Show Hydro Plant Won't Contaminate Water, Says Board of Health Hon. Mayor and City Commissioners, St. George, Utah. Gentlemen: Regarding installation of a hydroelectric hydro-electric power plant at some point in the St. George municipal water system, it is our opinion that such installation would not constitute a health hazard providing the supply is delivered to the plant in a closed conduit and conducted from the plant back to the system in a closed conduit. Merely running water through the Pelton wheel of a power plant would not serve to contaminate the supply. It is felt that such an installation instal-lation would be comparable to the flow of water through a water meter, such as you have on each house conneetion, and which we know does not contaminate the supply. A possible source of contamination in connection with such a proposal would occur during installation and at times when repairs to the wheel are necessary, but it is felt that such possibilities can be overcome with little difficulty providing provid-ing your waterworks superintendent is given full authority to supervise thorough disinfection of the wheel mechanism and channel following installation and subsequent subse-quent repairs. Such disinfection can foe accomplished in a manner similar to that now employed in the disinfection of your concrete reservoirs which will result in no change of water quality resulting from the disinfection methods. Very truly yours, UTAH STATE BOARD OF HEALTH, Lynn M. Thatcher, Director Division of Public Health, Engineering En-gineering and Sanitation. |
