| ==Introduction== | | | topic = Greywater |
| 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. The water leaving our homes carries nutrients and value. Redirect the completely clean water we use for tasks such as showering allows us to reclaim some of that value to grow plants and recharge the water table. | | | portal = Greywater |
