Comparative Study of RCC Water Storage Tank with IS3370 Old and New Provision

Water tanks are the storage containers for storing water. The water tanks project have a great priority as it serves drinking water for huge population from major metropolitan cities to the small population living in towns and villages. This project shows the design of comparative evaluation of RCC water tank with between old and new provision. BIS has recently revised IS 3370 code of practice for concrete structures for storage of liquids. As per the provisions of code IS 3370: 1965, the method which is adopted for designing the water storage tank is working stress method only. In the new provision of IS 3370:2009 adopts both working stress method and limit state method. In this project, comparison of the design provisions of IS 3370:1965 and IS 3370:2009. In IS 3370:2009 limit state method considering two aspects mainly it limits the stress in steel and limits the crack width. All tanks are designed as crack free structures to eliminate any leakage. This project gives the detailed analysis of the design of liquid retaining structure using working stress method and Limit Stress Method. The project also gives the design of Reinforced cement concrete water tank.
