Unblocking India's sewers... by hand

It's dirty work but somebody has got to do it - except the practice of removing human excrement and sewage with people’s bare hands was made illegal in India 25 years ago.

But that doesn't mean people have stopped doing it.

It’s called ‘manual scavenging’ and the Indian government estimates that there are around 600,000 ‘manual scavengers’ out there.

Official estimates say that one worker dies every five days in India doing this type of work – but campaigners have told Newsnight this is the tip of the iceberg as many deaths go unreported.
