Abstract: Increasing water demand due to population growth and lifestyle changes emphasizes the significance of water tanks in water supply projects. Overhead water tanks enable gravity-based water supply without the need for pumps, prove effective for both domestic and industrial use. Diverse tank shapes are analyzed to achieve optimal aesthetics and cost-effectiveness. Modern trends, especially in religious locations like Mahakal Lok in Ujjain and the Kashi Vishwanath Corridor in Varanasi, involve structures designed to match the historical context. The current study focuses on a "Kalash" shaped overhead tank, with a hyperboloid shell of revolution at the top and a spherical shell at the bottom. The study explores "Kalash" shaped tanks analyzing different capacities under various fill conditions and loads. The analysis, conducted using the STAAD-Pro software, identifies critical zones for stress concentration, moments, and shear forces. Keywords: Finite Element Method, Kalash-shaped tank, STAAD Pro
