Expert Solution
Step 1

A water storage tank is a structure that is used to store water for storage, distribution or treatment purposes. They are generally massive in size and accommodate large volumes of water.

Thus, we need to consider the weight of the empty tank as well as the weight of water at full capacity to design the walls, base and footing of the storage tank because of the significant stresses these parameters can induce in the storage tank components.
