Simulate the transient behaviour of water supply distribution networks.  The specialised tool simulates most enclosed pipe hydraulic installations likely to be met in practice.  It is most often used to assess and protect systems from damage caused by pressure surges.

In systems transporting a very large water mass it can help assess how long it takes the system to respond to pump status and valve position changes under automatic control.

WATHAM handles most combinations of:

c  Pipes
c  Reservoirs (Tanks)
c  Pumping stations and pumps
c  Restrictions
c  Check valves
c  Control valves
c  Pressure relief valves
c  Surge tanks
c  Pressure vessels
c  Air cushions
c  Air valves
c  Anti-vacuum valves
c  Vent-O-MatTM air release valves
c  Small diameter standpipes
