Here’s the rainwater cistern from dream to (almost) done! Built with earthbags and a custom liner. This cistern, made of earthbags like the rest of the house, will be the primary source of water for the house. We’ll collect rainwater from the roofs of the house and the RV shelter (both of which will be metal). The water will be used for washing, bathing, and–after running through multiple stages of filtration–drinking. For more details visit Lily Ann Fouts blog.
