Rain barrels are a great way to reclaim water from your roof to use in your garden. Scroll down for guides to buying or making your own.
There are lots of great instructions for making rain barrels and grey water systems on the web. Here are three excellent guides via the Slow Ottawa ‘Consume Less’ Pinterest board. Click image for details.
Cisterns & Greywater Systems
