E142: Rainwater Harvesting, Purification, and Sanitation

Rainwater Harvesting

In this episode, we sit down with Trenton Kaminski, an expert on rainwater harvesting. His YouTube channel on building your rainwater harvesting and purification system is a must for anyone who wants to set up their system. Trenton shares with us his rainwater system goes into details on the parts and processes he’s used and why he’s used them, and busts the myth rainwater harvesting and purification system are expensive.

In a special second segment, Mark Vorderbruggen, Ph.D. joins us for a discussion on the difference between purification and sanitization. He also educates us on the differences and practical applications of mechanical and chemical purification processes.

Rainwater collection seems simple enough–until you start diving into the topic. You quickly realize it’s not as simple as catching and storing rainwater. There’s a lot to consider: rainwater harvesting, filtration, purification, sanitation, and storage.

But today’s guests break it all down for you and make a BIG topic approachable.
