Sign up here.

Questions for you:

  •  Do you (or your customers) want to stop wasting water and start reusing greywater in the landscape?
  • Do you feel uncertain, confused, or overwhelmed by all the different options and considerations with greywater systems, and want support deciding what is best for your situation?
  • Whether you hire someone or build it yourself, do you want to feel confident your system will work well, and not cause any unforeseen problems with your plants or plumbing?

If you answered yes to these questions, Greywater Design Mastery will give you the results you are looking for.


By the end of this program you will:

Week 2: Assess your site to consider your plumbing, soil type, slope and setbacks, and plant choices

  • Have your system fully designed.

  • Feel confident you’ve chosen the best system for your situation.


In this program you will get access to:

  • Live group coaching sessions to plan, assess your site, and design your greywater system (includes recordings of any live session in case you miss it).
