Mt Martha Water Recycling Plant Inlet Rehabilitation

The Zinfra-Jaydo-WSP (ZJW) joint venture team delivered a high risk operational renewal project extending the life of existing assets at the Mt Martha Water Recycling Plant (WRP).



Location

  • Victoria, Australia

Client

  • South East Water

Project Value

  • $1.1 million

The Mt Martha WRP was commissioned in 1978 and now treats sewage for over 75,000 people protecting the health of its communities. This pocket of the Mornington Peninsula is somewhat isolated from the larger South East Water network, making the WRP especially important. The project will enable a more sustainable water future for the growing communities in the Mornington Peninsula region.

Corrosion rehabilitation works of the inlet pipe were necessary, along with associated access structures, for the long-term operation of the plant. The technical complexity of the remediation was compounded by the high-risk nature of the required bypass pumping to enable the works to be completed whilst the plant was in full operation. The safety of our team and communities remained our top priority.

Our Role

Our team contributed to developing a detailed design, developing and implementing a complex bypass plan including redundancies as well as investigating and diagnosing concrete corrosion and challenged the status quo with new technologies of remediation techniques. The site posed many environmental considerations in protecting surrounding native trees and vegetation.
