Water Collection and Catchment

Once we had metal roofing on all of our buildings, adding water catchment jumped way up the list. We have a creek and a spring on the property, but wanted an option that kept us from having to lug water for the animals and drag hoses across the drive for the garden. It also let us position water storage where we wanted it.

The first one to go up is by the barn, to provide water for the animals and water for the garden.

I got 250 gallon IBC totes from a winery, that way I knew what was in them and knew they were safe for potable water.

I wanted to get them up off the ground to give them some head pressure to hopefully be able to run 100’-150’ of garden hose for the garden. I decided a 4’ rack combined with the natural several feet of elevation change should do it, plus I was worried going higher would be more unstable.

I thought about buying it out of treated lumber, but I can’t swallow the current prices of lumber, so I decided to build it out of steel. More expensive than the lumber, but a whole lot more durable too.

I built the fram for the tote to sit on the same size as the tote frame, with tabs to keep it from being able to slide off. Think it ended up being 38”x46”.

First thing I did was test my welds, it’s been a while since I’ve run my welder since there was no electric in the barn until a couple months ago, an I just wired in the 220 this weekend. It held the tractor up, and that was with only two sides of the tube welded.

The frame, made from 1-1/2” square tube with a 3/16” wall:

Squaring the legs was obviously pretty important since it will have 2000lb of water plus the weight of the tote on it, and doing it with no extra hands was tough.

I used 3/8”x3” flat bar for the tabs and for diagonal bracing for the legs. I used 5/8”x10” flat bar to make pads for the feet because I didn’t want to set it in the ground, I wanted to keep it mobile if I chose. This is all rigged up to move with the tractor, I’d guess it weighs about 220-250lb.

The spot where were locating it is on a bit of a hill, so I had to dig down in one side and build up on another. I put down a couple inches of gravel to keep it from getting muddy and to keep it from sinking. I could only get it to about 10’ from its final location with the tractor because the ground was too soft, so getting it to final position was a bit of a wrestling match for one guy. Wrestling the tote up on the stand was even more so.

I used a cam-lock fitting with some PVC adapters to get it to a brass hose bib. I have a drinking water hose from and RV supplier for potable water, couple hundred feet of rubber hose for watering the garden.

Welcome any thoughts and opinions, ways to improve, tips from y’all’s setups.

Love to see some setups from others here, I’d like to have 4 total systems for myself with each being one of those totes.

Fantastic post, the kind I love to see on OTGF! If I could give 2"likes" I would!

The using gravity is a great idea. Unfortunately, my catchment tanks are at the lowest point of my house, but I do have 2 tanks uphill that provide some decent head. It takes a pump to fill them, though.

My setup here.

Thanks!!

That tote is catching one side of the garage roof, I still need to tie the other side in, but it took a part I didn’t have on hand. I’ll get some pics of tie ins tomorrow.

One thing I have not yet figured out is how I’m going to handle overflow. It won’t take long to fill 250 gallons from a 26x26 garage roof.

One tip I can give you is that if you paint your tote or wrap it in plastic, or some other way to keep it in the dark, you will get a lot less bacterial/algae growth in your tanks.
I’m going to close in everything with the same metal from my roof, except the bottom portion (just the stand part) of the front that you see in the pic. I’m leaving it open to use as tool storage for the garden. It’ll be good for keep hoes, rakes, shovels etc since it’s right next to The garden.

So I finally got the plumbing done and have the pump in place. Fabricated a mount for the pump that still lets it be removable, and plumbed it in with two compression fittings on the inlet and outlet sides so that the pump can be completely removed without cutting pipe. All lines, and the pump, will be heat taped, but it still leaves the option of removing the pump for the winter.

Tested it with a hose on the spigot, and there is just as much water pressure as at the house.

Very nice work, Bacash!

One thing that I am considering adding to my setup is some kind of sight tube to see how much water is in the totes.

Edit: Details on the pump? 12v? 120V? mfg? etc.?
Ahh, good thought on the sight tube, or something similar. I plan to put roofing metal over mine to help inhibit algae growth, so that would be useful.

Pump is a 12V Seaflo rated at 3.5gpm, made as an RV water pump for the potable water system. It's nice because it has a pressure switch, so once it pressurizes the line, it shuts off. It seems very well built, and had no issues with setup or testing. It's pretty reasonably priced at $60ish on Amazon, reasonable enough that I bought an second the other day as a back up.

Finally got some solar hooked up to a charge controller and the battery that I’ve been using to run the pump. Everything is temporarily attached, it’s currently in proof of concept phase, so everything will be neatly run and inside the building behind it when done.

one lil suggestion, at all points where you added braceing to your stand, think about spreading the weight by adding gussets. that is a lot of weight when full.

I thought I had pics up here of my previous catch basin from the old house. Must have been the old site. Anyhow, I found a pool liner for a 8x20 lap pool with 4" sides. About 250$ iirc. Then I dug a trench of appropriate size and made a "box" for the liner from green live oak. Any wood will probably work with the evidence I've gathered from oak Island. Keep it wet and away from air and it will last hundreds of years.

I made a roof from an old trailer I had, welded the axles together end to end at about 12" wide so I could roll the entire roof on and off. Let the air out of tires and it "seals" the lid. Got some used roof metal and made it wide enough so ground water runoff couldn't enter. AFAIK the new people still use it for the garden.

I'll only collect water from a metal roof, not asphalt.

Overflow was mentioned, I just put a 6" pipe from the basin over to the ditch. States with 4" and the runoff from a 22x40 roof overwhelmed the smaller pipe.

I'll find pics over the weekend or just drive over there.
