The resource utilization of sewage after deep treatment has gradually become a real-istic choice for reducing carbon pollution and expanding green growth in our country.The key to the resource utilization of sewage is to determine the reuse object and the water quality target ac-cording to the demand.The current sewage resource utilization is still in the preliminary stage,the utilization level is low.Planning lacks resource allocation from the perspective of requirements.This paper takes a district of Suzhou city as an example to prepare the recycled water utilization plan.Focusing on the"demand side",the system planning is carried out from three aspects:utili-zation path,utilization and transportation mode,path and water intake point.Sewage resource uti-lization is used in four aspects:urban municipal water,industrial water,non-human contact envi-ronmental water,and district comprehensive utilization.In terms of engineering construction plan-ning,reclaimed water combines relevant local planning,spatial distribution of demand points and construction plans to plan near-and long-term supporting facilities.
