[China Instrument Network News] One of the essential resources for human survival. With the gradual lack of water resources, protecting water resources has become an important task. With the development of technology, the water supply system also makes use of cloud computing and big data analysis technologies to perform meticulous monitoring and systematic management of the district pipeline network, which promotes the development of smart water services.
China has 20% of the world’s population, but only 7% of the world’s freshwater resources. The serious scarcity and shortage of water resources have become an imminent environmental crisis. However, every day under our city, the root-and-spoke water distribution network is losing our valuable water resources with an average leakage rate of 20%.
According to the statistics of E20 Research Institute, the current construction speed of China's water supply pipe network is 30,000 kilometers per year, and the average leakage rate of urban public water supply pipe network in China is 20%, while that of China's water supply enterprises is about 10.2 billion yuan a year. Ton, what is this concept? This is equivalent to the total annual water diversion of the Middle Route Project of the South-to-North Water Diversion Project, with 150 million urban residents drinking water for a year and nearly 10 Miyun Reservoir. If the cost of water supply per ton of water is calculated at 1.5 yuan, the direct economic loss caused by leakage losses will be 15.4 billion yuan each year. If the price of water sold per ton of water is 2 yuan, the economic loss of leakage water will be as high as 20 billion yuan.
The long-term leakage of the pipeline network will not only cause waste of water resources, but if it is not repaired in time, the gap will gradually become larger, which will result in the complete rupture of the pipeline, resulting in the collapse of the road surface, the suspension of water in residential areas and the collapse of underground pipeline tunnels. At the same time, when the water supply pressure changes, the negative pressure formed around the leakage point of the pipeline will inhale the external pollutants into the water supply network system, posing a safety threat to the residents' drinking water.
So, is there any way to achieve effective leakage prevention? In fact, at present, many countries in the world have already implemented advanced management concepts and methods such as zone management and refined pressure management, and have kept the leakage rate at a relatively low level for a long time. Taking the Anglian network leakage management in the UK as an example, through the analysis of water network construction and maintenance issues, Smart Water Solutions helped the UK’s largest water company reduce 5% leakage, and since the operation, it has solved about 27,000 leakage points every year. It has reached the lowest level of leakage rate in the UK and has greatly improved operational efficiency.
In China, Anheng Group and its water network technical service center has been committed to the research and engineering practice of water-supply pipe network leakage control, independently developed Leakview® pipe network leakage control system based on the concept of “water-network®†and its The active leakage control solution of the DMA partition has become the only highly reliable, high-performance, highly-efficient and informatized solution for monitoring and leakage control in the water supply industry, and has become an important component of smart water management. This set of solutions mainly includes three major leakage control technologies: DMA partition measurement, leakage noise on-line monitoring, and intelligent refinement of regional pressure control. Relying on LeakView® system, a leakage management cloud platform independently developed by the Waterline Technology Service Center, it is intuitive and effective. The three major leakage control techniques will be integrated. DMA partition metering refers to the establishment of a minimum leakage assessment particle, which divides the overall system into smaller subsystems and separately calculates the leakage loss of each subsystem to improve the ability of leakage management. Leakage noise on-line monitoring is to upgrade the traditional manual leak detection tool to a leakage noise sensor. On the basis of the DMA partition, real-time segmented monitoring is performed to accurately predict the position of the leakage of the pipeline network. Intelligent fine area pressure control refers to the use of hydraulic pressure relief valve to achieve automatic control of regional decompression, through two-point decompression (hold pressure) and continuous decompression (hold pressure), etc., at the peak of water use and In the low-peak area, the corresponding pressure value is switched, or the real-time continuous pressure control is performed according to the actual water demand of the client, so that the fine pressure control can be achieved, so that a rapid and significant water-saving effect is achieved, and the risk of tube bursting is effectively reduced. All monitoring data will be uploaded to the LeakView® control and analysis system in the cloud. Cloud computing and big data analysis technology will be used to finely monitor and systematically manage the district pipeline network.
It is reported that Leakview® leakage control system for water network technology service centers and active leakage control solutions based on DMA partitions have been implemented or applied by terminal water control and demonstration facilities in about 20 water utilities throughout the country, including the Beijing Water Group. At the same time, dozens of water supply network pressure control areas are also established throughout the country. The total annual water saving is about 2.16 million cubic meters. Among them, the project implemented in the Yongle Community in Shijingshan, Beijing, starting from October 2011 not only reduced the rupture of the pipe network and the bursting rate of the community to zero, but also achieved a daily saving of nearly 1,000 cubic meters. It is expected that the annual water saving of the community will be realized. Will exceed 300,000 tons. Residents of the community said that not only are they concerned about the amount of water they are worried about since they managed the LeakView@ (Leakage Visualization) pipe network leakage management platform and the DMA-based urban water supply pipe network integrated leakage control program to manage the community pipe network. There was no reduction in the situation where the high-level water pressure did not increase. Instead, the amount of water used was sufficient. In addition, the water quality turned yellow and the construction of digging trenches everywhere in the community was also solved. The project also saved a lot of manpower and material resources for the Shijingshan Water Company, and achieved an intelligent and preventable leak-preventing pipe network.
As an intelligent water informatization expert of Anheng Group, the Water Networking Technology Service Center always adheres to the integration of cutting-edge technology and information technology into the development of water and environmental protection industries, and carries the essence of the Water Network®-Internet+ intelligentized fine water management system theory. The leading lean research and development capabilities and the strength of always keeping up with the international information technology, combined with the intensive cultivation of the Group's water and environmental protection field for more than a decade, focusing on urban water supply, pipe network leakage control, efficient use of water resources, and municipal energy conservation and innovative technologies The actual engineering application has become a quality service provider in the water and environmental protection industry with continuous advancement of technology research and development capabilities, leading solutions and excellent project implementation levels. Group CEO Wan Zhonghua stated that with the process of urbanization in China, the issue of carrying capacity of water resources and water environment is getting more and more attention. To practice Xi’s instructions of “saving water firstâ€, the development of water resources inventory assets will become current and future. One of the most important industry tasks is that the Leakview® Leakage Control System for Leakage® Leakage Control System and Active Leakage Control Solution based on DMA Partition developed by the Waterline Technical Service Center based on the concept of “Water Network®†is intended to be innovative and practical. The plan will solve the bottleneck problem of water resources in the process of urbanization, save water resources, and support the sustainable and healthy development of the city. The RMB 20 billion pipeline leakage reminds us that the smart water market has a vast space. The future water market will belong to smart water, and the early spring of smart water service has arrived!
