You can do a little bit of water recycling in your own home to help reduce your water footprint. I do a couple of things to save on water usage, and even though they probably only make a tiny dent in the community’s water footprint as a whole, they make a difference in my household.
If anyone in the house leaves a partially full glass of water lying around, then I never dump it out. I put the water into the recycling bucket, and once I have enough water there, I boil it and put vegetables in the pot to cook. Once the water is boiling, the germs are removed, so it should be safe for everyone to consume.
Also, I recycle my bath water in the garden. I scoop it up in buckets and take it outside to use for watering the plants. They don’t care if it has some dead skin in it. It nourishes them just as well as fresh hose water.
