Greywater diversion devices can be either gravity or pump driven. As the purpose of greywater diversion is to water your garden, it should be treated as a garden tap, and turned on only when the garden needs watering.
In New South Wales, greywater diversion devices must have a Water Mark License.1. Older greywater diversion devices with a Plumbing Safety License2 can also legally be installed. It is illegal to connect an unlicensed greywater diversion device to your household plumbing system.
NSW Health maintains a list of licensed gravity and pumped greywater diversion devices on its website.
Pump diversion device
This diverts greywater to your garden using a surge tank and pump. Surge tanks capture the water to control the flow of greywater to your garden during sudden surges, such as emptying a bathtub. The pump distributes water through the underground irrigation system when gravity is not sufficient.
Gravity diversion device
This diverts greywater directly into your garden from areas like your washing machine outlet using gravity. Some gravity diversion systems include a surge tank while others feed straight into the subsurface irrigation system. The flow of greywater is usually activated through a tap or a switch..
