Graduates of installer’s course

Interested in learning all about greywater and installing systems professionally? This course is designed for people with either basic plumbing, landscaping, or permaculture skills who want to learn how to design and build simple, economical residential greywater systems.

You will learn about the theory behind simple and high-end systems including the indoor use of greywater. We’ll cover basic plumbing and landscaping skills needed for the four types of common simple greywater systems. You will learn how to conduct a site assessment, determine which system to install and how to maintain existing systems. By the end of the course you will know about proper installation of code compliant washing machine, and simple systems under the state codes of California, Oregon, and Washington.

There will be an exam and installation for people wishing to be certified and listed on our website. The “installer’s page” contains contact info for graduates who wish to be listed, as well as an internal list serve for installers to share info, experiences, and get support.

We’ll be designing and constructing several greywater systems as part of the course.

What past participants have to say:

My favorite part of the course were the instructors, which I found incredibly knowledgeable and well prepared. I really liked the balance between the lecture and hands-on exercises. As someone who has designed and taught career educational classes, I think this course was designed masterfully and worthy of emulation. Instructing adult learners from a wide variety of levels is not easy. –Dorsey Moore- Principal- Sustainability for All

I really loved it all, it was a great balance of classroom hands-on stuff. The instructors were admirably prepared and incredibly generous. I really appreciate the balance of theory and practice. -Leigh Jerrard- owner of Greywater Corps and architect

Awesome experience, highly recommend it and I admire you both. My favorite parts were the exercises, the groups and the final project because it really showed we had learned. Having it set up this way is geniusDeva Luna- landscape contractor and Designer/Manager at EarthCare Landscaping

The 5 day installer course was amazing! The teachers were both very patient and knowledgeable…. I found it very reassuring that the instructors were teaching systems that they had personally installed. They knew what worked and what didn’t from experience. It was neat to meet such a variety of people in the class such as landscapers, other plumbers and people that just wanted to install their own greywater systems in their own homes… I have gone from being a residential plumber to installing greywater systems and rain harvesting systems full time. I still refer to the useful handout binder that I received during the course when installing a greywater system. I felt very confident installing even the very first system I did on my own– Brian Munson – plumber (and now a Greywater Action instructor)
