The water and sanitation target is simple and unambiguous: by 2030 every man, woman and child – whether at home, school, hospital or their workplace – should have access to a safe water supply and be able to go to the toilet in a clean space with privacy. We just have to roll up our sleeves and get on with it, some would say. In fact it is harder than that.
That the target exists and is agreed to is great, and it will be very obvious whether it is achieved or not. But all our experience and the latest data point to one unavoidable fact: we need to act faster. We need one change so great that it requires a complete transformation of the water and sanitation sector, and how it is financed.
