Comparison of Water Consumption in 2022 and 2023.

With China’s rapid urbanization, water scarcity has emerged as a critical issue affecting living standards and urban sustainability. Urban water-using units, as major consumers, play a pivotal role in national water-saving efforts, yet face challenges such as low water-saving awareness, high leakage rates, and limited intelligent management. This study aims to design and apply an intelligent water-saving system to improve water-saving management in urban water-using units, using schools and hospitals as case studies. The system integrates GIS, IoT, big data, and AI to enable real-time monitoring, data analysis, and visualization of water usage. It provides a comprehensive evaluation of water-saving effectiveness, addressing past management challenges and enhancing efficiency. The intelligent system supports visual, intelligent, and scientific water-saving management, offering essential data and functional tools for urban water-using units. Future efforts should focus on further utilizing big data and artificial intelligence algorithms to simulate and identify water use characteristics, so as to assess the unreasonable water usage more scientifically and provide more effective support for water conservation work.
