Greywater: What is it?  Greywater is wastewater from:
  • bathtubs,

  • showers,
  • bathroom sinks,
  • washing machines,
  • dishwashers and kitchen sinks,
  • any source in your home other than toilets.

Greywater can be used in place of fresh water to irrigate (below ground) the roots of trees, shrubs, and flowers.

It's important to understand that greywater can contain harmful bacteria, viruses, and chemicals that pose a risk to public health and the environment if mishandled.
