Abstract: Domestic water consumption is currently the fastest growing sector in China's socio-economic water demand, and there is an urgent need for detailed and systematic analysis. To address this issue, a questionnaire was designed to collect relevant information on water use by Chinese residents, including dining, bathing, laundry, toilet flushing, household cleaning, as well as personal hygiene. The study analyzed factors influencing residents' domestic water use, and various water-saving scenarios were set to explore water-saving potential. The study found a 21% difference in per capita domestic water use among residents in different regions of China. Bathing, with an average water consumption of 38L/person·day, was identified as the primary water behavior causing this difference and a key area for future fine water monitoring and conservation efforts. Simulating scenarios to enhance residents' water-saving awareness, implementing water-saving measures, and replacing high-efficiency water appliances could save 32% of per capita domestic water use in China. It is recommended to continuously promote water-saving efforts according to the characteristics of domestic water use in different regions of China.
