Abstract In order to improve the capacity of water supply in mountain areas and remote areas in China, the development process of the equipment in the "water carrying" was discussed. The current water supply system and the main working principles of emergency equipment were introduced. The development status of specific rescue equipment such as feed pump, vehicle system and secondary pre-ssure pump station was presented. The emergency water lifting equipment involves many pump products. The performance gap is gradually narrowed with foreign countries. Although the products have high-cost performance and various models for choice, the quality and reliability need to be improved due to the limited range of processing and manufacturing accuracy and material selection. Vehicle platform constantly improve the fatigue strength, reliability, and lightweight frame. However, it is limited by various parts with complex layout. It is also lack of the whole machine optimization. The mounting system has changed from a single objective optimization to multi-objective optimization based on computer calculation, which has greatly improved the riding experience and the vibration of the carriage. Pipeline water hammer and pipeline leak monitoring rely on the more robust algorithm and higher precision. What′s more, digital twin is the trend of emergency water pipe network control, relying on the Internet of things, 5 g, big data and cloud computing, etc. From basic data to digital simulation, and then to scheduling command and decision support, it will realize change of the automation, informatization and the digital to the wisdom which will greatly improve the efficiency of emergency rescue.
