V LOS ANGELES - July 25, 1944 (CC - Mr. B. H. Prater Mr. R. L. Adamson) At your request an investigation was made by Mr. R. L. Adamson and myself of the water conditions of the Las Vegas Land and Water Company's system at Las Vegas, The wells and springs at Las Vegas (exclusive of the Union Pacific Railroad Company well near the round­house) have a capacity of 9339 gallons per minute or 13.448.000 gallons per day. The water is collected in a 2.500.000 gallon reservoir about two miles west of Las Vegas. From the reservoir the water is transmitted to the City Pipe Distribution System in two pipe lines. One pipe line 24 inches in diameter extends from the reservoir to Clark and Main Streets. The other pipe line which is half 24 inch pipe and half 16 inch pipe extends from the reservoir to Ogden Street. Meters are located at the end of each of these lines on the railroad right of way. There are two Booster Pumps at the reservoir by which the pressures at that point can be raised from 8 to 18 pounds according to the quantity of water pumped. When pumping, the pressures at the two meters near Ogden and Clark Streets range from 20 to 54 pounds acqordl.ng to-the amount of water pumped. The pressure at these two meters is increased about 10 pounds when the pumps are started. ^Mr. Frank Strong: We made a number of tests of the pressures and quantities of water delivered to the City Distribution System with and without the pumps in operation. At 5 P.M. on July 19th, which is the time when the heavy flow to the City begins and shortly after the pumps are put in operation, the quantity of water flowing from the reser­voir without the pumps operating was 7761 gallons per minute. When the pumps were started 8894 gallons per min­ute were pumped from the reservoir at a pressure of 13 1 /2 pounds. This indicates that the pumps are now a material factor in increasing the pressure and quantity of water delivered to the City Distribution System. The largest JULW .2H5 .1J.944
