Grey water?

Question

I am a high school student who seeks help for a lab that I am conducting at high school. This lab is simply about how dishwashing water affects the world around us economically and environmentally. I have gathered data from a sample that I have collected from a couple of houses and tested them for salinity and pH levels. To my surprise, they weren’t high which means trying to reuse them would cost cheaper than to buy new fresh water. My question here is “Is it cheaper and to buy fresh water or to reuse the grey water by filtering it? Is it unhealthy to drink? Would we be better off not reusing it in the first place?”

Answer 1

much cheaper to use grey water, but i would reccomend only for  irrigation/garden or flush toilets as it is.

for drinking/cooking easiest system is;

slow sand filter

Answer 2

I wouldn't drink it since it has soap and any lingering diseases in it from the people eating from the plates.   I've no problem with using it to flush the toilet or watering the lawn/shrubbery with it though.

Answer 3

my Grandmother used grey water exclusively for her shrubs and ornamental trees she always had the greenest garden plants around,she had many awards from the Horticultural Society for the best in class yard

Answer 4

dont drink it, use it to flush the toilet or water some plants
