This is the fifth article in a 6 part series on Saving Water. See part 1 on measuring your tap water, part 2 on benefits of a water tank, part 3 on gutters and drains and part 4 on saving water around the house. Living in Sydney, Australia I’m acutely aware of the value of this precious resource.
When it comes to conserving water, this is the big one. As greywater comprises around three quarters of a household’s waste water, it’s well worth looking at. After all, saving water = saving money.
What is Greywater?
First, a definition.
The water you see around the house can generally be classified as one of three types -
White / fresh water : this is the clear water you drink.
Greywater / graywater : this water contains a small amount of dirt, and is water that has been previously used within the house. The water which leaves the washing machine, for example.
Blackwater : this is the waste water from the toilet.
Just remember the greywater = previously used part, and you’ll begin to see just how much of the stuff there is available.
