Redesign and construction of an automated water saving public flush toilet :

Abstract

In today’s life, the water borne toilets have a problem of poor sanitation and high spread of UTIs. This are attributed to clogging due to low water pressure, dirty surfaces, continued use of toilets without water, damage of facets due to manual operation. This project aims at improving sanitation through solving the clogging issue by increasing the water pressure, cleaning the toilet pan and also improving the water use efficiency through avoiding multiple flushes. Automation of the system using Arduino helps to prevent the direct contact of the user with the toilet and the spoilage of the system. The low water pressure in the system is boosted by use of the compressor and this solves the clogging issues and saves water. There is therefore need for the redesign and construction of an automated water saving public flush toilet with a compressor to help solve the low water pressure, a self-cleansing mechanism for the toilet seat and an exhaust pipe to suck out the bad smell during the toilet use at a relatively low expense. The results revealed that the amount of water saved is 1314 units of water, water bills saved is 4,955,094UGX and Money saved on medication is 48000000UGX for five years. The longer the time of cleaning of the toilet seat, the larger the area cleaned and the efficiency of cleaning and the same applies to the drying efficiency. That is; at one minute of cleaning, the area cleaned is 20cm2 and the cleaning efficiency is 12% and for 10 minutes, the area cleaned is 60cm2, the cleaning efficiency is 64% which is higher than for one minute.
