Grey Water

Grey Water is a non-industrial wastewater generated from domestic processes such as dish washing, laundry and bathing. It comprises 50-80% of residential wastewater. Wastewater is generated from all of the house's sanitation equipment except for the toilets, water from the toilet is considered blackwater.

There are three ways of reusing greywater:

• Manual bucketing – small quantities of greywater are captured in a bucket for re-use outside on gardens or lawns. No council approval required.
• Diversion – greywater diversion devices redirect greywater for use outside the home on gardens or lawns using sub-surface irrigation. No council approval required under certain conditions. Needs a plumber to install.
• Treatment – greywater treatment systems for reuse inside the home (e.g., toilet flushing, washing machine) as well as outside on gardens or lawns. Council approval is required. Needs a plumber to install.
