A utility network refers to a system that manages the distribution and supply of essential services such as water, electricity, gas, and telecommunications. An example of a utility network is the water supply system in a city, which includes a wide range of components such as reservoirs, pump stations, pipelines, and treatment plants. This network ensures that clean, potable water is delivered from the source to households and businesses, while also incorporating mechanisms for monitoring usage, detecting leaks, and managing pressure. By utilizing advanced technologies like smart meters and geographic information systems (GIS), utility networks can enhance efficiency, reduce waste, and ensure reliable service for the community.
