Get the essential tools, methods, and technical know-how to design and maintain home-scale rainwater harvesting systems

Thinking of harvesting rainwater? Worried about avoiding health hazards and other safety risks?

Be the first in your city…state…or bioregion… to design and build Rainwater Harvesting Systems using leading-edge, safe, chemical-free methods. You’ll find them only in our groundbreaking new program:


Created in partnership with pioneering Australian hydrology engineer, economist, policy analyst, educator, U.N. advisor and independent researcher Peter J. Coombes, Ph.D., this in-depth, step-by-step course is the first to offer scientifically tested and proven information that isn’t widely available in North America! 


  • Learn how a leading-edge RWH system works in relationship to homes, properties, and their surrounding ecosystem
  • Break down the myths and discover what is and isn’t a risk in rainwater
  • Discover the science and research supporting a natural treatment approach
  • See how you can design and build chemical-free RWH purification and storage systems for irrigation, washing – even cooking and drinking!

This course reflects decades of studies by independently funded researchers, particularly in Australia, where over 3 million people drink rainwater daily. The vast majority of these RWH systems do not include end-of-line disinfection… and rainwater-drinking Australians are as healthy or healthier than those relying on municipal treated water.

But that isn’t the only way this exciting program breaks new ground!

Just take a look at our sneak-peek video to experience our brand-new teaching format…

NOTE that the On-Demand version of the course does not include live webinars or Q&A with Michelle and Peter. If you prefer the live course please sign-up for our Newsletter and we will let you know when registration opens for the next live course.

What’s the time commitment for this program?

This is a comprehensive course. To get the most out of the program you should expect to commit anywhere from 4 to 8 hours a week for each module.

Although the lessons are available 24/7 and can be completed at your own timing and pace, we do provide a recommended schedule for the Live version. We will be providing audio-only, downloadable versions for many of the video lessons, with the intent of making it as convenient as possible to get through the content. For instance, you may listen to many of the lessons while you commute.

The webinars for the LIVE course will run over the course of ten weeks, with one live webinars per week. See the schedule on your student dashboard for times. You’ll definitely want to plan to attend those, but if you do happen to miss, know that recordings will be posted to your student dashboard. If you fall behind you may find it difficult to follow along during the live Q&A webinar sessions with the instructors.

I signed up for the On-Demand Essential Rainwater Harvesting Course but would prefer a physical copy of the book, what can I do?

We understand that many people prefer to have their hands on a physical book rather than on a screen, and we are happy to accommodate for those folks. If you prefer a physical copy, all you need to do is pay for the shipping. We send physical book orders out on Mondays.
