uWater
Water supply network integrated operation management software
uWater is Water supply network simulation software. It has DDA (Demand Driven Analysis) and PDA (Pressure Driven Analysis) analysis functions for water supply network simulation, as well as A-PDA (Advanced-PDA) algorithm was applied which can simulate hydraulic behavior in abnormal water pipe network situations such as water outages and pipe breaks.
Various Mathematical Analysis Functions
uWater is the first to apply DDA, PDA, and advanced Advanced-PDA algorithms for simulating water supply networks.

Water Distribution Network Simulation under Abnormalities
uWater's A-PDA algorithm enables effective simulation of various emergency situations that may cause water supply restrictions in real pipe network systems.
- Reservoir Failure: Implementation of water system conversion in case of emergency, calculation of available service time and amount of reservoir supply, etc.
- Singleness Pipe Failure: Calculation of flow rate and pressure change due to single pipe failure
- Isolation segment: estimating the extent of damage and supply of the isolated area
Water Quality Analysis of Water Distribution Network
uWaterapplies Multi-Species Extension (MSX), which enables modeling of highly complex reactions between a variety of chemical and biological species, both in the flow and on the wall of a pipe in the water supply network. This allows you to analyze the behavior of water quality in the water supply network over time.
- Simulation of non-reactive tracer substance movement
- Analysis of the movement and reaction of reactants that increase (disinfection by-products) or decrease (residual chlorine) over time
- Calculation of the transit time of water in the water supply network
- Calculation of the ratio of water from each intake source when mixing in a pipe network in multiple intake sources setting
- Analysis of coagulant components as well as individual compounds or ionic reactions such as HOCl and OCl-
- Compounds that can adsorb or desorb on the surface of the pipe, such as particulate matter and organic matter, iron oxide, etc. adhering to the surface of the pipe wall
Water Distribution Network Adversarial Analysis
uWater analyzes conduits with a high probability of occurrence of red water due to changes in water flow direction during water system conversion or in case of emergency in the water supply network.
- Comparative analysis of the analysis result of the general condition and the flow direction change result due to opening and closing of the conduit or valve
- Analyze the list of conduits where the flow occurred at zero or the flow of water was changed
