Bondi WRRF Resilience System Investment Planning

The Bondi Water Resource Recovery Facility (WRRF) at North Bondi is Sydney Water’s oldest wastewater treatment plant, operating since December 1953. The Bondi WRRF, and the deepwater ocean outfalls installed in 1991, continue to protect our waterways and Bondi Beach. The Bondi wastewater system currently provides wastewater services to an equivalent population of 780,000 people across an area of 3,500 hectares. It services the suburbs out to Balmain, Surry Hills and the Sydney CBD through to Bronte and Bondi. 

The Bondi WRRF is Sydney’s third largest treatment plant, processing about 120 million litres of wastewater each day. It generates 100% of its electricity needs on site by co-generation, and beneficially reuses 100% of biosolids produced by supplying to agricultural markets.

Using circular economy principles in operating, the Bondi WRRF makes the most of resources in the wastewater by: 

• turning waste methane gas (biogas) into electricity which powers the operations and supplies surplus electricity back to the grid 

• producing up to 100 tonnes of biosolids (organic solids) weekly, all reused in either agriculture, composting or land rehabilitation 

• reusing up to 3.5 million litres of recycled water per day in the treatment process instead of drinking water. 

Over the next 10 years Sydney Water will invest in a program of improvement works to improve wastewater services in the Bondi wastewater system and at the Bondi WRRF. These works will provide for future growth in Sydney and continue to protect Bondi Beach, as well as ensuring that we continue to provide safe, reliable and resilient services and ensure the health and amenity of waterways.

We know that our work can sometimes have an impact on our community, and we’d like to thank everyone for their patience and understanding as we continue to upgrade Bondi WRRF.
