Overall purpose for designing & manufacturing a machine was for cleaning overhead water tank. Since we have investigated that the general purpose OHWT which is used by (71%) of people approx. needed to be cleaned more frequency than earlier days where sanitation is done manually twice per year.
According to our research and survey we found that, the quality of water provided by corporation to the public is decreasing day by day. Because of which dirt sediments, fungus and stains are getting integrated on the inside surface of the tank more frequently like every two months. Nowadays 8 out of 10 household have installed water purifier to the OHWT. As the sedimentation &the growth of fungi and bacteria is increased. We need to design & built a machine which can clean the water tank entirely from inside. The brush would be adjustable as per the diameter of tank and it would remove fungus or algae form on surface of tank and further with the use of a pump the water including dirt and sediments will be flushed out the tank.
