About that time the wood pipe began tjo be expensive to main­tain on account of termites, and penetration by tree and shrub roots. All w o o d pipe and wrought iron pipe In the entire system has been re­p l a c e d w i t h cast Iron, the greater part of thej replacements being carried out in 1941. The change will eliminate the former losses of w a t e r due to leakage in the mains. It also will reduce future mainte­nance costs to a minimum. Me t e r s are not permitted under a state 1 aw affecting Cxties of over 4,500 population, and there is a prodigal use of water, partic­ula r l y d u r i n g the heated term when very high temperatures prevail. The l o w wat e r p r e ssure resulting from the gravity jsystem - ranging from 35 to 20 po u n d s - has had a bearing upon the waste observable In sprinkling lawns; a n o t h e r removable item of loss has bedn seen in negligent opera­tio n of air c o n d i t i o n i n g apparatus, of which there is much in the city. From time to time the attention of the public jhes been directed by ad­vert i s e m e n t s in the city newspapers to the wadte of water by consumers, and such educational work will, it is hoped, produce lasting results. There is a city ordinance relating to wasteful use of water, passed in July, 1939, but it has not been enforced. Ladt year, however, the city assigned a special uniformed officer during trie heated term to look after the wa s t i n g of water by any and every mdans, and the LVLandWCo. p a i d one half of hie salary. The results were) very satisfactory. The LVLandWCo.'s water rates conform to a schedule fixed by the Public Service Commission of Nevada and mdde effective on Sept. 1, -7-
