The underground pipelines in the city are densely packed. When problems arise, they can be repaired manually. As a result, the city frequently encountered dangers such as water bursts or gas leaks. It is estimated that if the average leakage rate is calculated at 20%, China's water companies will have 10.2 billion tons of leakage water a year. 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, then the economic loss of leakage water loss will be as high as 20 billion yuan. I am afraid that such a huge loss should allow water companies to reflect on it. Can you know in advance what went wrong and rule out the danger before it broke?
In this information age, with the rapid development of economy, the Internet has entered millions of households, and the information age has also made people's lives more convenient. The Internet has spread across various industries and plays a significant role in urban water management. With the help of the network and cloud computing, Smart Water Services has realized functions such as real-time monitoring, water supply trend forecasting, emergency warning and emergency handling, effectively improving the intelligent management of urban water supply.
In the world, there have been two famous cases that fully demonstrated the prospects and trends of smart water services.
The first example is Qatar Pipeline Leakage Management. In Qatar, the leakage rate of the water pipe network was 59.1%. In order to meet the needs of major international events, Qatar urgently needs to reduce the rate of production and sales, save water resources, and increase water supply profitability. After four years of using smart water to control leaks, Qatar's pipe network lost half of its lost water, saving 14 million euros annually. The country’s water company also became the most efficient water company in the Gulf region.
Another example is the British Anglian network leakage management. By analyzing the problems in the construction and maintenance of water networks, Smart Water Solutions helped the UK's largest water company reduce 5% leakage, and since its operation, it has solved about 27,000 leakage points each year, reaching the lowest level of leakage rate in the UK. Improve operational efficiency.
For information technology experts, monitoring the pipeline is not a particularly difficult task. A central computer server and several sensors are all available. Researchers have used information technology to develop an intelligent urban water supply monitoring system that can effectively reduce the leakage or breakage of water pipes. The smart system's monitoring center has a central server and a number of computers to monitor the city's information from all water pipelines around the clock. This information comes from several sensors, smart meters and smart valves in the water pipe network.
For example, if a water pipe leaks from a public pipe in a city, it will not be discovered by residents or maintenance workers if the crack is small, does not wet the floor, or is ejected. If you do not repair this small gap, it will inevitably lead to long-term leakage, resulting in the waste of water resources. What is more noteworthy is that small cracks do not undergo maintenance, and may gradually become larger. They may even result in the complete rupture of the water pipes, resulting in the collapse of roads, the suspension of water in residential areas and the collapse of underground pipeline tunnels. If there is a smart water supply system, the sensor can detect a small gap in time, transmit the information to the command center and send an alarm message. The command center can send the location of the pipeline with a small gap to the maintenance center, and the maintenance center can promptly clear the hidden dangers.
If the water pipes in the house are broken and not repaired in time, not only will the decoration of the home be damaged, but the neighbors downstairs may also be affected. For residents' homes, the pipeline is generally not equipped with sensors. At this point, smart water meters and smart valves come in handy. Intelligent water meters and smart valves can record residents' water usage and water consumption. If the smart water meter monitors that the residents' water is suddenly over-absorbed, or if the water is over-used during a period of less-than-used water, the smart meter transmits information to the command center, and the command center contacts the residents again if the water consumption does occur. If there is a difference between the monitoring information of the water meter and the water consumption of the residents, the information will be sent to the maintenance center. The maintenance center will send people to serve the residents.
Smart water systems can also be used to regulate water pressure. For the general urban water supply system, most of them use a hydraulic pressure to supply water, which results in an excessive amount of water in the idle state and a small amount of water in the busy hour. Excessive water volume leads to the waste of water resources, and water volume is too small to facilitate residents' lives. The intelligent water supply system can use sensors to dynamically monitor the flow of water. When the flow is large, it indicates that there are more people using water, and the system will automatically increase the water pressure; if the flow rate is small, there will be less water, and the system will automatically reduce the water pressure. Adjusting the water pressure according to the flow rate can not only prolong the life of the public pipeline, but also prolong the life of residential household pipelines, water meters and valves.
From the perspective of the development of new technologies, it should be said that smart water has become the direction of water management. However, despite the promising prospects for the construction of smart water, there are still many concrete obstacles to its development. For example, some Chinese water companies have unclear understanding of the concept of smart water services. Some companies always want to do it in the process of investing in smart water, and others still wait and see. At the same time, how some public data resources are opened and shared in an orderly manner and coordination between regulatory agencies needs further study. But in any case, the development of smart water services has been waiting for.
Tap water leaks 20 billion yuan a year in urgent need of intelligent water meters
[China Instrument Network Industry Focus] According to relevant data, China's water companies' annual loss of tap water can reach 20 billion yuan. How can we respond to this? In recent years, a new smart water technology has emerged as the times require. The smart water service has realized functions such as real-time monitoring, water supply trend forecasting, emergency warning and emergency handling through the help of network and cloud computing, effectively improving the city’s water supply intelligence. The management level has become the direction of water management.
