Rain Barrels and Sand Filters for water storage
We don’t have any well or running water on the property but being on the Olympic Peninsula in Washington State, we have a ton of …. You guessed it. Rain!
We already catch rain off half of the shed roof into one of two 55 gallon barrels we have. It’s connected to a garden hose and then a hose spigot. Used only for washing it works great for us now but I’d like to connect the barrels like the guy in the video did with a PVC manifold. That would give us more pressure and get us through a long summer drought.
I wanna build this:
The master plan is to pump the water in the 2 barrels up to our 650 gallon storage tank on the hill above our property. We’d use a 12 volt utility pump to empty a barrel when the sun is out then let the batteries charge again. If we did it a little everyday we’d have plenty of water in the tank on the hill that could then provide tons of pressure for our cabin. I can imagine some pressure to spray pots off and even take a shower in the summer would be great. Also having some pressure to spray out of a hose would come in handy for fire fighting if we ever had a fire get out of control.
Here is some bad photos of our system now. The rock filter you see stops most of the pine needles, but a screen would be better.
Then someday if we want to drink the water, maybe we’ll make a sand filter. Here’s a great video show you how they work. Towards the end they show it can be backwashed, which you wouldn’t normally do but it’s a good illustration of the concept. Sand filters use microbes to clean the water.
