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.
Whats the logic?
The areas are fairly arid, to the point where the upstream cities could cut off water from downstream cities by just withholding enough. Therefore, water rights became a thing, with the order of rights going from oldest to newest.
Further agreements were made, like the Colorado River Compact, which negotiated minimum water supplies between the different American states and later included parts of Mexico.
Ah ok so the idea is if youre capturing it, it isnt running off into the river system. That does make sense.
Yeah, and the Colorado & Rio Grande rivers are at least river basins with negotiated agreements. Other parts of the world don't have these agreements and these disagreements could cause wars in the near future.
It also goes into the ground, and catching the rain prevents it from refilling ground water reserves. The issue is some people (Nestlé) could effectively cause a water scarcity issue and sell the water they're taking, when it should belong to everyone.
