Wells & water/ CALCULATOR

Tank fill time with simultaneous demand

Estimate how long a tank takes to reach capacity when water is entering and may also be used.

Tank capacityLUse the working full level, not overflow volume.

Starting water volumeLEstimate volume at the start of the fill period.

Average inflowL/minUse measured sustainable inflow during this period.

Simultaneous outflowL/minEnter zero if no water is used while filling.

Constant inflow and outflow, known starting volume and no leakage, overflow, pump cycling or changing well yield. Measure a real fill interval when commissioning controls.

Well supply and peak-demand buffer

Compare a measured source flow and usable stored water with one defined period of peak household demand.
