Employment of people as manual scavengers was banned in India during 1993. Following this ban, the government proposed a suction lorry for cleaning the manhole on the roads. This lorry was capable of removing only the water from the sewage and not the blockage. Then, a sewage cleaning vehicle was proposed whose usage was confined to the manholes only on the roads. Most of the sewage deaths that were recorded in the past few years have happened at private institutions, schools, colleges, shopping malls, etc. which are not permitted to use the sewage cleaning vehicle. The most important reasons behind these sewage deaths have been asphyxiation and inhaling of hazardous gases such as ammonia, hydrogen sulphide, carbon monoxide, carbon dioxide and methane. This project is proposed to reduce deaths due to manual scavenging using a semi-automatic machine that cleans the manhole using a double bucket arm which is controlled by the user with the help of a pendant. After this process of cleaning is completed, a module with a gas sensor array and a temperature sensor is placed at the manhole head so that the hazardous gases are sensed and the information about the concentration of the sensed hazardous gases is transferred wirelessly through ZigBee. If the concentration level of any of the hazardous gases crosses the threshold set in the Arduino, it raises an alarm in the buzzer. The whole setup is portable.
