Design of a portable, automated sewer-line inspection and de-clogging sewer-bot for Indian conditions

Abstract

Sewage system in India is a complex system where construction of manholes and sewage pipes generally do not confirm to standards in their operation and maintenance. Numerous challenges include poor construction, unauthorized (nonstandard) connections, rodent damages, and cross connection with other systems such as stormwater drains. Deaths due to asphyxiation and manual cleaning (though banned by law) are not uncommon. The available mechanism for technology-driven automated solutions is expensive, and often not viable in congested settlements. Portable devices available abroad for inspecting pipes and sewers are very uncommon in India. There is a need for tools and devices which are capable of inspecting and potentially removing minor clogs from the sewer lines and are operable by the workforce the authorities already possess with minimum training and aid to the periodic inspection and maintenance of the sewer system. This paper discusses the conceptual design for a sewer-bot which can inspect and de-clog in the rugged Indian environment, and the device is expected to be operated by the poorer section of society generally involved in the upkeep of sewer lines, with dignity and livelihood enhancement.
