Pipeline leakage is a difficult problem for most water companies, and it is also one of the important reasons for the high water supply and production gap. For the loopholes hidden in the underground pipe section, it has only been manually checked a little bit in the past, which requires a lot of time and manpower. Nowadays, Smart Water has given us a new way to achieve a good leak monitoring and control effect by simply modifying the pipe network and installing a high-precision smart water meter.
QuesTIon: How does Smart Water reduce leakage?
The Hewitz Smart Water Platform provides a solution called “DMA Partition Measurement and Leakage Analysisâ€. As the name implies, it analyzes the leakage through the sub-area water supply measurement. The specific implementation process is as follows:
Ø Water supply network level division: The water supply network is divided according to the actual situation. For example, one district in the city is set as a first-level area, and the residential concentration area (or street) is set as a secondary area, and the community is set to three levels. In the region, the entire city pipe network will be divided into several layers, and the water supply volume of each floor should theoretically be the sum of the water supply for the next layer.
Ø Add “smart water meterâ€: transform the water supply pipe network, and add a high-precision intelligent remote water meter with corresponding caliber in the general pipe section of each regional pipe network to collect the total water supply amount of the area and upload it to the data center.
Ø Analysis and investigation: Finally, through the Hewitz smart water management platform, online viewing and comparison of the data of each regional master table, you can understand the loss of tap water at all levels, and effectively screen out the pipe network area with more serious leakage. The manpower is arranged to be repaired in a targeted manner, avoiding the time and labor waste caused by blind leak detection and improving the efficiency of leakage control.
QuesTIon: Why do you have to "high-precision smart water meter"?
In fact, the scheme of “divisional measurement and leakage reduction†has been proposed very early, but it has not been implemented on a large scale in China for two reasons. First, the rules in the field of energy supply in China are still not perfect. There is no mandatory requirement for control, and the awareness of water saving for the whole people is not fully awakened. Second, the analysis of leakage requires the calculation of addition and subtraction of data from multiple tables. Therefore, the accuracy of the collected data is relatively high. In the past, mechanical instruments were mostly used. Can not meet the requirements.
For example, the water supply of all household water meters in a certain district is 14% less than the recorded data of the total meter of the community. It can be inferred that there may be a large leakage in the water supply pipeline of the residential area. However, in fact, all household water meters are mechanical water meters with a high initial flow rate. If the water flow is not counted at a small flow rate, then the 14% difference is meaningless because it is impossible to determine whether the deviation is caused by leakage or measurement error. The actual leakage may be only 5%.
Therefore, only by minimizing the error of the water meter can the partition metering achieve the desired effect. Today, Hewitz has ultrasonic electronic remote water meters in the large-caliber field, and Hamik's non-magnetic electronic remote water meters in the small-caliber field. All of them are high-precision water meters with a range-leading ratio in the market. The calculations provide reliable data and make the network loopholes nowhere.
QuesTIon: Why do we want to reduce leakage?
Ø National requirements: In 2015, the “Water Ten Articles†issued by the State Council required the basic leakage rate of the national public water supply network to reach the national secondary standard of 12% by 2017; to reach the national first-level standard by 2020. %. According to data from China Water Network, the average leakage rate of tap water companies across the country in 2014 is still as high as 15%.
Ø Water saving needs: 15% leakage rate means that for every 10 tons of water supplied, there will be 1.5 tons of loss. In other words, every 7 people will lose one person's water supply, and China's per capita Water resources will be higher than the world-recognized “water stress†line. If the leakage can be reduced to 5% or lower, it will be a milestone in water-saving actions, and China's water stress will also be greatly improved.
Based on the above situation, it can be said that reducing the leakage rate is everything: replace the Hammick non-magnetic water meter, build a smart water platform, and implement the district metering. These Hewitz can do it for you, so that you can easily reduce the leakage. Rate, meet national first-class standards, save more water!
