Grey water is great water!

Abstract

Water Kidz No matter how conscientious we are – everyone has to use water, and not just for drinking purposes! We also need water for washing, cooking, and doing the laundry. The upside is that much of this water can be reused. It is estimated that as much as 60% of the wastewater produced by an average household can be reused as greywater. The water left over in a basin, and from showering, bathing, and laundry is known as greywater. (Greywater does not include water that has come into contact with poo, such as toilet water and from washing diapers – this is known as blackwater, and is not safe for reuse). The problem is that our modern sewerage systems do not distinguish between black water (which needs to be treated) and greywater, which can be reused. While greywater or slightly used water might seems dirty – it might contain traces of food, dirt, grease or cleaning products – it can still be used for various things.
