Background: Foundation is known as the base structure of a structural element that allows transferring a load of the superstructure to the soil. A shallow foundation is provided for low-rise buildings. Water tank is a high-rise structure, that is used for storage and supply purposes of water, for more efficiency elevated areas were considered for gravity flow of water. The Foundation of water tank can be designed as per site condition and load capacity of the tank. A weak foundation led to extreme damage to the tank causing loss of money, inconvenience caused to people.
Scope and approach: This case study shows that the foundation of a water tank can be designed either with spread or raft foundation that depends upon the load-bearing capacity of the soil, lesser will be bearing capacity more accuracy, and effective design needed. The study of two different sites and soil conditions is shown.
Key finding and conclusion: The design of the foundation is done manually using IS code. If the bearing capacity of the soil is adequate spread footing can hold, if not raft or mat footing is provided. Foundation design mainly depends on the soil capacity and types of soil.
