Abstract:

In order to reduce the level of pipeline leakage and ensure the safety and reliability of urban water supply, this paper took a typical water supply area in a city of Yunnan as a research object. Using set pair analysis of leakage prediction model (SPALF), the actual situation of the leakage of different pipe materials was analyzed from two aspects of the leakage quantities and the leakage rate of the water supply network, and the leakage trend of different pipe materials in the future was predicted as well, which could improve the level of active leak detection in water supply enterprises and the reliability of water supply safety, and reduce the leakage rate of pipe network and the cost of water supply.

Key words: water supply network, forecasting model, measures to reduce leakage, leakage rate, set pair analysis
