Using recycled water safely
GMB Water operates South Australia's largest council-run wastewater treatment and recycled water scheme, aiming for 100% reuse of treated wastewater. This initiative supports environmental conservation, reduces pressure on natural water sources, and provides a secure alternative water supply for non-drinking purposes. However, using recycled water safely and responsibly is essential to protect public health and ensure compliance with local regulations.
What is recycled water used for?
Recycled water is treated to a high standard and is suitable for various non-drinking applications, including:
- Watering lawns, gardens, fruit trees, vegetables, and flowers
- Flushing toilets
- Washing cars
- Filling ornamental ponds and water features (without fish)
What not to use recycled water for
Despite its benefits, recycled water is not safe for consumption or direct contact with the body. It is important to remember that recycled water is not treated to the same standard as drinking water. Recycled Water should NOT be used for:
- Drinking (including pets)
- Cooking or rinsing food
- Baths, showers, or handwashing
- Household cleaning
- Washing clothes or using a washing machine
- Evaporative coolers or air conditioners
- Filling swimming pools or spas
- Recreational water play (e.g. under sprinklers)
Recycled water is a valuable resource and following these guidelines helps keep everyone safe while making the most of every drop.
Similarly, bore water is not safe for consumption. It is important to remember that bore water can contain chemical and microbiological hazard that are potentially harmful to health. Bore water should NOT be used for:
- Drinking (including pets)
- Cooking or rinsing food
- Watering edible plants such as vegetables or fruit trees
- Filling swimming pools or spas
Your responsibilities as a recycled water user
To ensure the safe and efficient use of recycled water, residents are expected to:
- Report leaks, bursts, or water quality issues immediately
- Provide safe access to your recycled water meter for GMB Water staff to monitor usage and billing
- Install any additional infrastructure (e.g., pumps or filters) needed to maintain flow rates, using a licensed plumber
- Use recycled water only at the designated supply address—it must not be redirected or shared with other properties
GMB Water oversight and audits
To maintain safety and compliance, the GMB Water conducts periodic audits of properties connected to the recycled water system. These audits ensure:
- No cross-connections between recycled water and drinking water systems
- Proper installation and maintenance of plumbing infrastructure
- Timely rectification of any non-compliance issues
If a cross-connection is found, the recycled water supply will be disconnected until the issue is resolved and verified through a follow-up audit.
Recycled water is a valuable resource that supports the region's environmental and community goals. By following the guidelines and using recycled water responsibly, customers can contribute to a more sustainable future while protecting public health.
