I keep reading that water is getting to be in short supply although it rains frequently. One company I found has a solution and that is to collect rain water in new fangled rain barrels. This was often done in the good old days.
Here is a source of various kinds of rain barrels............whats missing in my mind is how to set up a way to use the water that would make sense. I guess you could use slow drip system in planted beds near the barrel???
