A new system for locating leaks in urban water distribution pipes

摘要

Purpose - To introduce a new, low-cost and easy-to-use leak detection system to help water utilities improve their effectiveness in locating leaks. The paper also presents an overview of leakage management strategies including acoustic and other leak detection techniques. Design/methodology/approach - The design approach was based on the use personal computers as a platform and enhanced signal processing algorithms. This eliminated the need for a major component of the usual hardware of leak pinpointing correlators which reduced the system's cost; made it easy to use, and improved the effectiveness of locating leaks in all types of pipes. Findings - Effectiveness of the new leak detection system for pinpointing leaks was demonstrated using real world examples. The system has promising potential for all water utilities, including small and medium-sized ones and utilities in developing countries. Practical implications - The leak detection system presented in the paper will help all water utilities, including small and medium-sized ones and utilities in developing countries, to save water by dramatically improving their effectiveness in locating leaks in all types of pipes. Originality/value - The paper presents information about a new effective system for locating leaks in water distribution pipes. Effective leak detection tools are needed by water utilities worldwide.
