Is it safe to reuse Grey Water ?
Yes, if used in an appropriate way. Grey Water can contain disease-causing microorganisms such as bacteria, protozoa, viruses and parasites. It may also contain fats, oils, detergents, soaps, salt, nutrients, food and hair derived from household and personal cleaning activities. These constituents can pose both health and environmental risks. However, the public health risks associated with onsite reuse of domestic Grey Water are considered low, as the source of the contamination would be from the immediate family. Other sources of transfer of pathogens around the immediate family are considered a higher risk, such as direct contact or sharing of food and utensils. Similarly, the risk of environmental damage from the careful use of Grey Water is low.
