Abstract

Manual scavenging, the practice of manually removing human waste from sewers and open drains, remains a severe social and health issue despite being officially banned in many countries, including India. This practice exposes workers, often from marginalized communities, to hazardous conditions, including direct contact with toxic waste and harmful pathogens. Manual scavenging, especially the removal of clogs from manholes, is a dangerous and inhumane practice. The current method, which involves human intervention without safety equipment, poses severe health hazards to workers. This practice endangers workers' health due to unsanitary working conditions and the lack of safety equipment. Despite legal prohibitions, this practice continues due to the lack of effective technological alternatives. This paper proposes the design and fabrication of a Manhole Clog Removal Machine to address these issues. The machine is equipped with a tilting bucket, telescopic guide, and rotational mechanism for efficient clog removal. Through this mechanized solution, human intervention in hazardous environments is minimized, thus reducing health risks and fatalities.Testing shows that the machine performs efficiently under real-world conditions, providing a viable and cost-effective alternative to manual scavenging.
