GreyWater Systems Overview

When it comes to household Greywater Systems, there are two types.

  1. Greywater Recycling Systems

  2. Greywater Diversion Systems

Greywater Recycling Systems

Greywater Recycling Systems recycle greywater from the shower, bath, basins, washing machine, laundry trough and kitchen (also called sullage) to one of the following standards:

  1. 20/30 Standard: A water quality standard indicating an effluent quality of <20 mg/L BOD5 and <30 mg/L suspended solids. This standard may be recycled outdoors via surface and subsurface irrigation.

  2. 20/30/10 Standard: A water quality standard indicating an effluent quality of <20 mg/L BOD5, <30 mg/L suspended solids and E. coli <10 cfu/100 mL. This standard may be recycled outdoors via surface and subsurface irrigation.

  3. 10/10 Standard: A water quality standard indicating an effluent quality of <10 mg/L BOD5 and <10 mg/L suspended solids. This standard may be recycled outdoors via surface and subsurface irrigation.

  4. 10/10/10 Standard: A water quality standard indicating an effluent quality of <10 mg/L BOD5, <10 mg/L suspended solids and E. coli <10 cfu/100 mL. This standard may be recycled outdoors via surface and subsurface irrigation.

Greywater Diversion Systems 

Greywater Diversion Systems are designed for immediate greywater reuse. They re-use untreated greywater from the shower, bath, basins, washing machine and laundry trough. Kitchen greywater can also be used in a Greywater Diversion System, providing the kitchen greywater runs though a Grease Trap prior to entering the Greywater Diversion System. Raw kitchen wastewater which contains fats, oils and grease (FOG) should not be diverted to gardens because the FOG can reduce the availability of air to plants and harm micro-organisms.

Untreated greywater can be reused temporarily providing the Greywater Diversion System is also connected to an approved on-site wastewater treatment system or municipal sewer for times of overflow or when redirection is required in wetter months.

Untreated Greywater can be a good water resource during times of drought and water restrictions, but its reuse can carry health and environmental risks.
