Port Kembla 2505

Water Resource Recovery Facility (WRRF) off Military Road

Our Port Kembla WRRF was originally commissioned in the 1958 as a primary treatment plant treating both dry and wet weather flows. It consisted of screens, grit tanks, primary sedimentation tanks and sludge digestion tanks. In 1978, the facility was upgraded with a new inlet works, two primary sedimentation tanks and a sludge digestion tank. In 1993, the chemical dosing facility was provided to improve sedimentation.

The facility stores and/or treats excess stormwater during wet weather conditions. In dry weather conditions, it transfers all flow to the Wollongong WRRF.

The current treatment facility consists of screenings removal, storage tanks, primary sedimentation tanks and disinfection. Treated and disinfected flow is discharged at Red Point to the South Pacific Ocean via the ocean outfall.

The facility does not produce Biosolids on site. Settled grit and wastewater solids captured in grit tanks and primary sedimentation tanks are transferred to Wollongong WRRF after a wet weather event.

We'll be upgrading the screening and grit removal process at the WRRF. Screens trap and remove things such as food scraps, wet wipes, cotton tips and plastic (called screenings) as wastewater flows through.

Construction is currently expected to start around the third quarter of 2024. This timeframe is subject to change pending investigation results, funding approvals and weather conditions.

We'll also be upgrading lighting and flooring in switchrooms at our WRRF which is currently expected to start around the second quarter of 2024. This work will take place inside existing buildings within the facility.

We'll be replacing the variable speed drives (VSDs) at the existing wastewater pumping station (WWPS) at the WRRF off Military Road, which control the flow of energy from the electrical mains to the motors on the pumps that pump the wastewater around our network.

Construction is currently expected to start around second quarter of 2025. This timeframe is subject to change pending investigation results, funding approvals and weather conditions.
