Introduction
Greywater, sometimes also spelled as graywater, grey water or gray water, is all of the effluent water from a household, except that which has touched a significant amount of poop, i.e. all water flowing out of a house except that from the toilets. In addition, if greywater is held for too long (>24 hours in temperate climates), it will become blackwater.[verification needed]
The water leaving our homes carries nutrients and value. It may also contain pathogens, and/or harsh chemicals and care should be taken with it; however, it is not a great risk compared to blackwater (sewage).
Redirecting the water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. It may be necessary to choose our soaps and detergents more carefully, if we use the greywater for watering and fertilizing plants.
