About EPANet

Water distribution modeling software developed by the US, ie the Environmental Protection Agency (EPA), water supply and water management. EPANET performs a prolonged simulation of the hydraulic quality simulation within the pressure piping network and is designed as a “research tool” to improve our understanding of the flow of drinking water in distribution systems. The first EPANET appeared in 1993.

EPANet Simulation

After setting all the initial parameters, a simulation is based on a predefined and calibrated model of the water supply network.
The simulation results are the data of the network state at all points of the simulated model for a given time period  that are placed in the specific table of results.
The results obtained are further processed to detect possible water loss in the water supply system.

Example of Executing EPAnet Simulation Code:

The simulation result processing is performed by a special algorithm according to which the simulated values are gradually approaching real, readable measurements from the SCADA system.

All processing results are entered into the database for further processing and presentation in the EPA Scada. The data used for further processing are:
  • pressure (measurement unit: bar) in nodes (read and simulated value, calculated error of these two values, calculated error of these two values)
  • water flow (measurement unit: l / s) in pipes (read and simulated values)
  • water level (measurement unit: m) in all water retention in the network (read and simulated value, calculated error of these two values)
  • valve status, pumps and pipes.
