In Singapore, advanced smart drainage systems automatically activate during heavy rainfall to prevent urban flooding. Sensors monitor water levels in real time, and when thresholds are exceeded, automated gates and drainage channels open to redirect excess water. This proactive system reduces flash flooding in dense urban environments, protecting infrastructure, businesses, and residential areas. Singapore’s drainage network is integrated with predictive weather modeling, allowing authorities to
