The drawdown is the difference between the static and the dynamic water level.
4: What are the two factors that should be ensured when the total head for a ground water pump is calculated?

4: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
There is no suction lift. Instead there is static water table and the drawdown has to be added to the elevation lift.
4: What are the two factors that should be ensured when the total head for a ground water pump is calculated?
There is no suction lift and the drawdown has to be deducted from the elevation lift.
