Leak Detecton: Two Methods That Work—Part II

This two‐part article is the second of several to be chosen for publication from over 30 papers presented at the first Distribution System Symposium (Feb. 24–27, 1980) in Los Angeles. OpFlow presents this and subsequent articles as examples of the high quality of material presented at the DSS. Part I presented last month (May) pointed out why the interest in leak detection has risen dramatically in the past few years, and noted that the approaches to the problem clustered around two basic methods of leak detection: (1) listening and (2) a combination of flow measurements and listening that is sometimes referred to as a “water audit.” The listening method, equipment, and procedure were discussed thoroughly in Part I. Part II of the article covers the audit method, and then gives advantages and disadvantages of both methods, and summarizes both Parts I and II.
