WC Fields said about water, "Water... never drink it. Fish (fornicate) in it." Companies who sell bottled water don't make water, they make plastic bottles... not to mention the large ones are buying up water rights. In one house I lived in, I decided to capture the condensation from our AC unit and use that water to water our plants. On really warm, humid days, I could fill up a 30 gallon drum in 48 hours.
