WATSYS or WaterMax

WATSYS / WaterMax is an engineering software package that is used to simulate the real time behaviour of large water supply distribution networks.  Both hydraulic and water quality behaviour can be simulated.

Units

Simulation may be carried out using either metric or imperial units with pipe flows determined either by the Colebrook-White or Hazen-Williams formulae.  In addition the user may choose the units to be used for flow.

Time

Simulations commence with a network balance at the specified starting time.  After this starting point the time is increased by half-hourly or user-specified time increments and the network balanced using the flow demands for that particular time of day. Levels of reservoirs are continually adjusted, pumps are started and stopped and valves are opened and closed or set to throttle.  The time of valve and pump changes is calculated on the basis of the system's control logic.  The simulation can be as short as one instant in time or extend for up to 60 days.

Data

Data preparation for the program facilitates simulation of very complex network arrangements.  For simple network and pump operation, data reduces to a very simple form that is quickly prepared.
Data can be imported and exported in a range of formats.

Functions

Using WATSYS / WaterMax, a user may:

  1. Create and edit the configuration and parameters for small to large water networks.
  2. Classify the network into topological 'zones'.
  3. Classify components into construction 'stages' and select which stage of construction to include in the simulation.
  4. Perform a simulation of the network as it would operate over a chosen period of time.
  5. Analyse the systems response to fire flows drawn from a nominated point in the network.
  6. Quantify the flow versus head-difference characteristics ("system curve") for a nominated control valve or pump site.
  7. View maps, graphs, tables, vertical long sections and animations of a number of dynamic parameters including:
    • liquid balance
    • occurrence of system deficiencies.
