Was over at my brother's house a month ago and saw that he had some rain barrels set up. I had a couple of extra 55 gallon plastic food grade drums laying around so I thought I would give it a try (attached to downspouts to catch runoff). This got me looking around the internet and youtube. There are some amazing systems that people have built to capture rain. Finally put them together a couple weeks ago and watched them sit empty. Lots of hot weather and no rain. This morning I was awakened by thunder. Got up and ran out to check the barrels. Yup, raining like crazy. Both were filled in 10 minutes and overflowed after that. I have five downspouts on my house and only two attached to barrels. It rained hard for about 45 minutes and I am sure I could have filled them up many times over. That of course got me to thinking about not only adding some more barrels but thinking about what you can use the water for during an emergency. Certainly you could wash with it. I suppose if you ran the water through an inline filter you could even drink it. Rain water is probably a lot cleaner than other natural sources. So does anyone else have a system set up?
