Rain is as scarce as hen's teeth here! With the unprecedented 1" we got in Aug., the total since July 1 is 1.97". My solution is 6 35Gal. Rubbermaid trash cans across the back of my 12 x 52' mobile home. Not pretty, but those fancy (and expensive) rain barrels won't work in my situation. I tied 3 0n each side together with PVC fittings. You would be amazed at how much water you can collect from 1/4" of rain from half of that roof. I put hose spigots on the last one on each side for overflow, and run short hoses away from the house to water lawn. As of now, I have no empty barrels since last winter. Last year I ran out by Aug., but I've changed the way I water since then, so I'm good for quite awhile.
