GreytoGreen diversion system?

The greywater diversion system facilitates redirection of wastewater from the laundry and/or bathroom to a surge-tank and subsequently sub-surface irrigation system in the garden. Greywater is not taken from the kitchen as it contains fats and food particles which would prove detrimental in the garden. A surge-tank is used to collect lint and solids before the greywater enters the irrigation system.

Factors governing method of installation are:

• Size of the garden to be irrigated

• Irrigation method best suited to garden

• Distribution in the garden may be zoned if necessary to allow selective watering.

Greywater diversion systems may only be installed in single dwellings (not in townhouses or home units). 

Diverted greywater is not treated in any way and can only be used for sub-surface irrigation. 

Irrigation of lawns is not recommended when drippers are used (photo) as installation and maintenance of the sub-surface (drip) irrigation system is impractical. Use of the IWT system does allow lawn irrigation.
