Answer 1

What is grey water?
Any water that has been used in the home, except water from toilets, is called grey water. Dish, shower, sink, and laundry water comprise 50-80% of residential "waste" water. This may be reused for other purposes, especially landscape irrigation.

Why use grey water?
It's a waste to irrigate with great quantities of drinking water when plants thrive on used water containing small bits of compost. Unlike a lot of ecological stopgap measures, grey water reuse is a part of the fundamental solution to many ecological problems and will probably remain essentially unchanged in the distant future. The benefits of grey water recycling include:

Lower fresh water use
Less strain on failing septic tank or treatment plant
Grey water treatment in topsoil is highly effective
Ability to build in areas unsuitable for conventional treatment
Less energy and chemical use
Groundwater recharge
Plant growth
Reclamation of otherwise wasted nutrients

Wastewater is categorised as either grey water or black water.

Grey water is made up of the wastewater from our showers, baths, spas, hand basins, laundry tubs, washing machines, dishwashers and kitchen sinks. (It doesn't include water from toilets.) Used appropriately, you can water your garden with grey water and save around 400 litres of fresh water each day.

Grey water can be diverted to your garden through direct diversion or a domestic grey water treatment system (DGTS). A DGTS will produce higher quality grey water to use in the garden and possibly your toilet or washing machine.

Black water is made up of the wastewater from our toilets, urinals and bidets. It is grossly contaminated by human excrement and requires a detailed treatment process such as a composting toilet before it is suitable to use in the garden.

NSW Health has guidelines that you must follow when treating black water, however it is not commonly used throughout Sydney.

How much wastewater do households produce?The amount of wastewater generated by any household varies greatly according to the number of people, their age and lifestyle. Sydney Water estimates that an average household (3.5 people) produces 586 litres of wastewater each day.

How much wastewater can be used as grey water?Approximately 61 per cent of the total wastewater produced by an average household can be used as grey water. Kitchen wastewater is not usually included in this amount.
