Off The Grid Living Video Series
This Raven Dale cabin has all the bells and whistles and is capturing rain water from the roof, filtering it, pressurizing it for regular cold water washing and drinking and even heating it for showers with plenty of pressure. Think of an RV system running in your cabin but using rain water and you’re not cramped inside that terrible RV shower. In my opinion, this is really an ideal water system for off-grid cabins & houses, hunting camps with no running water. You need power from either batteries from solar or I suppose you could substitute a generator and 120v components but that seems wasteful so I’d go 12 volt if you can or even better do a gravity powered system if you have a hill to provide about 60 feet of head for 30psi (we have this).
Major Components you’ll need to make this 12 volt rain water collection water system in your cabin.
- Metal roof, gutter
- Rain Storage Tank
- RV propane water heater or similar on demand unit. Most RV units heat 6 gallon tanks
- Plumbing supply lines to whatever fixtures you want, shower, sink, toilet. He’s using PEX or a similar flexible plastic pipe system. A drain at the lowest point in supply lines for winterizing is very important for a seasonal used cabin to prevent frozen pipes.
He’s got his pipes on the outside of the building and that may be fine for his climate but everyone’s system should be designed to fit their climate.
What would your ideal system entail? Please leave a comment below. I’d love to hear about your project.
