Mr. James Maxfield BOOSTER PUMPING STATION In the existing booster station there are six pumping units each consisting of two Byrflrn Jackson 10 x 14 x 20 DVS pumps operating in series. Under present operating conditions water is lift ed from a reservoir at elevation 1400 to the terminal reservoirs at elevation 2038. Under the present operating conditions six pumping units will discharge about 36 million gallons per day against a total dynamic head of more than 800 feet. Without alteration or change these same pumps will deliver at least 50 million gallons per day against a toi^L dynamic head of 650 feet at little or no sacrifice of efficiency. At least 50 million gallons per day could be delivered to the site of the Manganese Ores plant at elevation 1836.5. PIPE LINE CAPACITY At a pumping rate of 50 million gallons per day the velocity in the existing 40 inch pipe line would be 8.8 feet per second. Such a velocity is not unusual nor is it inordinately uneconomical, particularly since the average pumping rate would be less than 50 million gallons per day. Pressure on the line would not exceed presently imposed pressures. PROPOSED SECONDARY BOOSTER PUMPING STATION At the Manganese Ores plant the water would be delivered to a junction reservoir, either new or made by altering one of the existing Dorr thickener tanks. A new booster pumping station would lift the water 201.5 feet from the junction reservoir to the terminal reservoirs at Henderson. Supply to Manganese Ores would be taken from the discharge side of these booster pumps, ? PROPOSED PIPE LINE TO LAS VEGAS From the junction reservoir at elevation 1836.5 all water not taken by the industries would be available through a gravity flow pipe line to a standpipe located near Charleston Boulevard at ground elevation 1750.0. This would be on a direct route across the easterly valley fan and it would be a relatively low pressure line. Domestic water would be boosted from this point into the domestic water distribution lines. Water would also be available, if required, for potential agricultural land in the lower valley. EMERGENCY WATER EXCHANGE Supplemental water from Lake Mead would make possible a stabilization of the subterranean reservoir which underlies a large area of the Las Vegas Valley. By reverse flow through the proposed Las Vegas pipe line, water from the underground basin
