Water tanks are classified on bases of their shapes and position of structure. In this paper, we had discussed about the design of water tanks of overhead circular, overhead rectangular and underground rectangular tanks are designed and analysed using STAAD-PRO. All tanks are designed as crack free structures to eliminate any leakage. From the analysis results concluding about the influence of shape factor in design loads and comparing all types of tanks which is most economical. Manual Analysis and design of Water tanks by using IS code method is compare with STAAD-PRO design result, comparison of reinforcement is done and optimize results are determined. After completion of project we do estimation of all tanks. All water tanks of 5MLD capacity is designed.
