RoadWarrier,
I added a faucet just above the bottom of a 55 gallon drum so I could add a hose to it to water the dam before it had grass and other remote trees away from our camp. The flowrate I got was less then anticipated but still was functional. I suppose this is similar, but costs much less, than one of those "rain barrels" I've seen on the internet.
