The rainwater harvesting system (RHS) is a facility installed in accordance with the ｢Act on promotion and support of water reuse｣ and is currently installed in various buildings such as apartment houses, business facilities, schools, and sports facilities. Rainwater is used for various needs, such as toilet flushing water, tree irrigation, road cleaning water, and landscaped facilities. In this study, rainwater utilization was calculated by performing a water demand-supply time series analysis through a hydrological water balance analysis. The water supply-supply time series water balance analysis was performed based on the recent ten-year period, and the water balance analysis for RHS analyzed the supply satisfaction, rainwater utilization, and rainwater coverage rates according to the demand scenarios of each facility. Through this method, it is expected to become a support tool for planning and operating the storage tank capacity of the target facility by confirming the rainwater utilization for various RHSs with different building uses and demand sources.

The global and regional systems for managing water resources are thought to be significantly impacted by climate change. Due to the fact that poor nations are most impacted, it has grown to be a significant worldwide problem. Natural disasters like aridity, droughts, floods, cyclones, and severe rainfall are all likely to have an impact on humans. Water scarcity can be brought on by climate change in some countries through persistent droughts. The rising population will result in a greater demand for water. Cities are becoming more vulnerable to water-related problems as a result of increased urbanization, changing rainfall patterns, and industrialization. The supply and demand of water can be balanced through the implementation of sustainable practices. In the event of future climate change, rainwater harvesting systems offer an alternative source of water and specific adaptation strategies for coping with water scarcity. The adoption of rainwater harvesting systems is discussed in this article as a strategy for climate change.

Urban stormwater is known to cause a myriad of problems, ranging from flooding to water quality degradations. This paper provides an extensive review of analytical probabilistic model (APMs) used in the design of urban runoff control systems. APMs are closed-form mathematical expressions representing a long-term system’s output performance derived from the probability distribution of the system’s input variables. Once derived, the APMs are easy to handle, allow for sensitive analysis, and can be co-opted into optimization frameworks. The implementation of APM in the planning and design of runoff control systems will not only help address the runoff quantity and quality problems of urban stormwater, but will also go a long way in optimizing the benefits derived from the systems. This paper reviews studies that document the negative impacts of urbanization on runoff quantity and quality, and the best management practices (BMPs) used to mitigate the impacts. Three design methodologies used in urban stormwater control systems were reviewed. A detailed review of research on the development and use of APMs in urban stormwater management in various runoff control systems is presented, and recommendations are proffered.
