On mine there are a couple of raised rings that go around the circumference of the barrel and sort of divide it into thirds. I was thinking of using those as cutting guides. That would give me around 18 gallon capacity. Not that 18 gallon container would be much easier to tip over than a 25 gallon container, but it would be a bit lighter. I could also add a couple of handles on them using the middle section.

Kris, Let's see if somebody will start a new thread - but you can read all about the SBC product at the link below. What do you use to catch rainwater off your shed? Are you really limited to shed roof for runoff? The ground is the best source of rainwater catchment, particularly if you have a low-lying area of ground that holds water after a rain event. Digging a hole in the ground and installing a liner of any type is still the most efficient and cost-effective method. Robert Here is a link that might be useful: Quikwall SBC Info

Just wanted you to know that my Water system work fantastic last summer. There were no leaks, no mosquitos, and really no ugly green water. The original lids of the trash cans were no help because the weight of the water in the cans would stretch out the barrels and the lids wouldn't snap on. I ended up putting a patio stone on them. I'll have to try some new type of lids this summer. The valves were just perfect. Big enough not to wait long for the 2 gallon watering can to fill up. In fact the water flowed out faster than the water from my house spiquet. I reconnected the gutter downspout at the end of summer and turned the drums on their sides so that they wouldn't fill up with snow during the winter. The bottom connector even worked like a charm. It kept both cans filled at the same height all summer. I always wondered why you will put the attachment to the other can at the top... maybe that is helpful if you dip the water out, but with the bottom valves I eliminated that. Got a new digital camera, so I'll post some pics of what this thing looks like in the spring. All in all, final grade A-

Tried all the recycling places in the area, with no luck. Any other ideas out there? I was told food producers. The problem I am running into is that many are not listed, and I only know of a few. Bottlers are supposed to be a good thing to try too, but again, I don't know of any around. Thanks for the lead though.
