Yarra Valley Water has finished upgrading the Mandalay Sewer Pump Station at Beveridge, on Melbourne’s northern fringe, lifting capacity in the sewer network that serves one of Victoria’s fastest-filling housing corridors. The work was the final stage of the utility’s Rankin Street Sewer Project, delivered with civil contractor Jaydo.
The completion was reported by Utility Magazine, which said the upgrade is designed to carry both current and future demand as development spreads across Beveridge.
Yarra Valley Water Deputy General Manager Asset Delivery and Care Simon Willis said the investment was needed to keep pace.
“As Beveridge continues to grow, investing in critical sewerage infrastructure is essential to ensure we can continue providing safe, reliable services for our customers,” he said.
The last stage wasn’t pipelaying, it was sparkies and sensors
Most of a sewer project is trench, pipe and backfill. This one finished the other way around.
Jaydo developed an in-house electrical design for the station and staged the pump operations to work inside the limits of the existing power supply, Utility Magazine reported. That is licensed electrical work on live utility plant, not a plumbing job, and fixed electrical installation work requires a licensed electrician in every state and territory. There’s no version of it a handy operator can knock over on a Saturday.
The crew also ran electric bypass pumps instead of the usual diesel units during construction, and powered the temporary site offices off mains rather than generators to keep the noise down for neighbours outside standard working hours.
Bypass pumping is the part of a live pump station upgrade that keeps everyone awake. You’re carrying the whole incoming flow around the works while the station itself is off. Going electric on a site the contractor had already flagged as power-constrained is the reason the in-house electrical design mattered so much: no temporary supply, no bypass, no shutdown window.
Permanent sewer level sensors went in at the station to give early warning of potential spills and improve network monitoring. That’s instrumentation and control work sitting alongside the mechanical fitout, and it’s increasingly where the hours are on utility jobs.
Willis said the delivery approach was built around the neighbours.
“Completing this upgrade means the network is ready to support current and future demand, while the innovative delivery approach helped minimise impacts on nearby residents.”
Fire danger cost the program three reschedules
Planned shutdowns were pushed back three separate times to avoid periods of extreme fire danger, according to the Utility Magazine report.
Anyone who’s worked a greenfield site in Victoria’s north knows the drill. Dry grass, plant, hot works and a forecast that turns at 4pm. Three reschedules on a shutdown means three rounds of crew mobilisation, bypass hire and traffic management booked and unbooked. It’s a program risk that doesn’t show up in a tender price but shows up in the calendar every summer.
Five kilometres of pipe fed this station
The pump station upgrade caps a much bigger civil job. Yarra Valley Water’s own Rankin Street project page records a 1,500-metre micro-tunnelled section with shafts sunk every 100 metres, plus a further section of roughly 3,300 metres built using a combination of methods including open-cut trenching.
Do the sums on the shaft spacing, and the tunnelled leg alone accounts for about 15 shafts. Shafts are where the labour goes on a micro-tunnelled sewer: sinking, shoring, dewatering, pipe jacking crews and the confined-space regime that comes with all of it. The open-cut leg is a different trade mix again, more excavator, pipelayer and reinstatement.
The alignment runs from Patterson Road to the Lockerbie Main Sewer, east of the Melbourne to Sydney rail line along Rankin Street. That trunk main is nine kilometres long with 14 branch connection points serving Donnybrook, Beveridge and Lockerbie, and Jaydo worked on it too, alongside Broadspectrum, using both open-cut and tunnelling in Beveridge. Same catchment, same contractor, different decade of growth.
Sewer capacity is what decides how many lots get built
Here’s why a pump station matters to a chippy who’s never seen one. In growth corridors, sewer delivery is the brake on subdivision approvals, not demand.
The Victorian Planning Authority’s Beveridge North West servicing assessment, dated March 2014, capped development in the precinct at a maximum of 3,000 lots until the ultimate gravity sewer outfall was delivered, and referenced a 4,000-lot limit across the wider Beveridge and Wallan area beyond which additional assets had to be built early. Those figures are more than a decade old and may have been superseded, but they show the mechanism: pipes and pump stations first, titles second, slabs third.
The same 2014 document flagged that the site couldn’t be serviced directly from adjacent existing electricity assets, which lines up neatly with the power constraints Jaydo had to design around at Mandalay.
Mandalay is one station in a wider northern sewerage program the utility lists on its works pages, alongside the Wallan Sewer Project, the Hume and Moreland Sewer Improvement Project and the Wollert Recycled Water Project. For contractors chasing utility work rather than housing work, that’s the pipeline worth watching. Trunk sewer capability in this corridor has stayed with a small number of specialist crews for years, and the jobs keep landing in the same postcodes.
If you’re a residential builder in Mitchell Shire, the practical question is which stage of which sewer your next estate hangs off, because that timing sets when your slabs get poured, not the sales office.
Frequently asked questions
Where is the Mandalay Sewer Pump Station and who upgraded it?
It’s at Beveridge, on Melbourne’s northern fringe. Yarra Valley Water delivered the upgrade with civil contractor Jaydo as the final stage of the Rankin Street Sewer Project.
Why were the planned shutdowns delayed?
Planned shutdowns were pushed back three separate times to avoid periods of extreme fire danger, according to Utility Magazine.
Does sewer capacity really limit how many houses get built?
In growth corridors, sewer delivery is the brake on subdivision approvals. The Victorian Planning Authority’s March 2014 servicing assessment capped Beveridge North West at a maximum of 3,000 lots until the ultimate gravity sewer outfall was delivered, though those figures are more than a decade old and may have been superseded.
Can electrical work on a pump station be done by anyone on site?
No. Fixed electrical installation work requires a licensed electrician in every state and territory, and the Mandalay job involved electrical design and staged pump operations on live utility plant.
