Typically speaking we can see three types of water at our places. Freshwater or tap water which is the good waste and can be used for drinking. The fresh water when utilized can be categorized into two types. The used water after washing dishes, laundering, or bathing is called grey water. Any other water that is discharged from toilet wastes or kitchen is known as the black water. The grey water usually contains soap, oil, food particles, dirt, hair etc. but can be reutilized after removal of the same. This has twofold benefits. First, it reduces the demand of fresh water required at the household for non-potable activities, and second, it minimizes the amount of wastewater entering the sewer, drains or septic systems.
