Here are a couple photos of our rain barrel, for catching rainwater and using it to water plants. Most people in the suburbs water their lawns. We do not water the grass at all, but we do water some potted flowers. Since it has been such a cool May, we have not used any rain out of the barrel yet. June proving to be pretty cool so far also.
Patsy heard a talk by an organic lawn care expert in which he said you could collect all the dandelions you chop out and soak them in a bucket of water. After they get all nasty, you can use this water for fertilizing. I did it, and luckily no one saw me, cause the neighbors would not be thrilled because of the smell. They are probably wondering who's porch has a dead skunk under it. FYI, the overflow has an internal riser, so it is not just saving half a barrel of water!
