Happy World Toilet Day.
In this space, to the best of my knowledge, the water world is still years ahead, with increasingly sophisticated discussions around who pays for what (users, governments, private financiers) – all along the service delivery chain.
Last year on World Toilet Day, while my escaped poo was on the loose and generally making a nuisance of himself, I wrote that the way to put him permanently in his place – and out of harm’s way (for the rest of us) – was to build strong and resilient sanitation systems with toilets/latrines.
In the meantime - I expect that many of my (and your) poos will be around to bother us for a while to come!
On the positive side, I’d say that the shit flow diagram continues to be about the single most powerful systems level analytical tool that we have – in either water or sanitation.
