To be mention here in necessity is mother of invention have personally been experienced by me when it came to clean the overhead water tank of my house at that time I noticed that how difficult it is to climb and do the required cleaning of overhead tank it was revealed that there is a need of designing a semi- Instance automated overhead tank cleaning system. The current procedure used for cleaning and draining of overhead tank is requires a lot of manual handling. Which seems to be very difficult so with this intention I came up with the solution of overhead tank cleaning system which should be portable and comfortable to handle This system will help in increasing the safety of the workers, the working efficiency and saving the time and efforts of the workers, working principle of the system is that the water is released with pressure from the nozzle .The pressure and the speed of the water flowing or coming out through the nozzle is use for removing the dirt from the surface of the tank. To generate required pressure and the speed of the water high pressure pump is used .high pressure reciprocating plunger / piston pump develops high pressure due to smaller diameter orifice of the nozzle, which develops high pressure which in thru converts in to high velocity causing water jet blasting on the surface of the overhead tank. Appropriate flow rate and pressure can easily clean the overhead water tank. This report is focus on the study and design of a tank washing system .The redesigned model will thus help in reducing time in carrying out the cleaning operation and reduce the user’s effort required for cleaning..
