STORAGE TANKS

Storage tanks are subterranean with approximately one-third of the structure appearing above the land surface.  Each tank has a capacity of 180,000 litres and tanks are normally clustered in groups of three.

The exterior of the tanks is armour-plated but they can be penetrated by shell, missile or heavy machine-gun fire. Usually a few direct hits by shell or missile fire will render a tank unserviceable. However, they will withstand a considerable amount of machine-gun fire.
