3. INTRODUCTION Water is the lifeline for every living creature on this planet. Liquid storage tanks are used extensively by municipalities and industries for water supply and maintaining ecological balance. Access to clean and safe water is fundamental to public health and community well-being. Water tanks plays a vital role for public utility as well as industrial structure having basic purpose to secure constant water supply. Overhead water tanks are pivotal in managing and storing water for residential, commercial, and industrial use. These tanks help maintain water pressure in plumbing systems, ensuring that water is available at required heights and flows efficiently through pipelines. Importance of Water Storage Consistent water supply Pressure management Firefighting and emergency storage 3

5. INTZE Water Tank Design Design Efficiency INTZE water tanks are known for their efficient design. The design incorporates a conical bottom and a cylindrical shell, allowing for an optimized distribution of forces and increased structural stability. This unique shape minimizes material usage while maximizing storage capacity and durability, making it a cost-effective solution for large-scale water storage. Unique Design for Maintaining Water Pressure One of the distinctive features of the INTZE water tank is its ability to maintain consistent water pressure throughout the distribution system. The tank’s design ensures that water pressure remains stable, regardless of the varying levels of water inside the tank. This is achieved through the strategic use of gravity and the tank’s conical bottom, which helps to evenly distribute the water pressure. As a result, buildings and facilities connected to an INTZE tank experience a reliable and steady flow of water, essential for both daily usage and emergency situations. 5

LITERATURE REVIEW 8 Issar Kapadia , Purav Patel, Nilesh Dholiya , Nikunj Patel7 “Analysis and Design of INTZE Type Overhead Water Tank under the Hydrostatic Pressure as Per IS: 3370 & IS: 456 -2000 by Using STAAD Pro Software”, Water tanks are important public utility and industrial structure. The design and construction methods in reinforced concrete are influenced by the prevailing construction practices, the physical property of the material and the climatic conditions. Before taking up the design, the designer should first decide the most suitable type of staging of tanks and correct estimation of loads including statically equilibrium of structure particularly in regards to overturning of overhanging members shall be made.   Hasan Jasim Mohammed (2016), conclude that: An application of optimization method to the structural design of concrete rectangular and circular water tanks, considering the total cost of the tank as an objective function with the properties of the tank that are tank capacity, width and length of tank in rectangular, water depth in circular, unit weight of water and tank floor slab thickness, as design variables .. The results shown that the tank capacity taken up the minimum total cost of the rectangular tank and taken down for circular tank. The tank floor slab thickness taken up the minimum total cost for two types of tanks. R.V.R.K.Prasad and Akshaya B. Kamdi (2012), Storage elevated water tanks are used to store water. BIS has brought out the revised version of IS 3370 (part-1&2) after a long time from its 1965 version in year 2009. This revised code is mainly drafted for the liquid storage tank. In this revision important is that limit state method is incorporated in the water tank design. This paper gives in brief, the theory behind the design of circular water tank using WSM and LSM. Design of water tanks by LSM is most economical as the quantity of material required is less as compared to WSM. Water tank is the most important container to store water therefore, Crack width calculation of water tank is also necessary.

9. Conti… Thalapathy . M and et.al : Storage reservoirs are used to store water, petroleum products and similar liquids. The tanks are designed as crack free structures to minimize leakage. This report provides the detailed analysis of the design of liquid retaining structure using working stress method. The project deals in the design of reservoir in 1) Underground Tank, 2) Tank Resting on ground and 3) Overhead water tank. The paper gives information for safe design with minimum cost of the tank. In order to make design of tank more economical, reliable and simple. The paper taught us about the design philosophy for the safe and economical design of water tank. Bugatha Adilakshmi and et.al: . Basically tanks are designed as crack free structures to eliminate any leakage. Here, Working stress method is used to design an INTZE tank and Elements of the tank are designed by limit state method. Usually, for a given capacity, circular shape is preferred because stresses are uniform and low when compared to other shapes.. This project deals in theory, design and analysis of the INTZE type water tank. The main point of this paper is to give best estimates of the required quantity of concrete and steel for a given water capacity. 9

14. CONCLUSION The design and analysis of overhead INTZE water tanks are crucial for ensuring a reliable and efficient water storage and distribution system. The meticulous design and thorough analysis of water tanks are paramount to their performance and safety. Proper design ensures that the tank can withstand various loads, including water pressure, environmental forces, and seismic activities. Comprehensive analysis helps in identifying potential vulnerabilities and optimizing the tank's structure to enhance its durability and functionality . Adhering to established standards, such as those outlined by the IS codes, is essential for ensuring the safety, reliability, and longevity of water tanks. Elevated circular water tanks with large capacity and flat bottom needs large reinforcement at the ring beams. To overcome this in intze tank, by providing a conical bottom and another spherical bottom reduces the stresses in ring beams. Intze tank is more economical for high capacity reducing the steel requirement. 14
