“…This may be accomplished with sonic leak detection methods, which enhance the natural hearing of a listener, or acoustic leak detection techniques, which are electronic in nature 5 . These two methods are the most commonly used among municipalities of all sizes across North America, and there is evidence that a vigorous program of leak detection and repair can significantly reduce the amount of unaccounted‐for water in a distribution system 1 , 4 , 6 – 8…”

“…For example, in Gary, Indiana, a steel distribution system leaked due to temperature variation (0 ° to 22°C). Several hundred leaks were detected and repaired, saving millions of gallons of water annually (Pilzer 1981). A more unusual case occurred in Honolulu where "... ground termites were boring through rubber gaskets at the joints of the 200ram water lines ..." (Hayashida 1984).…”
