The rail ministry said "no" in the Lok Sabha on May 4 when asked whether it is India’s largest employer of manual scavengers – sanitation workers who clear human excreta, a banned practice – disguised as sweepers.

The railways said they used floor scrubbers and vacuum cleaners within trains, and high-pressure water jets in most rail depots where the Rajdhani, Shatabdi, Duronto, mail/express and passenger trains originate.

Other employers of manual scavengers – almost all of whom are Dalits, the lowest of Hindu castes – include the army and urban municipalities. Like the railways, these organisations also hire them on contract so that they do not appear on their rolls. One Gujarat region has now ordered an inquiry after such contract workers were found cleaning sewers without protective equipment.

The Indian Railways is the largest employer of manual scavengers, with an unknown number on their rolls, IndiaSpend reported in November 2015. Most “sweepers” – as they are called, to mask their identity as scavengers – with the railways are employed through contractors, and they earn around Rs 200 per day, the portal reported.

As many as 12,226 manual scavengers were identified across India – 82% of these are in Uttar Pradesh – according to a reply to the Rajya Sabha (Parliament’s upper house) on May 5 by Minister of State for Social Justice Vijay Sampla. These are clearly under-stated official figures. Gujarat, for instance, admits to having no more than two manual scavengers, according to government data.

Yet, as IndiaSpend reported in May 2016 in collaboration with Video Volunteers, a global initiative that provides disadvantaged communities with story and data-gathering skills, in one Gujarat town, Dalits were at work in the sewers.

Play

The video shows how Umesh, 23, a young man belonging to the Valmiki caste, cleans sewers in the town of Dhrangadhra without protective gears and cleaning equipment, a non-bailable offence under the Prohibition of Employment of Manual Scavengers and their Rehabilitation Act (2013).

Widespread issue

Dhrangadhra chief executive officer Charu Mori denied the existence of manual scavenging at the time. “These workers are not our responsibility since they are hired by a contractor,” she said. “I am well-aware that such actions are illegal and thus the municipality does not engage any manual scavengers.”

After launching an online petition, Video Volunteers cajoled the government into action.

The district collector of Surendranagar, which covers Dhrangadhra, was scheduled to meet with the CEOs of seven municipalities in the district to investigate manual scavenging in the region. The meeting was twice postponed and is currently scheduled for August 29.

The issue was brought to the notice of the district collector by Video Volunteers on August 1, when it submitted the video, along with a protest petition signed by 20,000 people, demanding action against Dhrangadhra municipality for violating the law.

There are 1,67,487 households that get employment by manual scavenging in rural areas, according to data released by a 2011 government socio-economic survey.
