Reducing Water Pipe Network Leakage Changzhou, Jiangsu R&D “Learning Leak” Sensor

[China Instrument Network Instrument Research and Development] With the continuous economic and social development in China and the accelerating process of urbanization, the construction of water supply pipe network and other supporting facilities has also achieved unprecedented development. According to relevant data, the current penetration rate of urban water supply in China has exceeded 95%, and water supply capacity and water consumption have increased by 4.6 times and 3 times respectively compared with 20 years ago.

However, while the coverage of the water supply network is widening and the capacity for water supply is increasing, the water supply pipe network in cities in China also suffers from problems such as high leakage frequency of the pipe network. It is estimated that the average leakage rate of the pipe network of the public water supply system in our country reaches 21.5%. Therefore, how to reduce the leakage rate of urban water supply pipe network and reduce the waste of water resources has become a top priority in water supply.

However, most of the water supply networks are underground, and it is difficult to find leaks. However, traditional leak detection methods often require manual inspection of “listening leakage” along the line during the dead of night, and the timeliness of leak detection is poor. The experience of “leak leakage” personnel depends on a large degree, and the accuracy of leakage point measurement is also relatively poor.

In order to discover the leakage point of the water supply network in time and improve the timeliness of leak detection and the accuracy of leakage points, an enterprise in Longzheng Intelligent Sensor Town, Changzhou, Jiangsu Province, successfully developed a “listening leak” sensor that can be “listened” at the furthest distance. "300 meters, and good performance in the trial operation of several colleges and universities.

According to briefings, the “artifact” of the leak needs to install a noise sensor on the pipeline every 200 meters or so. Generally, it can be installed using the inspection well or valve well of the underground pipe network. After detecting the missing point information, it can not only be transmitted to the computer client of the monitoring system, but also can be directly transmitted to the mobile phone terminal for convenient and timely processing, and the cost is only one third of the UK imported equipment, each about 8,000 yuan.

Controlling water supply leakage is one of the important signs for creating a water-saving city. Reducing the leakage rate of water supply network is an effective way to save water resources. With the development of creating water-saving cities, the water supply department has continuously increased its efforts to update and overhaul the “overtime” pipeline network, and adopts high-tech leak detection methods to continuously improve the scientific and technological content of water supply pipe network management. Leakage sensors will be used in more and more water supply departments.
