Create an Oasis with Greywater

Create an Oasis with GreywaterCreate an Oasis with Greywater seems to be the primary text available on the subject, so if you want to deal with wastewater in an alternative manner, you'll need to get your hands on a copy.  The book is self-published, but the only negative I can come up with is that the interior layout isn't very enticing --- too little white space on the page.  However, I think that Art Ludwig chose the design intentionally so he could fit 300 pages worth of information into a 144 page book, thus cutting down fewer trees and selling the book for a more reasonable price.

That small caveat aside, Create an Oasis with Greywater is a masterpiece.  The fifth edition is completely polished, easy to read, and full of useful information for everyone from the ramshackle DIYer (that's me) to folks living in mansions who want to hire someone to create a high tech lawn irrigation system connected to their washing machine outflow hose.

Greywater systemIn case you've never run across the term before, "greywater" is all of the waste water coming from your house except from the toilet.  The water flowing down the drain of your kitchen sink is definitely not potable, but is generally pretty low in harmful bacteria and can be easily and safely treated with low tech options that irrigate your plants at the same time.  In addition to helping your plants, channeling your greywater to a separate location from your blackwater means you use less energy to treat the latter, which is good for the environment.

To make the best use of greywater, you'll need to be careful with what you put down the drain (something you should be doing anyway), and to understand your specific site conditions and climate.  The rest of this week's lunchtime series will cover a few of the greywater treatment methods that appealed most to me, but I highly recommend finding this book for yourself if you want to delve deeper into greywater systems.

Weekend Homesteader covers the other side of sustainable water use, explaining how to capture rain in a barrel and use it on your garden.

I bought this book seven years ago when I built my house, and I still find myself referencing it. We have had very few problems with the system, and the ones we have are a result of me second guessing Art. Don't do that.

I highly recommend this book.

Eric in Japan --- Which of his systems did you use? Did you post about it on your blog? I'm very curious to hear more about it! (Maybe if you haven't posted about it, you can now? :-) )

It's been a hot dry summer in Ontario. There has been rain in the last week, but June was very dry and it set back a lot of crops. I've been touring and volunteering on organic farms all summer -- I keep hearing about grey water systems -- not installed yet, but people talking about how to do it, especially how to adapt traditional houses to a greywater harvesting system. I read Solviva ( -- she does greywater recycling, too.

J --- Greywater systems are tougher in climates like yours and ours where it gets cold during the winter, which is probably why you hear about so many systems in the planning stages but few in the implementation stages. Stay tuned for later posts in the series that walk you through some potential solutions to that problem.....

Sounds like a fascinating summer touring organic farms!
