In recent years, rain barrels (RBs) have emerged as effective stormwater management tools for mitigating urban flooding. Our previous study in Saitama City revealed that traditional RBs performed poorly the densely populated residential areas compared to other low-impact development solutions. This investigated effectiveness of smart RB, comprising water pumps. These SRBs can be controlled online using switches rely on local weather forecasts, ensure are emptied before rainfall. We aimed assess how reduce pluvial flooding during continuous rainfall PySWMM model. varied drainage values simulations control activation switches, enabling us evaluate flood reduction. The results showed reduced total runoff volume by 2–10% RBs. Moreover, although reduction effect was found independent their size, increased proportionally with capacity.
