Q. Have you ever heard of filtering greywater through a DIY Backyard Wetland? I recently read a zine by The Guerilla Greywater Girls called A Guide To Water, and it has a bunch of DIY greywater things anyone can do. One of the things that they have is a “Greywater Wetland Filter.” It has a surge tank, then a sand filter, then it goes into a tub filled with gravel that has wetland plants growing in it. I was just wondering if you had any tips on this topic.
A. Yes. In fact, it’s called a “greywater reed bed.” We started building something similar in our backyard but have had to stop the project while we work on tearing off our old asphalt shingles off our house so that we can put a environmentally friendly metal roof on. With the metal roof, we will then be able to collect and harvest rain water.
OK back to your grey water question:
I would recommend you visiting this site http://www.oasisdesign.net/greywater/ where I will think you’ll find some very helpful information.
We have an outdoor shower where the “greywater” seeps into the surrounding soil and waters the edible plants. We also funnel the wash water and allow it to percolate into the mulched soil – very low tech solutions.
Like I said, we are working on being able to take our bath water and sink water from inside the house and build some sort of greywater pond that will filter the water — but that’s on hold at the moment.
