What an interesting idea via Lifehacker.
NewMexiKen’s neighbor collects water from the canales (known elsewhere as gutters) to use to water his plants. I find that pretty impressive. I mostly use the water from my roof to splash down and wash top soil into the street.
the problem with water salvage is that water stored for any length of time greater than 24 hours begins to have a foul odor. After a while it won’t smell any better than what’s being flushed.
