Building a DIY Wetland

A family in Australia has created their own tiny wetland as a part of a household grey water system. It is a fairly large DIY project, but, as the article demonstrates, not an overwhelming project. The writer even enlisted his young children to help in the construction.

Black water is toilet waste and other water that requires more substantial treatment. Grey water is non-sewer waste water from washing clothes and showers and the like. Although in most homes, both black water and grey water go into the sewer system and are handled in water treatment plants with the same processing, grey water really requires much less treatment. It is possible to find other uses for grey water, including using the water for toilet flushing or for irrigation.

Low Impact Living: Save Water with the Rainwater Pillow

Editor’s note: Just like our friends at Low Impact Living, we’ve got passion for saving water… so we were very happy to see this post about a new technology for homeowners interested in doing just that! LIL writer Jason Pelletier originally published this post on Wednesday, May 28, 2008.

I’m often pleasantly surprised at how much interest and passion you (our visitors) display for water-saving technologies. Renewable energy is sexy, and eco-friendly cars are top-of-mind for most people these days, but graywater systems? Rain barrels? Rain gardens? Even water-conserving toilets and showerheads? They’re pretty hot too … I for one am thrilled, for not only have I spent a good part of my career designing stormwater treatment systems but I believe that water shortages are a pretty pressing and difficult environmental challenge that doesn’t get enough attention in these days of $4 gasoline and global warming.

The beauty of any of these water-saving technologies is that a) they achieve multiple benefits, saving water while reducing wastewater or stormwater runoff and b) you can see the results right at home. It’s pretty satisfying to open the valve on a rain barrel, see the water flow out and know that you reduced pollution downstream and also prevented water from being siphoned from lakes or rivers tens or hundreds of miles away.

There are some challenges, though. In order to really make a dent in your runoff, you might have to use ten or more rain barrels - not so great if you don’t have space or your downspouts are on the visible side of your house (or if you’re not Ed Begley Jr and just don’t care!). Cisterns give you more capacity, but you’re talking about a real construction project with some possible permitting hurdles.

Book Review: Off the Grid Homes - Case Studies for Sustainable Living

Off the Grid Homes combines beautiful images with technical information for sustainable homes.

The book by architect Lori Ryker is less of a manual for systems to be used in off the grid homes (though it does include good information about the systems and strategies that are used in sustainable off the grid living) and more of a showcase of state of the art homes at the intersection of appealing architecture and high sustainability.

For many, the phrase “off the grid home” brings associations of a rudimentary, hand-built, rustic cabin. It usually suggests a rough hewn character and images of anything other than refinement and elegance. But that image is far from the case in examples presented in this book.
