Question

I need an idea on how to recycle and reuse water in homes got any ideas?

Answer 1

Gray water from sinks and showers can be recycled and used for irrigating and flushing toilets that's about as far as you can go with it.The international plumbing code book walks you through all the design requirements including sanitizing and filtraion requirements for the gray water

Answer 2

I use misc rinsing water from the kitchen to feed the veggies garden. I have rain barrels, but I don't put rinse water in it; it causes putrification.
