(COPY) Omaha -,November 37, 1934 353-34 Mr. H. C. Mann: Las Yggas Land & Water Company W. O. 241 covers renewal of 3530 feet of wood stave pipe with cast iron pipe in Hawkins Addition, at Las Vegas. These pipe lines in Hawkins Addition were purchased in 1928, and at the time this purchase was made Mr. Bracken advised as follows: ”The maintenance costs on the wooden?mains should be a negligible item .for fifteen or twenty years,'as they are now bound spirally with No. -8 wire of copper composition, whereas plain No. 1 iron wire was used on our water mains installed in 1905, 1907 and 1910. The new mains are also protected by an asphalt-sawdust coating.1' Upon taking up with Mr. Bracken as to why these lines now require renewal>in- view of his previous statement, he advises as follows; | "Original Redwood pipe laid in Clark's Las Vegas Townsite in 1905%and 1907, bound with No. 1 iron wire, without asphalt coating, was replaced during winters of 1924 'andL 1926, respectively, or period from nineteen to twenty years. Pipe purchased in Hawkins Addition installed early 1923' bound with No. 6 popper composition wire coated with asphalt which Pacific Tank and Pipe Company , claimed had life twenty-five years. In view of fact that inferior grade of pipe installed in 1905 and 1907.lasted nearly twenty years and the improved pipe in HawkinS' addition had been in ground only five years, we estimated the remaining life to be from fifteen to twenty years. However, it is evident that the chemicals in the soil in this particular district have destroyed both wire. and wood until at present the maintenance cost is prohibitive apd for this reason I have recom­mended replacement with cast iron pipe which under normal conditions should last fifty years." Will you please have this thoroughly investigated and advise fully as to necessity of renewing this wood pipe line at present time after a life of only eleven years, and if Mr. Bracken's' statement is*correct, .just what the soil
