Chinese Capital’s Water Network Protected By Permalogs

Posted: Friday 18th July 2008

3500 Permalog loggers have been installed in the heart of Beijing to listen out for leaks in the mains water system. The HWM products are covering the area encompassed by the city’s 2nd Ring Road, which includes Olympic Games venues and Olympic Village facilities.

Beijing’s municipal water supply had its first 60 Permalog installations in 2000, and 2007 has seen over 3000 more loggers added. In addition to Olympic locations, Tiananmen, Zhongnanhai, Wangfujing and other key regions are within the monitoring zone. Already the system has helped to prevent any pipe bursts or flow problems during prestigious events such as the Sino-Africa Forum, Spring Festival, and the NPC and CPPCC sessions.

The use of the Permalog system has enabled the local water authorities to dramatically reduce leakage in the area, a strategy that is in line with national policies to aid water conservation. The drive-by feature also means that water companies can greatly reduce the time taken to investigate areas of the distribution network, and this has proved particularly effective in the busy metropolis of Beijing. Many of their water pipes are large, metallic systems that can suffer serious problems if any bursts occur. The Permalog network has enabled the engineers to pinpoint leaks quickly, so they can be fixed before developing into major incidents.

According to Allied Power (Beijing) Technology Ltd, HWM’s local distributor, the China National Science Commission and China Academy of Science have listed this project as one of the “Key Projects of 2007”. Mr. Wang Yaowen, Chief Engineer of Beijing Water Group said: “The Permalog water network leakage detection system is a leading system in the world. It has already been used in America and Europe for many years, and this project is helping to make Beijing’s water network as advanced as any other city in the world.”
