Abstract: Using reclaimed water perform groundwater recharge is a costeffective method to alleviated groundwater resource depletion problems caused by excessive extraction. The reclaimed water reuse status quo in China was described and the current international research development trends and progress about reclaimed water infiltration recharge were summarized. Combining our country actual situation, the authors point out that the research on reclaimed water reuse through groundwater recharge is an important new research direction in the field of surfacesoilgroundwater resources transformation, which has obvious characteristics of multiinterdisciplinary. Strengthen researches in this area have great practical significance for promoting safe reuse of reclaimed water in our country.
