Okay, buckle in, folks, this is where things get a little… less than clean.
What separates black water from gray water? How about white water?
Simply put, black water contains fecal matter. Gray water is, essentially, all other household waste (or waste from a commercial property or facility) that does not contain fecal matter.
Black water, as you might imagine, contains harmful materials. It should be pumped by professionals with the right gear and experience.
Grey water can, if you wish, be recycled. Or we can pump that as well.
White water is clean drinking water.
