Preventing Flotation of Underground Storage Tanks

The answer has to do with buoyancy. Think of a half-filled water bottle. If you toss it into a body of water, it floats, because the air in the bottle exerts an upward force known as buoyancy. The same concept applies to underground storage tanks. If the water table reaches a high level or if flood waters reach a high flood stage, the air in ...
