1. What should be done if there is a leakage in the urban water supply network, and how to ensure the smooth operation of the water supply network? Leakage in the urban water supply network needs to be solved through monitoring and early warning, scientific maintenance, and system management. To ensure smooth operation, real-time monitoring, data analysis, and intelligent regulation need to be combined.

One of the main causes of leakage in urban water supply networks. Leakage in water supply networks is a common problem in urban water supply systems, and its causes are complex and diverse, mainly including the following aspects: pipeline aging: water supply networks are buried underground for a long time, and pipeline materials (such as cast iron pipes and steel pipes) may cause interface loosening, pipe wall rupture, and other problems due to corrosion and aging.

. For example, the risk of pipeline leakage has significantly increased after more than 30 years of use. Geological factors: Uneven soil hardness, changes in groundwater level, or ground subsidence can cause uneven stress on pipelines, leading to deformation or rupture. Temperature changes: Seasonal temperature differences can cause loose expansion joints in pipelines, and low temperatures in winter may even lead to pipeline freezing and cracking. Load pressure: The pipeline is laid under the road and can withstand vehicle dynamic loads or building static loads for a long time, making it prone to rupture due to excessive local pressure.

2. Solutions for Water Supply Network Leakage: To address the issue of leakage, a combination of "prevention+repair" strategies should be adopted, with core measures including the application and scientific

maintenance of water supply network monitoring systems.

. 1. Deploy a water supply network monitoring system. The water supply network monitoring system uses the Internet of Things, sensors, and data analysis technology to achieve real-time perception and risk warning of the network status, and is a key tool for controlling leaks. Real time monitoring function: The system monitors parameters such as pipeline pressure, flow rate, and water quality 24 hours a day through devices such as pressure sensors, flow meters, and leak detectors. For example, sudden pressure changes may indicate the risk of pipe bursting, while abnormal flow rates may indicate leakage points. Data analysis and warning: Based on historical data and machine learning algorithms, the system can identify leakage patterns, predict risk areas, and push warning information through SMS, APP, and other methods to help management personnel quickly locate problems. Intelligent regulation of water supply parameters: Based on real-time data, the system can automatically adjust the pressure and valve opening of the Mazhou pump station to avoid pipeline rupture caused by high pressure, optimize water supply efficiency, and reduce energy consumption. 2. Regular maintenance and updating of aging pipelines. Pipeline inspection: Combined with monitoring system data, manual inspections are carried out in high-risk areas (such as old residential areas and geologically unstable areas), with a focus on checking the corrosion of interfaces and pipe walls. Phased pipeline replacement: Develop a replacement plan for pipelines with a service life exceeding 20 years, prioritizing the replacement of pipes in areas with frequent leaks (such as using corrosion-resistant ductile
