Reclaimed water is the second water source of city and can effectively alleviate the water crisis. Taking that the funds of reclaimed water network construction should be recovered as the premise,the paper used the method of cost-plus to determine the functional relation between cost price, demand and transportation distance of reclaimed water used by users. The users are divided into different groups according to the distance between users and water plant.According to the demand diversity in different users, it took to price reclaimed water and set up a complex tiered pricing method based on water requirement of reclaimed water and the distance of conveyance. Finally, taking the second sewage treatment plant in Xi'an for example,the paper used model to calculate the water price of user - western suburbs power plant of Xi'an,and verified the accuracy and usefulness of pricing model. The result can provide a theoretical basis for the development of market of recycled water price.
