GREY WATER ! WHAT IS IT?

GREYWATER.COM  some points:

Greywater contains far less nitrogen than blackwater

Nine-tenths of the nitrogen contained in combined wastewater derives from toilet wastes (i.e., from the blackwater). Nitrogen is one of the most serious and difficult-to-remove pollutants affecting our potential drinking water supply.

Greywater contains far fewer pathogens than blackwaterMedical and public health professionals view feces as the most significant source of human pathogens. Keeping toilet wastes out of the wastewater stream dramatically reduces the danger of spreading such organisms via water.

Greywater decomposes much faster than blackwaterThe implication of the more rapid decomposition of greywater pollutants is the quicker stabilization and therefore enhanced prevention of water pollution.
