Our projects in Wollongong City Council area

Fire Road No. 15

We're planning to reline the internal walls of both reservoirs in Avon and replace their roofs. These reservoirs supply water to the Illawarra water delivery system.

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

We're planning to renewal about 8.6 kilometres of the high voltage electrical supply (poles and wires) to the existing water pumping station. This pumping station provides water to the Avon reservoirs that supply water to the Illawarra water delivery system.

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

Water resource recovery facility (WRRF) off Armour Street

Our Bellambi WRRF was originally commissioned in the 1950’s as a primary treatment plant treating both dry and wet weather flows. In 2005, the Port Kembla, Bellambi and Wollongong systems through transfer of dry weather flows from all three sub systems to an amplified and upgraded facility at Wollongong for treatment, reuse and disposal. Dry weather flows are now diverted from Port Kembla to Wollongong.

A new treatment facility at Bellambi was commissioned in 2007 and consists of an internal transfer wastewater pumping station (WWPS), covered inlet screens and a storage tank, a primary treatment unit (Actiflo^TM) and ultra-violet (UV) disinfection facility. The WWPS delivers raw wastewater to Wollongong and the old disused primary treatment plant assets at the facility were decommissioned and removed in 2010.

During wet weather, additional flow overflows from the WWPS to the facility are stored in storage tanks. When they are full, the flows are treated in the treatment facility and discharged via the ocean outfall at Bellambi Point into the South Pacific Ocean. Stored raw wastewater is transferred to Wollongong via the WWPS at the end of the wet weather event until flows have subsided.

No biosolids processing is provided from the facility.

We've just finished replacing pumps at the WWPS and plan to replace the variable speed drives (VSDs) 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 2026. 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 second quarter 2024. This work will take place inside existing buildings within each of the facilities.

We'll be replacing the variable speed drives (VSDs) 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 the third quarter of 2024. This timeframe is subject to change pending investigation results, funding approvals and weather conditions.

We're also installing a new odour control unit (OCU). OCUs are installed at strategic locations to improve ventilation of the wastewater network and reduce odorous compounds to acceptable levels for atmospheric discharge. They primarily use activated carbon to filter and produce clean air.

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.

Gentles Avenue

We're currently relining the internal walls of the larger reservoir at Dapto, and replacing the roof.

Construction started in March 2022. Despite several unexpected delays, we expect to finish the project by the second quarter 2024.

3 January 2024 update.

Prince Edward Drive

We're upgrading about 195 metres of the existing water main in Prince Edward Street, Dapto.

Work started on 30 January 2023 and have temporarily finished work for now. We have some more investigation work to do, refer to the below update. After we’ve assessed the information from the investigation work and designed the upgrade for the remaining section of water main that needs to be replaced, we’ll return later in the year to do this work. We’ll write to adjacent property owners again before starting that work.

O'Briens Road

We're currently planning to reline the internal walls and replace the roof of the existing reservoir off O'Briens Road Figtree.

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

Cemetery Road and Parkes Street

We're currently relining the internal walls and replacing the roof of the larger reservoir on the corner of Cemetery Road and Parkes Street, Helensburgh and installing a new chemical dosing unit (CDU).

Construction started in April 2023 and finished at the end of March 2024. You may see us around for the next few months while we ensure the reservoir is operating as it should.

The new CDU will be installed by first quarter 2025. We will re-notify the community when this part of the work starts.

Nixon Place

We'll be upgrading electrical switchboards at our existing wastewater pumping station (WWPS) off Nixon Place, Helensburgh. The switchboards operate and control the pumps, that pump the wastewater around our network.

Construction is currently planned to start in April 2024. This timeframe is subject to change pending investigation results, funding approvals and weather conditions.

Lakeside Drive

We'll be installing a new chemical dosing unit (CDU) at our existing wastewater pumping station (WWPS) on Lakeside Drive, Kanahooka. The CDU adds chemicals into the wastewater system to help reduce odours and corrosion of our pipes.

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.
