Water source is crucial to the formation and development of life. As early as thousands of years ago, human beings in primitive societies lived by water. Now, water resources are an indispensable material condition for the formation and development of cities. In order to facilitate human beings to obtain water, special water supply systems have been built in modern cities. In recent years, with the gradual acceleration of urbanization, people's requirements for the quality of urban facilities are also constantly increasing. However, at present, in the water supply systems of most cities in our country, light or heavy water supply pipe network leakage can be basically found.
Urban water supply systems usually consist of water sources, water pipelines, water plants, and water distribution pipe networks. After water is taken from the water source, it is sent to the water plant through the water pipeline for water quality treatment, and then sent to the user through the water distribution pipe network. As the lifeline of the urban water supply system, if the water supply pipe network leaks, it will cause problems in the entire city's water supply system. In actual situations, there are many reasons that cause leakage in water supply pipe networks. For example, water pipes are aging due to their age, water supply pipes are made of poor materials and have low strength, pipeline corrosion and inadequate construction are all possible causes of water pipe leakage. occur.
At this stage, the leakage rate of urban water supply pipe networks in my country is generally high. According to a survey, the leakage rate of tap water pipe networks in 26 provinces and cities across the country is as high as 15%, and 13 of them even exceed 20%. However, due to aging pipeline materials, backward supervision systems and technical means, these leaks cannot be monitored and processed in a timely manner, and the traditional water supply supervision system cannot meet the requirements for real-time monitoring, data processing and control of leaks in the water supply pipeline network. . This not only greatly increases the operating costs of the water supply company, but also wastes a large amount of water resources. Therefore, water supply pipeline leakage has become a major problem restricting water supply enterprises and urban development.
According to the China Science News, Zhu Junwu’s team from the School of Information Engineering of Yangzhou University recently developed an “urban water network leakage monitoring system” and has been officially put into trial. It is understood that the system can monitor and record various information on the city's water supply pipe network through dedicated water metering devices, and transmit data such as water flow and pipe network pressure in real time. After detecting leakage, it can promptly report the leakage to the supervision platform. Alarm reminders can effectively reduce the leakage rate in urban water supply.
According to relevant personnel, this system can reduce the leakage rate of urban water networks to 8%-12%. If promoted nationwide, it is expected to reduce the amount of water leakage by 7 billion tons. , economic losses of more than 14 billion yuan, effectively solving problems such as water pipe network leakage rate and low urban water supply efficiency, which is of great significance to the development of cities in northern my country that are short of water resources and have serious water network leakage. At present, this "water network leakage monitoring system" has been installed in Tongliao City in Inner Mongolia, Qinhuangdao City in Hebei Province, and Mengcheng City in Anhui Province.It has been put into trial operation in other places and has achieved good results. It is expected to further expand the scale in the market and gradually realize industrial development.
In daily life, as long as we twist the water, water will come out continuously. Therefore, most people may not feel the preciousness of water resources, and of course they do not know how much water will be lost in the urban water supply network during this process. However, water resources are not inexhaustible. Inexhaustible. Saving water resources not only requires the use of science and technology, but also requires us to start from the "bits and pieces" of our lives.
Editor’s comment: Freshwater resources are very precious. Our production and life are inseparable from this rare resource. Pipe leakage will cause us to lose a large part of our freshwater resources, which is harmful to the environment. It is a big pressure for human development. Nowadays, relying on superb science and technology, we have developed relevant monitoring systems that can effectively avoid and solve pipeline leaks. We believe that the use of this technology can successfully help people save resources.
