After a very full-on fortnight learning about permaculture and activism at the Earth Activist Training 2011 course in August, I came away all fired up to make some changes at home. I would absolutely love to set up some kind of greywater reuse system, but given the 40 sq m of garden available in my central London terrace, it would be both a big practical challenge and a pretty poor use of our limited outside space.
However! There is a very straightforward way to reuse some of your greywater, which requires only a bucket. Put the bucket in the shower, where it can catch some of the water you use while you're showering. The next time you need to flush the loo, grab the bucket and pour it down there instead of hitting the flush. There you go: a bucket of water saved per day, with next to no effort.
I started doing this a couple of weeks ago, and can definitely recommend it: both easy to implement and personally satisfying (if you're the sort of person who gets satisfaction from saving water). Sure, it's not a huge amount; but it's more than nothing. Not only that, but I've found myself more aware of the water I'm using whilst showering (and have taken, for example, to turning the pressure down a bit), which is a neat secondary advantage.
Watch this space for more on my permaculture adventures; specifically the plans for the brand-new garden, and my solution to maintaining the allotment next year on what will be a very small amount of available time.
