The Importance of Materials and Sizing in a System

Rob Avis, of Verge Permaculture, joins me to talk about rainwater harvesting.

This conversation is based on his book from New Society Publishers, Essential Rainwater Harvesting. Rob wrote this book along with his wife and Verge Permaculture Partner, Michelle. Though they began their professional careers as engineers designing solutions in the oil fields, they now live on a productive permaculture homestead in Alberta, Canada, and use that experience to create and share all the formulas, calculations, and components needed to create a productive system for capturing clean, healthy water.
