# Black water is water that has come into contact with human or animal excreta, and waste from food preparation which is commonly referred to as sewage (World Plumbing Council Working Group 2008).
# Also, source-separated wastewater from toilets, containing faeces, urine and flushing water (WHO 2006).

==Explanation==
Black water contains a high level of microbial pathogen contamination and is a high risk
water source. Black water cannot be reused without a high degree of treatment and
management control. The most frequent test for contamination is for E. coli (New Zealand
Ministry of Health 2007).

Black water is a high risk source of water for reuse. It requires a high level of
management control to ensure the protection of public health, the environmental health
and education material for the plumbing industry, end users and the general public (New
Zealand 2007).

Pathogenic contamination of foods can be caused by use of black water for irrigation or
fertilization on food crops. Contamination of drinking water, washing water, or recreational
water by untreated black water will contribute human or animal pathogens (World
Plumbing Council 2008).

==Example==
Bodily wastes and the associated water from waste disposal facilities are termed black
water. This water can contain pathogenic bacteria and other disease-causing organisms
that make the water unsafe for untreated use in capacities that would create direct human
exposure.Problems can be caused by use of black water on food crops or mixing untreated
black water with water used for drinking, washing, or recreation. Such uses can expose
humans and livestock to pathogens (WHO 2006).
