Grey Water Recycling

Greywater is wash water. That is, all wastewater with the exception of toilet waste and food waste derived from garbage grinders. There are significant distinctions between greywater and toilet wastewater (called "black water"). These distinctions tell us how each type of wastewater should be treated /managed and why. In the interest of public health and environmental protection, they should not be mixed together. Greywater contains far less nitrogen than black water. Nine-tenths of the nitrogen contained in combined wastewater derives from toilet wastes (i.e. from the black water). Nitrogen is one of the most serious and difficult-to-remove pollutants affecting our potential drinking water supply. Greywater contains far fewer pathogens than black water. Medical 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 recycling offers consistent water availability to overcome drought and water restrictions. Architects can design sustainable buildings that drastically reduce water use by reusing water that would otherwise be destined for the sewer. Greywater systems are a viable means of reducing the impact on our freshwater resources and therefore have become a popular option in Green Buildings. The same reduction in outgoing sewerage can be experienced when greywater is treated and recycled rather than going to the sewer. Engineers are seeking compact, all-in-one systems that allow recycling for irrigation or internal reuse in toilets and laundries.
