We have installed 4 tanks for the garden and a tank for excess water, to

'worth' the money, as water in Australia is so cheap.

The available water might prove its worth if you are in bushfire area.

Do you think Sydney is going to have even more severe water shortages
than it has now ? From recent 'studies' it indicates that this will be
the case.

Sydney to experience up to 100 days per year when the temp exceeds
30 degrees by mid-century, if some predictions are to be believed.
Well, that part of Sydney which is still above water after the polar
ice has melted and raised the sea levels. :-(
