Off -grid water systems
Wondering how to get water in your off-grid home?
One of the best sources of water is rain water harvesting. Rain gutters on the roof collect the runoff into a storage tank or cistern (see Oasis Design), and filtration cleans it up for domestic use. Special precautions need to be taken if used for drinking and cooking, but for bathing and cleaning, a simple slow sand filter is sufficient. There’s a good discussion group on this topic at rainwater.
But how do you pump the water from the storage tank through the home. For this we can take tips from the RV industry. Simple 12vdc pumps that run fine on solar electric are found in most RV’s. Look at this article for tips:

Now rainwater varies with seasons and climates, so you need to conserve your water usage. One of the best ways to do this is with a composting toilet. Either a nice expensive commercial unit like Biolet or Sun-Mar, or a inexpensive homebuilt unit like the Jenkins Sawdust Toilet.
It’s easy to be off the water grid as well as off the electrical grid. For more info, check out Off-grid.net.
