While Melbourne navigates serious public safety measures to tackle COVID-19, NPE has been hard at work delivering a major wastewater bypass in Melbourne’s inner city suburbs.
The relining project is part of a major framework rehabilitation program that aims to renew aging sewer assets across Melbourne.
This particular sewer line was built in 1903 from bricks and mortar and is in some places up to 27m deep underground which made the installation all the more challenging.
On the positive side, timing with lockdown has allowed these crucial rehabilitation works to happen with minimal interruption to the local community and daily traffic movements.
To ensure the continuation of wastewater services to inner Melbourne during works, NPE installed three bypass systems and over 900m of pipeline to run a number of pumping locations.

Public safety was paramount at all times. Safety barriers were erected to allow pumping to continue and ensure local traffic could run smoothly.
NPE supplied engineered manifolds, independent line priming systems, generators, variable frequency drives (VFDs), electrical control boards and 744m of metres of 12” mine dewatering hose.
NPE bypassed flows of 250l/s on average and at peak times were pumping over 400l/s.
Regional Sales manager Doug Darville said NPE provided the bypass while the client traversed the sewer and installed the new liner.
With consideration for locals, submersible pumps, sound attenuation curtains, and silenced canopy generators were installed on location to mitigate noise.
NPE completed similar sewer rehabilitation work in Hawthorn earlier this month.
