Sectional Cold Water Storage Tank Capacity Types

Nominal vs Actual Capacity for GRP Sectional Water Storage Tanks

Nominal Capacity is the volume of the tank when it is filled to the brim.

Actual Capacity is the volume contained within the tank up to the maximum working level. This is dependent on the inlet size and air gap selection.
