Practical Research on Leakage Control of Public Water Supply in a County in Northern China

Abstract

Aiming at the prominent problems of the public water supply system in a county in northern China, such as unclear pipe network assets, low informatization level and inadequate leakage control measures, a comprehensive leakage control solution for water supply pipe networks was designed based on new-generation information technologies including GIS and IoT. The solution integrates pipe network census, district metering management, information software system development and management mechanism construction. Through the implementation of this solution, digital management of water supply pipe network assets, real-time perception of operational data and intelligent early warning were achieved. The leakage rate of the pipe network in the research area was stably controlled below 9%, which significantly improved the refined operation and intelligent management capacity of the local water supply enterprise. This research provides a referable technical path and practical paradigm for water supply leakage governance in similar small and medium-sized towns in China.
