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.
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.
