Ask anyone who is fortunate enough to live in one of the minority of the world's households with a flush toilet what happens to their sewage, and the answer would most likely be: 'I don't know and don't want to'. But with six billion people in the world each producing 550 litres of excreta a year the world's waste is going to waste. This Hands On programme lifts the lid on the world's toilets: we go down the drain in Karachi, get a worm's eye view in Ireland and sit with the Swedes in Stockholm.
