Just listening to a radio story about the dryest period in Ca. in recorded history. Here in Northern New Mexico we've not had rain or snow since Thanksgiving. Makes me think of rainwater roof catchment. Here is a simple system we are installing for an off the grid bathroom addition we are building. Water storage and re-use (greywater) are going to become even more relevant as the planet continues to be the home for more and more of us. We should be talking about this and sharing ideas...
