The problems of water scarcity and urban waterlogging have a serious impact on people's lives and social development. The frequency of extreme weather events exacerbates this phenomenon. The new concept of sponge cities and Rainwater Harvesting Systems (RHS) came into the picture. Sponge cities and RHS are important for mitigating this phenomenon, especially in terms of rainwater utilization. This paper reviews the literature on sponge cities and RHS and analyses the position and effectiveness of both in solving the problem of waterlogging and improving the efficiency of water resources. The research found that both sponge cities and RHS can effectively improve the utilization of water resources. Sponge cities can decrease surface runoff and decrease the emerging risk of extreme weather. The purpose of this paper is to discuss the future development of sustainable drainage storage systems and to review past developments that can inform scholars of drainage storage in the context of sustainable development.
