Silvan UV Disinfection Plant

Silvan Reservoir is a critical node in Melbourne’s water supply system, providing over 50 per cent of the city’s total potable water. Silvan is located at a point where raw water from other protected catchments to the east is directed into the drinking water network to help meet demand across the wider Melbourne Water storage system.

In order to manage the inherent risk of microbial pathogens entering this waterway, this project was instigated to install a new ultraviolet (UV) disinfection plant for the Silvan Water Treatment Plant. While Silvan water processing relies primarily on chlorination for disinfection, the new plant will provide critical ultraviolet radiation for destroying any residual micro-organisms and neutralising pathogens. 

Subject to standard Melbourne Water approvals, a contract delivery strategy was developed to ensure seamless transition from design to construction and operation, with minimal impacts to stakeholders, the environment and serviceability. Touch Projects provided project management services, working closely with Melbourne Water and key stakeholders. This included the development and finalisation of a Preliminary Business Case for submission to the Melbourne Water Board.

The key aspects of this process comprise:

• Development of a contract delivery strategy. 
• Assignment of functional design documentation to the engineering services panel. 
• Tender management, including TAP setup, issue, review, assessment and tender award.
• Development of functional design, including workshops such as HAZOP and Safety in Design.
• Risk management, with sufficient engineering completed to ensure all significant cost impacts are identified and thoroughly explored, and that any delivery risks are also identified.
• Value engineering.
• Approvals management.
• Development of communications and engagement strategy.
• RANE review of the functional design to refine project costs (included within the Preliminary Business Case). 
• Development of Preliminary Business Case and associated documentation/supporting information for submission to the Melbourne Water Board.
