Client: Westernport Water
Role: Commissioning Manager
As client side Commissioning Manager on behalf of Westernport Water, Janson Projects successfully oversaw the upgrade of the Cowes Wastewater Treatment Plant (WWTP) for Westernport Region Water Corporation, which provides water and wastewater services to approximately 19,000 properties on Phillip Island. The project enhanced the plant's capacity to handle the forecasted BOD and hydraulic demands through 2046, with new infrastructure designed to meet projected requirements up to 2076.
The project scope included:
Replacing one of the existing aerators
Constructing a new clarifier with provisions for a future fourth clarifier
Building a new RAS pump station to service the existing two clarifiers, the new third clarifier, and a planned fourth unit
Installing a scum pump station to manage scum and floating plastics from clarifier surfaces
Additional work incorporated into the project included:
Screening mixed liquor before it enters the clarifiers
Modifying the mixed liquor pump station to accommodate future flows
Developing piping and instrumentation diagrams for the entire plant, excluding the recycled water system
Janson Projects’ expertise ensured the seamless delivery of this vital infrastructure upgrade, supporting the region’s long-term wastewater management needs.
