Hi all,

I live in metro victoria, and I'm installing a water tank or two in my
back yard. I have lawn that I never water, and a moderately large
vegie garden. Any idea about what capacity I'd need to look at?

My current plan is for 2 tanks totalling around 9,000L. Is this
enough? Way too much? I'm new to all this

Future plans include hooking the rain tanks up to the toilet cisterns,
perhaps even the washing machine.

Thanks!

Tom.

I have a 10000L tank for the vege garden (about 10m square) and it lasts 4-6
weeks if there is no rain and I have to keep watering weekly. So 9000L is
not far too much. As others have said it also depends on your likely
rainfall and catchment area. Consider also that most houses have guttering
set up to run to several downpipes, unless you put a tank under each or go
to the expense of re-running the guttering to go to fewer places you may not
be able to harvest all the water off your roof.
