Any large-scale rainwater storage lifehacks?

This time of year has me thinking I wish I had a way to store some of the water that was pouring out of the sky this Spring.

I'm talking 1k gallons and up. Problem is when I look into buying a tank is

1. the cost of the tank alone could buy a lot of water

2. where to stick the tank so its not an eyesore and water can get into it from the gutters without a pump.

Wish my old homesite hadn't filled in their cistern for safety reasons.

Always just comes back to just paying the water bill and not hassle with rainwater collection.

Those plastic 250 gal totes with the aluminum frames are what we use at our office grid camp. They are elevated on platforms so they gravity feed the plumbing. They aren’t very pretty

I would do the same at home but I would be divorced if I did

1000 gallons of water would need to be stored underground I would think

1000 gallons won't go very far.

I could battery them up and make a 1,000gal without too much trouble. I'd have to make sure they have nasty chemicals in them before though.

And the other poster is right 1,000 really isn't all that much when talking watering outside plants.

Yeah but in a container 1000 gal water is over 4 tons. With a T

Elevating it would be out of the question so you would need to pump it to move the water anywhere.

On the totes, pipe them together at the top so that when one fills up it overflows to the second, and so on down the line

yes be careful what you buy. We got ours from a big livestock feed operation they had been filled with syrup; don’t buy or use anything that had pesticides or similar in them

True but the tank is an investment that should last for many refills.

We have a 1k gal metal tank collecting water from the pergola next to the pool. The idea was to fight pool evaporation. It's much too small to help much.

On the flip side of small, the house has a 25k gal tank. There's no city water where I live. Gravity feeds the tank and a pump provides necessary water pressure inside the house.

We have an ugly 50 gallon one on a hidden side of our house that fills from the gutter with a soaker hose that goes to my wife's flower garden. It has a hose bib to turn it off and I keep mosquito dunks in it just in case. I installed a second overflow hose at the top so it just pours out into the french drain if it's full.

This was a pet "eco" project for my wife. I don't think it does much. That isn't that much water. I am going to get rid of it after a few more seasons of her realizing it's not worth it.

But when we're having a drought and she uses it for one watering she sure lets me know how great it is

I felt that in my bones



At least you're saving money. A gallon of water here has gotten up to $0.0035/gallon. 50 x .0035 is probably like $20 or something.
