Greywater new ways with used water

Installing a grey water system is a great way for households to capitalise on their water usage, and as the practice gains popularity more people are discovering the advantages of re-using their water. Domestic greywater originates from non-toilet plumbing fixtures, such as the laundry, kitchen and bathroom, and grey water systems should definitely be considered in the current environmentally-conscious climate.

Greywater systems

If you are looking to upgrade to a water recycling system, the main benefits are:

• Increased savings on your water usage
• Lower water bills
• Sufficient water for all your garden needs

The two main options for greywater re-use are the Greywater Diversion Device (GDD) and the Domestic Greywater Treatment System (DGTS).

The GDD system collects and directs the untreated greywater to an underground irrigation area that is situated in the vicinity of your garden. In the event of wet weather though, when it's not needed for the gardens, the system can be switched to redirect the greywater into the sewer system. The diversion plumbing for the system is installed in the laundry and/or kitchen and acts as a buffer zone between the washing machine and the garden. The system diverts the water through a coarse screen filter to remove lint, hair and larger particles, which are caught in a surge tank. As it is untreated greywater, it is illegal for it to be stored for longer than 24 hours, so the water is released for sub-surface irrigation.

The GDD system can now be installed without council approval so long as it is carried out in accordance with the Plumbing and Drainage Code of Practice.

The DGTS differs from the GDD system in that it will collect, store and treat greywater for surface garden and lawn use and may be used in the laundry and to flush the toilet. This type of system requires council approval to install and operate, due to the treatment process involved, but the council cannot approve the installation of a manufactured DGTS unless it has been accredited by NSW Health.
