Integrated Leak Detection at Dallas Water Utilities

Abstract

Dallas Water Utilities employs an innovative leak detection program which utilizes a variety of technologies to detect, locate, and repair leaks in both their water distribution and transmission systems. Over the past twelve months, this program has located over 200 leaks in Dallas' water distribution system, for an annual savings estimated at 100 million gallons of water. Over the past 2 years, Dallas has expanded their leak detection program to include the use of the Sahara T M leak location system on their large diameter transmission mains. This paper discusses the technology and methodology used in Dallas' leak detection program, outlining the results achieved, and plans for further use of this program. Specific cases will be discussed in detail, with a focus on the innovative use of new technology.
