Generally, the water tanks in India were structurally designed by working stress method, as endorsed in IS 3370-1967.This code was overhauled in the year 2009 and the code permitted the design of water tanks by Limit State Method, along with Working Stress Method , as recommended in IS 3370-2009. This introduction was most anticipated as the previous rendition required the thicker section to permit the crack free structure. It would be truly fascinating to find the progressions introduced in IS 3370-2009. In this paper, a rectangular water tank is designed with reference to the changed and pre-reconsidered adaptation of IS 3370, both by working stress method and limit state method. It was found in the outcomes that the tank designed by limit state method was conservative , as compared to that planned by working stress method based on IS 3370-1967. Likewise, the clause of permitted crack width has been recommended in the revised version of the code. The code permitted the crack width of 0.2 millimeters as limit state of serviceability. It was seen that the steel prerequisites according to new code was observed to be lesser than that in the earlier edition.
