True but more than likely it does.

Of course it's not the same but RO waste water for some people will have a lower TDS than other peoples supply. For example if someone has a supply of 100ppm and a 4-1 waste ratio the waste water should be around 125ppm which isn't that much higher and once diluted into a highly used supply it's not much of a concern but ideally the waste water should only go to supplies that don't really matter so the user isn't forced to sacrifice water quality.
