Quality of grey water ...

Quality of grey water depends on the use of water. In areas of low-income people, where water availability is low, and use of water itself is low, the grey water becomes highly concentrated in terms of its impurities. One might think twice before using such grey water.
On the other hand, in areas of high-income people, where water availability is high, and the use of water is lavish, the grey water is diluted and can be reused.
