Managing large-scale water infrastructure, such as dams, reservoirs, and pipelines, requires advanced monitoring systems. An IoT gateway enables real-time data collection from multiple sensors, providing a unified view of water resources. It ensures stable connectivity, even in remote areas, using LPWAN and satellite communication. The IoT gateway helps in predictive maintenance by detecting anomalies in flow, pressure, and structural integrity. By integrating with AI-powered analytics, it enhances decision-making for water authorities. This technology improves efficiency, reduces operational costs, and ensures water sustainability in urban and rural regions.
