Control measures to reduce leakage rate
When controlling the leakage of the water supply pipe network, scientific management measures such as metering management, pipe network management, and water use management can be used to effectively reduce the leakage rate of the pipe network.
1. Adopt DMA partition metering water supply management technology. By partitioning the urban water supply pipe network, real-time monitoring of the flow of the water supply pipe network in each district is carried out. In this way, pressure management, statistics and flow analysis are carried out for each zone, and then the leakage level of each zone and the approximate scope of water leakage can be quickly and accurately quantified, and finally the water leakage site can be accurately located, and the water leakage point can be repaired, so as to reduce the amount of water leakage and control the leakage.
For example, its water supply pipe network leakage monitoring system can detect the abnormal water supply in the pipe network in time by monitoring the flow and pressure nodes in each DMA (independent metering area) in real time. Finding leakage points provides scientific guidance for the reduction of leakage and assessment of leakage in the water supply system, and provides the most convenient and practical analysis platform for water supply enterprises to reduce leakage and analyze leakage.
2. Strengthen the use of water supply pipe network fault monitoring technology and equipment, and increase the high-tech content in water supply pipe network leakage control. By installing sensors on the "nodes" of the water supply network, obtain online real-time hydraulic data, upload the hydraulic data to the cloud database and analyze it, determine the real-time situation of the water supply pipeline, and predict the possible subsequent leakage points and pipe burst positions, etc., so as to supply water. The department shall deal with it in a timely manner, thereby reducing the leakage rate of the water supply network.
3. Strengthen water management. In the daily leak prevention work, actively connect with enterprises with high water consumption such as steel, petrochemical, energy, automobile manufacturing, etc., establish an active prevention and control mechanism, combine passive repair with active prevention and control, and establish a perfect mechanism for leak prevention and leak detection; improve A water metering system is established for municipal public industries, such as fire hydrants, etc., and metering water meters are installed to reasonably measure water for firefighting and sanitation; cooperate with law enforcement agencies to strictly control water theft and improve the water supply inspection system.
In short, the leakage control of water supply network is a complex project. In the process of improving the operation of the water supply network, attention should be paid to the application of leakage control measures in the water supply network to ensure that the leakage rate of the water supply network is effectively reduced.
