Well, it’s less of a rain barrel and more of a rain tote – a 250 gallon IBC tote! (IBC: intermediate bulk container). Considering that I have 1,500 square feet of contributing roof surface, I didn’t want to tinker around with 55 gallon rain barrel drums.
An IBC tote comes with very convenient plumbing connections. For example, the screw lid on the top comes with a standard two inch threaded female connection. All I had to do is connect the supply pipe to it with a two inch male schedule 40 connector – and, done!
The tote also comes with what you may call a faucet. A ball valve drain with a spout, and it is even located at the very bottom. Filling up a watering can from a regular faucet eats into your time. But this thing has a flow rate that fills a two gallon watering can in less than ten seconds. I love it.
The only thing that it didn’t have was a plumbing connection for an overflow. I solved that problem with a two inch bulkhead fitting. Because – remember – the supply pipe to a rain barrel should be the same size as the overflow. Two inch supply, two inch overflow.
To fit the two inch bulkhead fitting, I had to drill a three inch hole into a piece of vertical and flat tank wall. That got me below the maximum fill line of the tank. But a couple of elbows got me back to that 250 gallon fill line.
I also included a piece of mosquito screen across the overflow pipe. This way I keep the blood suckers from breeding in my barrel. On the supply side, the screen in the diverter-filter combo keeps the critters out.
Oh yes–and I had to connect the diverter to the rain barrel (or tote) with a couple of elbows and some two inch pipe.
Now, where did I find this beauty – this IBC tote? Craigslist! It came from an industrial cookie bakery and had originally high fructose corn syrup in it. Cost: $75. Sweet, isn’t it?
