What is Greywater?
Greywater is the ‘waste’ water produced from laundry, bathroom and hand basin use. This so called ‘waste’ water is a valuable resource which can be utilised for irrigation. Greywater is defined as any domestic waste water excluding toilet waste and although it includes water produced from kitchens, kitchen greywater is generally considered as a black water as it contains high levels of greases, oils and detergents and must be treated before it can be safely used a greywater resource.
Why Use Greywater?
Greywater produces a nutrient rich water source for garden and lawn irrigation. It can also be treated for household reuse such as toilet flushing or laundry.
Reusing greywater provides a number of benefits including:
- Reducing potable water demand
- Reducing the amount of wastewater discharged into the environment
- A well-watered, healthy garden (no summer water restrictions apply!).
- Reduces household water bills.
How do I use greywater?
Greywater can be diverted directly onto your garden via a simple Greywater Diversion Device (GDD). A GDD diverts, filters and delivers water from the household source to your garden via sub surface irrigation. If you wish to use your greywater for household use, it must first be treated to a suitable quality using a Greywater Treatment System. A Greywater Treatment System is also applicable for managing entire household wastewater sources, including kitchen water, when used in conjunction with a waterless composting toilet.
