Hi,
The update I promised after our investigation of water use by retail lots…
We installed a couple of sub-meters to get a better idea of what these premises were using. What we found, much to our surprise, is that the 3 most water-dependant businesses – 2 hairdressers and 1 nail parlour – between them only average 1kL/day. That's out of an average of 53kL/day for the whole building. So at least in our building we now know that the commercial lots are not being overly subsidised by everyone else, and it all comes down to what individuals do in their units.
I'd still be interested to know the impact of restaurants and laundromats in other buildings!
Cheers
Chris
