Ending Inhuman Practices: Transforming Existing Sewerage System into Innovative Rotating Siever Pipe System
Abstract
The existing sewage system in India emits dangerous gases such as carbon dioxide (CO 2 ), hydrogen sulfide (H 2 S), and methane (CH 4 ). These gases pose health risks, sometimes resulting in fire hazards or, in severe instances, fatalities of manual scavengers. The Government of India introduced The Employment of Manual Scavengers and Construction of Dry Latrines (Prohibition) Act in 1993 in an attempt to ban manual scavenging. However, casualties related to such practice can still be witnessed in different states of India. There have been recent studies related to the usage of machines or robots to address this issue. But what if we could avoid the need for someone or something to enter the manhole by altering the drainage system itself? A new drainage system called the ‘Rotating siever pipe system’ was designed and proposed to prevent manual scavenging. The name ‘Rotating siever pipe system’ is relatively self-explanatory. ‘Siever pipe’ is a new term for the pipe in the sewerage system, with mesh-like structures that sieve particles. This helps liquid and solid waste travel and be collected separately. The term ‘rotating’ represents the pipe system rotates around for self-cleansing and prevents clogging. This system is expected to eliminate the need for manual scavengers, ensuring the safety of both scavengers and the environment.
