Abstract:On the basis of material balance approach, the water balance models for the economic system and three sectors were constructed separately. Taking A City as a case, the amounts of water use and sewage emissions were computed ,by using the water balance model, and the implementation effects of the water price policies were assessed, which wasto provide a reference for formulation, implementation and improvement of the water price policies. The results demonstrated that water recycling had dual effects of water conservation and pollution abatement. The ratio of water consumption and discharge and the amount of untreated waste water in industry were much higher than that of residents, which were 2.9 and 3.6 times in A City respectively. Poor management of water use and waste water could lead to the revenues of water pricing much lower than the proposed ones. In A City 118.02 million RMB were uncollected with the standard of water price in 2009. In conclusion, effective water pricing policies should be established on the basis of strict supervision.
