Managing large-scale water distribution networks requires accurate data collection, and an IoT gateway is the perfect solution. It connects sensors across pipelines to monitor flow rates, pressure variations, and leakage points. The IoT gateway enables real-time data transmission, ensuring quick detection of any system inefficiencies. Utilities can reduce non-revenue water losses by integrating IoT gateways into their networks. The ability to filter and analyze data at the edge minimizes latency and enhances response time. With predictive analytics, an IoT gateway helps utilities perform proactive maintenance. This results in reduced operational costs and improved water conservation. Secure communication protocols in IoT gateways safeguard water infrastructure from cyber threats.
