The term ‘Water Tank’ generally refers to distinctive liquid retaining structure. It has been developed about 80 years ago and recognized as well-designed, efficient and economical unit for commercial as well as residential use. Also, it is inevitable part of water supply system, and extensively used for storage and processing of variety of liquid like material such as water, petroleum product, liquefied natural gas, chemical fluid and wastage of different forms. Underground water storage tanks (Fig. 1) and (Fig. 2) requires to look for are strength and durability. Leakages can also be avoided by identifying good construction practices.

S. B. Vankudre and professor Prabhavati P presented a study on reinforced concrete water tanks that are resting on the ground and supported on ground directly. In the design they compared the total cost of the tanks which were subjected to different capacity and dimensions. As an objective function with the properties of tank that are tank capacity, width & length etc. The study gives an idea for safe design with minimum cost of the t ank and give the designer the relationship curve between design variable thus design of tank can be more economical, reliable and simple. The paper helps in understanding the design philosophy for the safe and economical design of water tank. The wall of tanks subjected to pressure and the base is subjected to weight of Water.

3.2 Tantetal Presented the minimum cost design of reinforced concrete cylindrical water tanks based on the British Code for water tanks, using a direct search method and the (SUMT). The cost function included the material costs of concrete and steel only. The tank wall thickness was idealized with piecewise linear slopes with the maximum thickness at the base.

Rashed [5] rationalized the design procedure for reinforced and restressed concrete tanks so that an applicable Canadian design standard could be developed. The study investigates the concept of partial pre-stressing in liquid containing structures. The paper also includes experimental and analytical phases of total of eight full scale specimens, representing segments from typical tank walls, subjected to load and leakage tests. In analytical study a computer model that can predict the response of tank wall segments is described and calibrated against the test results. The proposed design procedure addresses the leakage limit state directly. It is applicable for fully prestressed, fully reinforced and partially prestressed concrete water tanks. The conclusions that are drawn are as follows,
• A design method based on limiting the steel stress, does not produce consistent crack or compression zone depths under the application of pre-stressing nor under a combination of axial load and moment.
• A design method based on providing a residual compressive stress in concrete dose not utilizes non-prestressed reinforcement
