Grey Wastewater Definition

What is Grey Water?

Grey water is household wastewater that does not come from the toilet. Grey water is therefore basically wastewater from household appliances such as showers, washing machines and kitchens. It gets its name from the gray color it gets, because it has been standing still for a while. This grey water is known for the smelly odour that this type of water causes. This smell is often caused by anaerobic decomposition and decay of organic substances such as soap scum in the water.

Bacteria for water purification

Grey water consists of a collection of bath water, shower water, washing machine water, dishwasher water and water from the sink in the kitchen. In practice this means all the water that is flushed away in the house (except for the toilets). Grey water has a very diverse composition compared to other wastewaters. This is of course due to the fact that many different systems are connected to it. This water can consist of the following substances, among others:

  • Soap residue
  • Metal particles from the pipes
  • Copper particles from the pipes
  • Cosmetics
  • Hair
  • Skin Flakes
  • Fat
  • Cleaning products
  • Food waste
  • Detergent/Dishwasher detergent
