Overview - Goldfields Superpipe

GOLDFIELDS SUPERPIPE CONTRACT Veolia has operated and maintained the 165 kilometre Goldfields Superpipe since September 2010. The Goldfields Superpipe transfers bulk raw water from the Waranga Western Channel (at Colbinabbin) and Lake Eppalock. Raw water can be transferred to Spring Gully Reservoir, Sandhurst Reservoir (servicing the Bendigo Water Treatment Plant) and White Swan Reservoir (servicing the White Swan Water Treatment Plant in Ballarat) The Goldfields Superpipe was constructed to provide water supply security for both Bendigo and Ballarat for the next 50 years. The consequences of drought, climate change and projected population growth indicated the requirement to source alternative water supplies for the Bendigo region. The Goldfields Superpipe consists of six pumping stations, three raw water balance tanks and a mini hydroelectric turbine. It has a design capacity to deliver up to 165 ML of raw water per day In 2019, the Goldfields Superpipe contract was re-negotiated and a contract renewal was executed for the continued operation and maintenance of the Goldfields Superpipe.

Performance & Contractual Compliance

CONTRACTUAL PERFORMANCE AQUA Project Management Schedule 1 of the Aqua deed consists of 36 performance standards covering water quality, quantity and system performance. Transgressions are reported to Coliban Water through Veolia’s early warning and incident reporting system. Monthly reports provide detailed performance against all contractual requirements. Monthly Toll payments are made in accordance with a formula in the Project Deed. Compliance with Performance Standards is summarized in the Tables on the following pages.

Veolia reported 100% compliance to eight of the nine performance standards related to system management in 2022/23.

Systems Management

These include Health & Safety, Quality Systems, Environment, Complaints, and Raw water acceptance, Noise and Waste Products and Water Losses.

A non-compliance was reported against Performance Standard 2: Maintenance in February 2023 relating to the failure of the Bendigo Clear water storage liner 25 parameters are monitored within the treatment processes at each of Bendigo, Castlemaine and Kyneton Water Treatment Plants to enable compliance with 18 Performance Standards to be determined.

Process Monitoring

Compliance was achieved for all performance standards.

Compliance with Performance Standard 9 – Particles at each SP5, has been suspended since January 2016, following the installation of improved turbidity meters and the re-enactment of performance standard 7a- turbidity at each SP4.

Delivery Point Monitoring

Treated water is supplied to Coliban Water through fourteen delivery points. Ten parameters are monitored at various delivery points in each of the Bendigo, Castlemaine and Kyneton systems to enable compliance with Performance Standards to be monitored.

Compliance was achieved for all performance standards.

Planned events resulted in the alleviation of several performance standards in 2022/23. The events were undertaken to provide long term water quality and security to the regions.

Activities included ● Free Chlorination at Bendigo and Castlemaine, managed in accordance to Practice note 004 ● Ongoing Free chlorination at Kyneton, managed in accordance to Practice note 005

Leak At Big Hill Interface Point BP2 INCIDENT DETAILS In September 2022, a leak from the BP2 interface point cabinet was reported to Veolia.

Investigations found the source was on the 40mm water supply pipe to the Big Hill interface point BP2. The PVC pipe was cracked and required an isolation of the interface point and Coliban's Big Hill pump station while the pipe was repaired. There was risk of low pressure at the interface during the isolation for repairs.

IMMEDIATE ACTIONS Veolia liaised with Coliban Water during the event to fill Big Hill tanks before isolation of the main, to ensure continuity of supply to customers. Leak was repaired with no interruption to customers and insignificant risk categorisation. (Incident 17665374)

Lake Eppalock Flooding In October 2022, major flooding was predicted for the Coliban and Campaspe Regions. Flood models indicated a very high risk to the Eppalock Pump Station. Veolia and the Joint Venture implemented the flood response plan to minimise damage and risk to the assets. This included the following activities: ● Relocation of motors 5 & 6 from Epplack to the Axe Creek Pump Station ● Motor 7 was disconnected and raised 600mm above the 2011 flood level, as it was not possible to safely remove it from the site ● Isolation of the power supply to the site The flooding occurred on Thursday 13th of October 2022, and substantially exceeded the January 2011 flood event, with the final flood level approximately 2.5 metres above the upper floor level. (The January 2011 flood level was approximately 600mm above the upper floor level) The flood resulted in total flooding of the Eppalock pump station and associated equipment, including the HV switch room and associated equipment, the 22 kVa transformer and associated equipment and partial flooding of the incoming HV RMU The GSP JV made a decision to handover the site to the Veolia GSP team to manage and implement the flood recovery work, including management of the flood damage insurance claim.

Major actions to date include: ● Prioritisation of the dewatering and cleaning the building and salvageable equipment ● Engaged Styles Power Solutions to restore partial power to the site to allow the commencement of testing, repairing and replacement of electrical equipment at the site ● NHP/Rockwell engaged to carry out VSD inspections ● CJ Pearce Pty Ltd engaged to inspect, clean and assess the Tamco HV switchgear ● Site inspections by CHW insurance assessors and forensic engineer ● HV inspections of the HV RMU and incoming HV kiosk

The comprehensive monitoring programs and trend analysis of water quality throughout the treatment process allowed for process control and optimization of the plant’s performance and timely mitigation controls to emerging WQ risks. Process optimization ensured treated drinking water maintained compliance with contractual and regulatory requirements.

Routine monitoring is supplemented by additional testing programs during periods of variable raw water quality and high risk events.

Raw Water Quality Risks In October 2022, Central Victoria experienced regional flooding resulting in a step change to raw water DOC, turbidity and true colour.

In February 2023, Alert Level 2 algal blooms were experienced across the region.

The risks associated with the change in raw water quality included ● plant operations risks to membranes, wash water and sludge management ● potential treated water quality risks to metals, disinfection by-products and chlorine residuals Veolia undertook process optimizations and monitoring to reduce the risk to drinking water quality and maintain operational performance and compliance to contractual requirements Coliban Water and Veolia continue to partner together to reduce the risks associated to water treatment and security to supply
