Q: How can a reservoir level be predicted to go up when it is below minimum and no pumps/valves are scheduled on to fill it?

Oct 19 2010

A: If a reservoir level is below the minimum limit this breaches a primary constraint. There could be many reasons for this including bringing a tank back into service or recovery after pipeline or pump station failure. To allow the Aquadapt Solver to find a solution we make it assume the storage tank it is at minimum level at the start of the solve period. Aquadapt software may then show the tank level at this level which is greater than the actual level for the next period even when nothing is actually filling the reservoir. Normally back up level control will ensure the tank stays above minimum. We indicate that this is not a true indication of level by shading all of the level values on the screen grey instead of blue to make it more obvious that this level data is invalid.
