Here in Ohio we generally use the Ten State Standards per local guidelines. The Ten State Standards provides this figure and formula ...

Once you have determined the peak flow rate into the sump the minimum design volume necessary would be: V(min) = Q(out)*T(min)/4 Q(out) = the pumping rate which is assumed to be half of the peak inflow rate. T(min) = Minimum cycle time between pump starts. If the pump rate is NOT half of ...
