We're investing in upgrading the Bondi wastewater system and the Bondi Water Resource Recovery Facility (WRRF). These upgrades will support Sydney's future growth, protect Bondi Beach, and ensure safe and reliable services that maintain waterway health.
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 at North Bondi is our oldest wastewater treatment plant, operating since December 1953. The WRRF and the deepwater ocean outfalls installed in 1991 continue to protect our waterways and Bondi Beach. The WRRF is Sydney's third-largest water resource recovery facility, processing about 120 million litres of wastewater daily. It generates 100% of its electricity on-site through cogeneration, and beneficially reuses 100% of the biosolids produced by supplying agricultural markets.
Using circular economy principles, the Bondi WRRF makes the most of resources in the wastewater by:
The WRRF provides the community with critical wastewater services that ensure wastewater doesn't create a hazard for Sydney.
The facility is over 70 years old. It was originally designed to serve 250,000 people, but now serves an equivalent population of over 780,000. Major works are needed to improve the reliability and resilience of the assets and upgrade the ageing assets.
As we develop the master planning for the improvement program, works may include:
Over the next 10 years we will invest in improving wastewater services in the Bondi wastewater system and at the Bondi WRRF. The expected benefits of the program are:
Our planning will ensure that our wastewater system remains reliable and can continue to treat wastewater in an environmentally safe and sustainable way.
We understand our work can impact our community, and we'd like to thank everyone for their patience as we upgrade Bondi WRRF.
Work to expand the Blair Street car park within the administration site is continuing.
Many residents will be aware that two buildings within our site at Blair street were demolished as they were no longer in use and did not meet operational needs or comply with current requirements for commercial buildings. In their place, a new car park is being built on this site that will provide 15 additional parking spaces within the facility.
We’re planning to upgrade the administration building on Blair Street. The building has supported the facility for more than 20 years and is due for an upgrade.
We’re currently progressing work to expand the carpark area within our administration building located at 176–180 Blair Street, North Bondi.
As part of these works, two small buildings within the site have been demolished. These buildings were no longer in use, as they did not meet operational requirements or comply with the National Construction Code for commercial buildings. In their place, we are delivering a new street-level multi-use area and car park.
The additional carpark area will increase parking capacity for staff and visitors and help reduce the number of Sydney Water vehicles parked on surrounding streets near the Bondi Water Resource Recovery Facility.
This area will also support ongoing project operations and maintenance activities, including use as a laydown area for material storage as required.
Work on this upgrade began in January 2026. Due to project delays, works are now expected to be completed by late September 2026, weather permitting.
This work includes:
· demolition of two existing small buildings, the safe removal of building materials and the levelling of the site.
· construction of a new carpark area.
· site restoration, including landscaping.
Our work hours are - 7 am to 6 pm Monday to Friday and 8 am to 1 pm Saturday (if needed)
We’re upgrading our electrical systems at the Bondi Water Resource Recovery Facility on Blair Street, North Bondi to improve the safety for our people.
We'll soon begin work to refurbish the Ben Buckler ventilation shaft to preserve its heritage value, make it structurally safe and ensure it continues to operate efficiently. The Ben Buckler ventilation shaft is a heritage-listed operating asset that's an important part of the Bondi WRRF.
We're planning to upgrade our odour control systems (scrubbers) at the Bondi WRRF at Blair Street, North Bondi. Our wastewater system works behind the scenes to protect the environment and the health of our communities. But we need to work on it from time to time to keep things running reliably.
The Bondi WRRF started operation in 1953, providing primary treatment of wastewater collected by the Bondi Ocean Outfall System (BOOS) prior to discharge to the ocean.
Between April and June this year, we invited the community surrounding the WRRF and the wider Bondi community to give us their views on the area, the treatment facility and what living in Bondi means to them.
We're committed to minimising impacts on the community. We welcome your input so we can best understand how our improvement works might impact people who live, work and play near the Bondi WRRF.
