As an optimal management system for the stable supply of water facilities, it collects measurement data (flow rate, pressure, water quality analysis) and analyzes the water flow rate/leakage rate of the water supply network. thereby controlling the pump and valve to control the water supply of the water supply network. And based on this, it is a system for optimal management of water supply network that can support operator decision-making (water supply quantity and usage by use and season) and increase the convenience of maintenance work (pipe network maintenance, maintenance).
