Do farms or plantations ever use grey water?
Question Date: 2012-01-06
Answer 1:

There are many people around the world that regularly doand for growing a wide variety of plants, too. For example: UCSB actually uses reclamation water (another term for grey water) in gardens and on lawns around campus; the Department of Transportation uses grey water for the plants that line the sides of Californias highways; agricultural companies in the US that grow ornamental plants (like trees) also have been known to use grey water. People on the other side of the world, like in India for example, also sometimes use grey water for irrigating agricultural fields.

So, in short, lots of people use grey water to grow plants, and as long as people arent eating the plants, it works pretty well. But, if people are eating the plants, or parts of the plants, there can be some health issues that should be considered.

Answer 2:

I believe greywater can be used in some agriculture but not when the plants are close to being harvested!Some bad bacteria can exist in greywater so it is important to not get people sick!

Answer 3:

Here is a project idea on "Recycling greywater: Can plants tolerate it?"

recycling greywater

Answer 4:

If you have ever seen a sign in a park or city lawn that says irrigated with reclaimed water" you have seen plants that have been watered with gray water.

Gray water has already been used once, usually by a cleaning process like washing dishes or laundry or taking a shower. It has not been used in a toilet. Some soaps and soap residue could be used or broken down by the plants and may help them grow. However, if chlorine bleach was used to clean the laundry that would be harmful to the plants.

Gray water is mainly used only on non food producing plants, like grass, because legally it is still considered sewage in many parts of the country.
