ASSET MANAGEMENT GOLDFIELDS SUPERPIPE

Maintenance Systems - Goldfields Superpipe

Eppalock Gutter Replacement

During March 2023, Veolia managed the Eppalock Pump Station gutter and downpipe replacement project

The project was quite complex, as it required the contractor (PlumbWorx Bendigo) to work at heights and above water, with all access to the gutter and flashings via a crane and work cage.

The contractor also assisted Veolia with the removal of broken glass from the flood damaged windows (whilst they were onsite with the crane and cagei work)

The project was completed on time and on budget

Pumping Trial from Colbinabbin to White Swan (May 2023)

Apumping trial from Colbinabbin to White Swan was carried out during May 2023. The trial was conducted to evaluate the operability of the pipeline and pump stations, as there had been no major pumping events since May 2015.

The trial tested the operational readiness of the Goldfields Superpipe and identified several operational issues (see below). It has also has highlighted the importance of carrying out full maintenance pumping events for both the Northern and Southern link to ensure the system is a viable “raw water” resource for Central Highlands Water and Coliban Water respectively.

Some of the issues identified follow:

● SCADAcontrol and communications issues

● Pump serviceability and lubrication

● Water quality monitoring

● Flow meter verification (with actual flows of water)
