Got these old ice cream tubs from a local ice cream place. $1 for a dozen. I wanted to increase my rainwater storage (currently have 2 rainbarrels). Realized I could stack these guys up as much as I needed. A few drilled holes and a spout off a cracked kombucha kit and bam. Homemade rainbarrel.
This is part of a set of daisey-chained barrels so I had to keep it to 3 tubs for height reasons. All told it only adds about 8 more gallons of storage but every bit helps. You could stack as many as you wanted though, within reason.
I kept it simple but you could also add additional sealing between the bottom-lid connection to limit loss that way. I will add a few extra pictures in the comments.
Not trying to be an asshole here, but why?
What do you use the water for?
Is it worth the extra effort?
Does it save that much money?
Its for watering my garden. I water primarily with rainwater. Otherwise I have to lug my watercan to the spigot on the otherside of the house. For me, rainbarrels are a godsend. I have two 55 gallon ones in conjuction with this one.
As for effort, this took me 20 minutes to assemble. Not hard or time consuming.
For me its not about money, its about increasing my rainwater storage using what I had lying around.
We usually get hot dry summers and I have a well. Any water saved from the ground is important.
Not the OP so can’t say why they’re doing it, but in the UK at least it’s really common practice for people who grow gardens because we’ll frequently have “hosepipe bans” which means we can’t hook our hoses up to the mains to water our gardens. So, you either have stored rainwater (like OP is doing) or… a very dry crispy garden.
I don’t know how much it saves money wise, but ecologically using water from rain instead of the mains offsets the amount of water that needs to come out of treatment plants. After all, plants don’t care about water treatment really. So they don’t need the fancy drinkable tap water. They can have rainwater and that means more for the humans.
Not Op, but another reason why some people might collect rainwater is that the tap water where they live is way to hard. The mineral content is very high and for example most houseplants cannot survive on it on the long-term. My dad also used rainwater for his aquarium fish.
Yes, there are ways to filter it and make it softer, but it’s just way easier to just collect and store some rainwater.
As long you stay below 110 gallons, you should be fine legally.
Maybe some specific state, county or city, but definitely not a general rule in the US.
Most of the Western USA has some form of ordinance for it, but it applies to other arid parts of the world as well.
How do you collect water?
So my rainbarrels are daisy-chained. My primary rainbarrel (storebought) is fed directly through a little port attached to the downspout on my garage. The overflow is attached via a tube that feeds my secondary rain barrel (homemade from a plastic 55 gallon drum). What I did here is take another plastic tube from my secondary rainbarrel’s overflow and fed it through a hole on the lid of the top ice cream tub in this setup.
So for me, its an overflow barrel for my overflow barrel. Each barrel has to be slightly lower than the last so gravity can feed it from one to the other, hence why I could only stack three ice cream tubs for my setup.
If you were to make this yourself, you would want to cut a hole in the top lid large enough to feed your downspout into. Then you could add as many tubs as you wanted to get the capacity you want.
Additional pictures so you can see what I did. Its dead simple though.
One thing I forgot to add! You need at least some waterproof caulking where the lid meets the bottom of the next barrel to keep it sealed! Very important step.
Radical! I need to remember this for my garden. Finding a large water container is so difficult on a budget. But if I can make one, that’s cheaper and saves something going to landfill. hmm…
