This paper considers the water supply, sewage treatment and the affordability of urban water users, the nonlinear water price model for urban water user is established, in which the objective function is maximum the total social surplus. The Lagrange multiplier method is used to solve the model. The relationship between the ratio of the local water supply and the water price of urban water users is discussed. At last, the numerical example of a city is given.
