Abstract: With the development of mega cities, the scale of population continues to expand, hence the problem of water shortage is getting more and more important. In this paper, the analysis of water use in Beijing city is analyzed, the status of high efficiency water use is diagnosed, the efficiency of urban household water use is comparatively analyzed, and the regulating model of high efficient water use on Beijing city is proposed. The results show that Beijing city is facing the rapid increasing in the total amount of water, water use structure is gradually rigid. Due to the higher water efficiency in Beijing city, the structural water saving potential is gradually reduced, the management of urban household water use turns out to be the focus of water-saving. The water habit of residents is the important factors that affect the urban household water use. Finally, water regulation models are proposed, including the strict control of population growth, the reduction of the threshold of the price ladder, the encouragement of consumer to undertake the water price of public service industry, and the development of water use management mechanism on the red line of industry efficiency
