The water you use in the sink to brush your teeth, rinse your vegetables, etc. Most think gray water is additionally clothes washing water and shower water. To me, there are 2 stages of gray water. To most, it's anything NOT flushed thru the toilet.
A lot of hotels and other large commercial enterprises clean the water from sinks and use it to water the grounds or in heating systems.
