout the cool season when Las Vegas water con­sumption is low. The estimated cost of the reservoir and booster station is #218,100. 4 - Construct a new 48“ gravity pipe line from the reservoir in the vicinity of the Manganese Ores plant for delivery of water to the Las Vegas area. The pipe line would also be used to deliver water back from the Las Vegas area to the Henderson industries in emergencies. The estimated cost of the new pipe line is #1,864,900. _ p “ Provide 30 million gallons of additional storage capa- suSSes"ted that this additional capacity be located in the Las Vegas area at an elevation which would make it available by gravity either to Las Vegas or to the industries at Henderson. How- ever, this additional storage could be located near Manganese Ores or at Henderson and still be of value to all interested parties. The estimated cost of the new storage facilities is #840,000, 6 “ Install additional transformer capacity at Henderson and at the existing booster station; install new transformers, switch gear and appurtenances at the proposed new booster station; and, in­stall a new underground cable from the existing booster station transformer bank to the intake* No change would be necessary in the starting and control equipment at intake other than to replace the existing current transformers. The estimated cost of all electrical work is #377,700. The estimated cost of the entire project, as outlined herein des2ribed more fuHy In the accompanying bound "INTERIM RE­PORT , is #3,475,000. This estimate is subject to revision before presentation of the final report but, unless unforeseen contingencies develop, it will not change materially. When complete, the plant would be first class in every way and, even if it were being designed new for its intended use, it is doubtful if it would differ materially from the Dlan recommended.
