Please enter ten years of monthly rainfall data (in mm) below. Each
month should be followed by a comma. (e.g.74,58,106,195,164,103,104,104,128,127,120,67).
If you only have MEAN monthly rainfall figures, copy the same 12 figures
into every row
Three water management strategies are available. Choose from the following:
The user draws a set amount of water from the tank every day
if there is enough in there to do so, otherwise the user takes
what is left in the tank.
Varies with tank
The user draws off an amount dependant on the volume of water
in the tank. If the tank is between one-third and two-thirds full,
the user takes the nominal demand that you specified from the
tank. If the tank is more than two thirds full, the user draws
off more water than usual, but if the tank is less than one third
full, the user takes less water than normal. This water conservation
means that system reliability is improved for a given tank size.
Varies with season
The user takes more water from the tank if it has rained recently
and less when it has not. This aids water conservation and increases
system reliability for a given tank size.
Note: This option may take over a minute to process
- please be patient before hitting the "stop" button.
