ABSTRACT
In India, the rural population accounts for more than 68 percent of the overall population. The lack of a domestic water tank is a serious issue in this location. To overcome this challenge, novel design and solutions to existing problems are required, which is why an elevated storage tank research is being conducted. The purpose of this article is to investigate the design of an RCC overhead tank, and the analysis is carried out using STAAD PRO software.
With reference to IS 3370: 2021, this project summarizes the philosophy underlying the construction of liquid retaining structures utilizing the limit state technique. Water tanks are commonly used for water storage. Water storage is critical since it is used so frequently in daily living.
Keywords STAAD PRO, Analysis and design, Water tank, IS Code 3370.
I. INTRODUCTION
Water tanks are storage containers that are used to store water for everyday use. Water for human consumption is frequentlystoredinthesetanks.Watertanksareusedtostoredrinkingwater,irrigationwater,agriculturalwater,andfire water,amongotherthings.
The major goals of water tank design are to offer safe drinkable water over a lengthy period of storage while also maximizingcoststrength,servicelife,andperformance.
Tamgaonvillage,KarveerTaluka,Kolhapurdistrict,isthesuggestedlocationforourproject.Ourlocationislocatedinan area with ideal natural conditions for the building of an elevated overhead tank. This place is one of the emerging areas that has had a fast population rise in recent years. We chose an elevated water tank among the three primary types of watertankssincethearearequirespressuredwater.Themanytypesofwatertanksareasfollows:
Undergroundwatertank

Rectangulartanks,circulartanks,andintztypetanks,i.e.overheadservicereservoirOHSR,canbecategorizedastanksin terms of design. Rectangular tanks are used for lesser volumes. For big capacity, they become uneconomical. Up to 7,50,000litersofwatercanbestoredincircularoverheadtanks.Thedesignmethodofwatertanksarethree,

Limitstatemethod
The working stress technique of design, which was popular in the past, has a number of drawbacks. Working stress approach can be used as an alternative to the limit state method in cases when it is not practical to use. The limit state approachislikelytototallyreplacetheworkingstressmethodinthenearfuture.Astocl.18.2ofIS456:2000,thedesigner stillhastheoptionofselectingthedesigntechnique.
The limit state design method, which IS 3370:2009 adopted, has the following advantages: limit state design method considersmaterialsaccordingtotheirproperties,treatsloadsaccordingtotheirnature,structuresfailmostlyinlimitstate andnotinelasticstate,andlimitstatemethodalsochecksforserviceability.

Khare, Mr Dushyant kumar Sahu A prestressed concrete water tank laying on the ground was studied for its economic analysis and design. Two tanks will have the same capacity and be made of M20 concrete. One of the project's goals is to conduct an economic analysis and design of both tanks that will be placed on the ground. RCC circular water tanks are thicker and more expensive than prestressedconcretecircularwatertanks.Asaresultofthesefindings,aprestressedconcretecircularwatertankiscost effectivetoconstruct.
