Parasyn was engaged by the BFHI Joint Venture, a partnership between BecaHunterH2O, Fulton Hogan and Interflow, to deliver the PLC and SCADA controls package for the Mount Martha MSB Replacement and Generator Upgrade. The project sits within South East Water's broader capital works program to renew critical water infrastructure across Melbourne's south east, and covers the controls supporting a full main switchboard (MSB) replacement and generator upgrade at the Mount Martha Water Recycling Plant.
Rather than redeveloping the plant's control system from scratch, Parasyn proposed a risk-based, structured code migration, converting the plant's existing standard code to the current UDFB standard while preserving the automatic and sequencing logic that keeps the plant running day to day. It's a lower-risk path than a full rebuild, chosen to protect plant continuity through the eventual cutover and leave South East Water with a more maintainable asset.
The project has now reached its Factory Acceptance Testing (FAT) stage, with FAT conducted and signed off with South East Water in early September 2026. The team is moving into final testing and site cutover, targeting completion in mid-2027.
“Mount Martha is exactly the kind of project we like to be trusted with. It's a live, critical asset, so a full rebuild was never the responsible option, we needed an approach that protected the plant through the transition rather than putting it at risk for the sake of a cleaner slate. Reaching FAT with South East Water is a good marker that the approach is paying off, and we're looking forward to carrying that same discipline through commissioning with the team at BFHI.”
Projects like Mount Martha reflect the role Parasyn plays across the industry: a specialist OT and controls partner that engineering, procurement and construction (EPC) contractors and joint ventures can bring in to deliver the parts of a project that demand deep SCADA, PLC and industrial automation expertise, executed to the client's standards and integrated cleanly into the wider program of works.
