For me personally the level 6 restrictions don't apply - yet!
I'm on 100% tank water; we have no town mains at all.
However, I work in Shopping Centres and I'm up to my arm pits sorting 'compliance' for every drop of water that runs through the place.
Meters on supply pipes, flow restrictors under the sinks, waterless urinals, dual flush toilets, bleed meters on the A/C cooling towers and on it goes.
The water issue has become it's own self perpetuating industry.
Forms for this and that, weekly meter readings, on the spot audits, threats of fines...
Yep, it's all important but I can't help think some of the rules and regs are being put in place as a means of being seen to be doing something.
But it's a good wake up for the wasteful amongst us.
I can't see we'll ever lose restrictions entirely - maybe back to level two if the Country gets back to normal?
