You must read my comments properly and not misrepresent what I wrote. I said an 'estimate the INDUSTRY uses 2000-7500l'. I doubt you read the linked article. The 'industry' is NOT 'a [per] tourist' as you wrote, but tourists AND supporting industry, ie transport, hospitality, entertainment, etc. I quoted an expert (see link) because to my knowledge no local person has quantified it. In another forum I asked a local expert who didn't know. (Or 1.6m x 90l/day excl industry use.)
The fact is De Lille, not I, stupidly said 'the influx of tourists won't cripple water supply if Capetonians save water'. You too say so. Come on, tell us how to do that when we're already at the limit? Must we sacrifice more for TOURISTS?
I'm not 'blaming' anyone except her and city for incompetence. That's why I'm 'indignant'. We can't continue this way - development at all costs, invite visitors, ignore climate change, etc - pretending it's all OK when we have a disaster. You're in deep denial - wake up!
