It's amazing to me that with all of the issues that we face with our fresh-water supply, both in this immediate time of drought and as areas continue to be increasingly over-populated, that so many state and local codes forbid graywater collection and reuse.
How much would we save if we simply set houses up so that water used in our sinks and showers/tubs was automatically collected to be used to flush toilets and water plants? The technology is really very simple, and yet it's generally forbidden by the housing codes in so many areas, including in our rural county.
Why?!? I just don't get it.
