  1. You do have a rainwater system tested, run and used yes? Mine saved my garden last year as precip was incredibly intermittent. Came in big slugs with weeks of hot dry in between. Rain barrels are simple and easy to set up and use. Pro tip: Barley Straw

  2. Just setup a 550 gallon system. Can expand it another 550 with ease.

  3. Commenter notes that collecting rain water is illegal in some states.
    Gee, I wonder if those states would be Democrat controlled.

  4. LOL

    I could float every ship in the world with the water that surrounds me.

    55 gallon drums?


  5. Is the water in the drums safe for consumption as is or do you need to filter it? If you filter do you just need a coarse filter for dirt and sediment or a purifying filter (Berkey, Katadyn, MSR, etc.?) Do you chlorinate also, and when (added to the drum or when you draw water from the drum?) Any thoughts on using water from a basement sump pit/ foundation drain? It is fairly wet due to a high water table where I live so the pit usually contains several gallons of water. In early spring or during a heavy rain the sump pump runs several times an hour. I have battery backup power charged by ac and solar for the pump so no worries about the basement flooding if we lose commercial power. It just seems like a waste of a potential source of potable water. A lot of questions to be sure, but I had planned to get water from a nearby river and purify that. Now I am looking into a less risky option that would not require venturing away from the house in uncertain times should they come.

  6. Might I point out what is suboptimal?
    1) No white barrels. That permits algae to grow in the barrel. You never know when what you are using for the garden becomes your potable water source.
    2) Paint your container. Barrels and IBCs in most cases are made of materials that degrade over time due to UV exposure.
    3) Unless its a space issue scratch drums. Go with 275/330gal IBC’s. On a $$/gal basis they are cheaper. (least in my area) Since they are in cages you can stack them to save space.
    4) Along with (3) the IBC makes purging easier using the lower drain valve. One has to tear down the setup using barrels.
    5) Filtering of water inflow. Initial inflow will also carry detritus into storage. A reasonable way to fix this is a) use a stand pipe with the outflow off the gutter at the top of the pipe. The initial rush of detritus is captured in the stand pipe for later clean out. b) A fine mesh screen over the inlet to storage.

    Like I said, have your eye to the fact you may be forced to drink that water in an emergency.

  8. I use the 275 gallon totes. Clean them with a pressure washer and then set up like in the pic. I have a metal roof and allow the rain to clean off the roof for about 15 minutes, then flip the lever on the downspout diverter. Fills up in 20 minutes with a heavy rain on a 30×18′ roof section. I keep it tightly covered with a tarp to help prevent algae growth.
