Grey Water Technology

What is Greywater?

Greywater is the wastewater produced from  the hand basin, shower, bath, washing machine  and laundry tub. It is not the water from the  toilet, kitchen sink or dishwasher as this water  is generally too high in grease and oil to be re-used successfully.

N.B. If a greywater treatment system is being used rather than a Greywater Diversion Device, the waste water from the kitchen can be included.

 

Greywater for irrigation

Greywater irrigation has long been practiced in areas with a limited water supply. However, proper precautions for its use have not always been in place. This has posed a problem for health officials, who believe there is no correct method for managing greywater to both balance user water needs with public safety considerations. While the engineering of these systems is still a relatively new technology, it is one that is progressing rapidly. Greywater systems can now meet both environmental and waste management requirements, while safely utilising the nutrient content in the effluent.

The options for safely using greywater as a source for irrigation are many and diverse.

There are two types of greywater systems for the domestic market that both require local government approval and state government guidelines for installation:

  • Diversion Systems are either gravity or pumped.
  • Treatment systems which upgrade water quality in the process and provide more flexibility in terms of re-use applications

N.B. All grey water diversion systems MUST use by law a sub-surface irrigation system, such as drip irrigation.
