[Strawbale] rainwater catchment for toilets?

[Erica Konrad]

We are currently building our strawbale home in Nelson, BC and our local 
municipality will not let us use our rainwater catchment system (buried 
rainwater cistern) to feed our toilets.  The plan is to use it for 
irrigation and toilets.

Our building inspector thinks we're ahead of the curve yet his concern is a 
backflow preventor at some point will fail and contaminate City water. 
Existing infrastructure and policy does not allow for rainwater catchment to 
be cross connected with City water.

Does anyone know any municipalities in Canada that allow this, so that I can 
take it to Council as an example? Any advice?

Thanks in advance,
Erica
