Letter from L. R. Maag (Los Angeles) to William Reinhardt, February 6, 1952

Los Angeles, February 6, 1952 1-7334 Mr. Wm. Reinhardt: (CO - Mr. E. C. Renwick Mr. R. L. Adamson) In connection with study of State permits for Appropriation of water from wells at Las Vegas, Nevada, Mr. Renwick has raised the question as to whether the so-called "Shop Well", located in Railroad Company shop grounds near Round House, could be utilized to fill R. R. Co. requirements in event the Las Vegas Water District takes over the existing R. R. Co. transmission mains. The following data on Shop Well and flow through meters is submitted for consideration: Shop Well requires a pump. Measurement on January 8, 1950, indicates a flow of 301 GPM, or 433,400 GPD when pumping into top of water softener with 25# pressure at pump, or 65# pressure at pump when pumping against a closed valve. This flow would, no doubt, decrease substantially with continued use since this well had not been used for several months prior to above measurement. Shop Well constructed 1920-21. Casing - 0' - 236' is 12* iron Double X 236' - 780' " 10' ' * ' Perforations - 6 per 10' - 280' to 290' 6 ' 10" - 590' ' 594' No filing made with State Engineer. Plow through meters serving R. R. Co. facilities and industries in 1951 was. as follows: Year 1951 Month of July 1951 Name of Meter Total for Year Gallons Average C.F.S. Total in July-Gallons Average Gale.

The balance of the meters, which includes the old Stock Yards, Power House, Tank Cars and Water Softener meters, are so situated that they could be disconnected from the 24" main which now serves them and connected to a new line which might be constructed from the Shop Well. The flow through these meters In July 1951 was 5,391,500 gals., or an average of about 130,000 gals, per day, or an estimated peak flow of 200 GPM. However, if a plan is considered to utilize the Shop Well for service to lines served by meters as outlined in paragraph above, it would be necessary to provide additional facilities as roughly outlined below in order that such a plan would function properly and provide uniform pressures, which could not be obtained by connecting existing lines to a pumping well. Elevated steel storage tank on 60' high Rough Est. (a) C<Mt tower with not less than 200,000 gal. capacity, $40,000 Note: Automatic pressure system with pumps and tanks could be substituted stituted for elevated tank, but is not recommended, due to operating ing difficulties. (b) Rearrange existing lines and construct new lines to transfer source of water from existing isting mains to Independent new system connected nected to operation of Shop Well, 10,000 Note: Existing connection with meter from Shop Well to 24" main should be left in place so that water would be (c) available in event of well failure. Construct sand trap, 1,500 Contingencies, &.PP9 - $57,000 In addition to above data, the following considerations should be taken into account: (a) The well is 32 years old, and probably in poor condition as to casing, etc., which would, no doubt, make inadvisable the reconditioning of well or reperforation of casing. (b) Pump and pumping equipment are estimated to be 20 years old. (0) The Railroad Co. would still be in the water business to a limited extent. (d) It is very doubtful whether the capital expenditures and future maintenance coats would be economically justified. Recommendations: (1) Arrange with State Engineer for transfer of existing 2.5 Sec. Ft. appropriation allotted for R.R.Co. purposes at Well or a portion thereof, from Well %1 to R.R.Co. "Shop Well". If State Engineer will not approve transfer of this 2.5 Sec. Ft. allotment, or any part of it, then secure a new appropriation for required water at 3hop Well. See tabulations under Item (3), Paragraph 1, of this letter for amount required. (2) Use Shop Well to furnish water to R.R.Co. Water Softener only through existing lines. Connection from Shop Well to 24* main, Including meter, should remain in place to furnish stand-by supply in event of well failure. 3ervlce from Shop Well to Water Softener will not require a pressure system or elevated tank. (3) In event of sale of water production facilities to Water District, arrange to purchase all water required for R.R.Co. facilities, with exception of Water Softener. The Railroad facilities referred to above are, as follow*: Consumption During 1951 Gallons Stock Yards (Old) 1,636,700 *Power House 13,239,300 Tank C&r* 4,259,700 Coach Hydrant 7,617,900 R.R. Rooming House 2,549,200 New Stock Yards 92.100 29,594,900 - Av. 0.125 CFS * Includes service to Company owned houses. The P. F. E. Co. and other Industries now served by R. R. Co. through meters to make arrangements direct with Water District for service. (Sgd) L. R. Maag L. R. Maag
