Many people join the Tiny Living Movement because they are interested in saving money and/or the environment. Going off the grid is one way that you can help your pocketbook and the planet at the same time. But how “off the grid” can you really be in a tiny house? One of our biggest needs in everyday life is water. We use is for drinking, washing clothes and dishes, and for showering. Rain water collection in off-grid systems is one way to feed your supply. It can also allow you to keep your expenses down and even reduce your carbon footprint.
