where should grey water never be used .....? ....plz... fast​

Answer 1

hey mate!

Greywater may contain traces of dirt, food, grease, hair, and certain household cleaning products. While greywater may look “dirty,” it is a safe and even beneficial source of irrigation water in a yard. ... Greywater can also be used to irrigate vegetable plants as long as it doesn't touch edible parts of the plants.

Answer 2

Do not store greywater! ... You can store fresh water or rainwater for later use, but greywater should be used as soon as possible after it's produced. In pumped systems with a temporary surge tank greywater should not stay in it for more than 24 hours.
