During the next storm place a bucket under a downspout and time how long it takes to fill. Then, GRAB a RAIN-BARREL and start collecting water from your roof. Rainwater is free, contains no chlorine, and arrives to your home without the need for filtration and pumping. If you can't do some of these things at home, it may be possible for your school, business, and/or local government to look into these tips. Just ask!
Challenge: Given the size of your roof, how much rainwater can you capture during a typical storm?
