Green Livin What is Graywater?
“waste water that does not contain sewage or fecal contamination (such as from the shower) and can be reused for irrigation after filtration.”
Graywater Central, from Oasis Design, defines it in a slightly different manner:
“Any water that has been used in the home, except water from toilets, is called graywater. Dish, shower, sink, and laundry water comprise 50-80% of residential waste water. This may be reused for other purposes, especially landscape irrigation.”
As part of ways to save the planet, we recommend the re-use of water, but what are the benefits of using graywater? Again, Graywater Central lists a few:
Lower fresh water use
Less strain on failing septic tank or treatment plant
Graywater treatment in topsoil is highly effective
Ability to build in areas unsuitable for conventional treatment
Less energy and chemical use
Groundwater recharge
Plant growth
Reclamation of otherwise wasted nutrients
Greywater.com is a great source of information that provides step-by-step information on how to set up an irrigation system, how much water you could save, what to do about pollutants and so on.
