At Roland: We do try and do that too. Our landscapes for the most part are desert adaptive so that does help in water conservation. Thanks for the great feedback, I will keep that in mind with the next project. We actually just finished a project where we did this exact same thing!
At Jason T. Radice: I would like to try and use grey water for irrigation and toilets, and we can do that to a certain point but not with reclaimed water from rain barrels. We do use natural infiltration to naturally purify the water as well as irrigation. I am not sure about the law on condensate, I will look into that! Thank you for the great comment. It is always great to get a different perspective on the subject!
