[Greenbuilding] Living with a rainwater cistern (was Re:hotwater)

[Kathy Cochran]

I would imagine that there is a break-point in average rainfall where
collecting rain off the roof is practical for the collection of water use to
supply a household, and one that grows a vegetable garden to support that
household.  What would be the suggested annual rainfall to make a system
like this practical?  

 

Thanks in advance,

PS  Since I have lived here (10 years) I have seen a variance from 19 inches
all the way up to 46 inches.  Average is considered to be around 30".

How unreasonable is a rainwater system for Canadian winters... Would
the tank size required make it unfeasable?
