	What is Grey Water?
		Grey water, also spelt as gray water, grey water or gray water and also known as 'sullage', is wastewater generated from processes such as washing dishes, laundry and bathing.
		From the point of view of treatment and pollution prevention, grey water decomposes much more quickly and is easier to treat and eliminate than fl water, but is still considered to be a health and pollution hazard if released into the natural environment untreated.
		Despite this, grey water is often reused for irrigation, illegally or not, in drought zones or areas hit by hose pipe bans, typically by manual bucketing.

	What is Grey Water?
		Grey water is literally the water that comes out in the wash. Not to be confused with fl water, which is wastewater that comes from the toilet and garbage disposal, grey water is the wastewater that comes from the laundry, kitchen, bathroom faucets, baths, and showers.
		Using grey water recycling and treatment systems is an important component of green building methods and practices.
		Since grey water treatment is a specialized process and requires expert installation and maintenance, it is often cost prohibitive for the average homeowner.

	Greywater - Wikipedia, the free encyclopedia
		Greywater, sometimes spelled graywater, grey water or gray water and also known as sullage, is non-industrial wastewater generated from domestic processes such as washing dishes, laundry and bathing.
		Sewage water can then be treated to limit pollution and health risks, before being returned to the environment at large.
		The level of treatment required in this case requires the water to have low or nil biochemical oxygen demand (BOD), but it is not necessary for it to be treated to the same standards as potable water.

		This will allow you to easily supply your toilets with fresh water (and prevent the contamination of your fresh water with grey water) in the event of an extended power outage or removal of the tank.
		If the tank must be removed, a drain pipe can be easily fitted between where the grey water inlet and over flow drain entered the tank, diverting your bath water to the sewer.
		The transportation of grey water to your Brac System is by gravity, so as long as the bathtub/shower/laundry drains are above the inlet of the filter housing, the system will function.
