Enormous research has been made to meet the water demand either
commercial or public via R.C.C (Reinforced Cement Concrete) tank supply,
meanwhile minimal researches are made on Overhead Rectangular R.C.C
water tanks. Tanks are commonly used as storage structure, which can be
either below or above the ground level to store water, liquid petroleum,
petroleum products and similar liquids. This project emphasizes on
analytical comparison to justify the effectiveness of overhead
rectangular water tank for nominal capacity in terms of material
feasibility designed by approximate method and IS code method. When
compared, several parameters such as moment, direct tension & depth of
vertical walls as well as slab got analysed in which IS code method
overwhelmed approximate method. IS code method have been proved
economical & feasible during design. The elevated tanks are supported on
the leveled R.C.C framed staging. The walls of these tanks are subjected
to hydrostatic pressure and the base of the tank is subjected to weight
of liquid with its self-weight. The base slab performs structural
function to bear the weight of water stored and can be designed using
Working State Method (WSM).
