LVLandWGe. used wood stave pipe exclusively in new eonstruotIon and replacements until 192?, when oast iron pipe was introduced into the system. About that time the wood pipe began to be expensive to main­tain on account of termites, and penetration by tree and shrub roots. All wood pipe and wrought iron pipe in the entire system has been re­placed with cast iron, the greater part of the replacements being carried out in 1941. The change will eliminate the former leases of water due to leskage in the mains. It also will reduce future mainte­nance costs to a minimum. Meters are not permitted under a state law affecting oitlcs of over 4,600 population, and there is a prodigal use of water, partic­ularly during the heated term when very high temperatures prevail. The / low water pressure resulting from the gravity system - ranging from 35 / . / to 20 pounds - has had a bearing upon the waste observable In sprinkling lawns; anothei* removable item of loss has been seen in negligent opera- I tlon of air conditioning apparatus, of which there ie much in the city, from time to time the attention of the public has been directed by ad­vertisements in the city newspapers to the waste of water by consumers, and such educational work will, it is hoped, produce lasting results. There is a olty ordinance relating to wasteful use of water, passed in July, 1939, but it has not been enforced. Last year, however, the city assigned a special uniformed officer during the heated term to look after the wasting of water by any and every means, and the LVLandVCo. paid one half of his salary. The results were very satisfactory. The LVL&ndWGo.fs water rates conform to a schedule fixed by the Public Service Commission of Merada and made effective on Sept. 1, -7 -
