Have Capetonians been restricted to 400 litres a day, as KZN was back during the drought in the 80s?  Are negligent or criminally ignorant people charged?
Do people who have a high water bill not think to themselves "Oh, yes, I might have a leak!"  Have people learnt to change a tap washer?  Are people still using their washing machines daily?  Do people save bath water to flush loos?  If it's yellow do they let it mellow?  Have people put bricks in their cisterns?  Is there a community feeling that we are all in this together, or has that awful modern idea of "what's in it for me?" taken hold?
