Price rate models are used for a variety of purposes including water conservation, what’s more, it is an effective and feasible method to establish a water-conserving society. The survey of household water consumption was conducted in a residential community in Hebei Province. An analysis of the survey data shows that an average family's water consumption is 6.4t per month, the standard is level 3. Three price rate models are proposed, the principle of the first model is the decrease of water consumption in level 1 and no increase in level 2, the second model is no change in level 1 and an increase in level 2, the third model is no increase for 80% of families and only 20% increased. After an analysis and comparison of water consumption and expenses corresponding to the three models, this paper presents these three models as a valuable reference for department decisions. The results of the first model should be adopted in Hebei Province, the demarcation point of every level is 8t and 13t, the price of every level is 3.04 RMB/t, 4.56 RMB/t and 9.06 RMB/t.
