With all this water business going on the drought, hose pipe bans, water meters etc.
Surely there must be a way to use rain water to flush the toilets, i'm thinking along the line of if you have a ground floor wc which would normally be with an exterior wall, could you have a water butt or tank collecting rain water and when you flush the toilet the cistern(toilet tank) suck in the rain water from the butt??
any ideas/thoughts? or better even tried & tested solutions?
