Yarra Valley Water


Kalkallo Creek Main Sewer Project

Yarra Valley Water has finished constructing over 4 kilometres of critical sewerage infrastructure to support the growth of communities in Melbourne’s northern growth corridor.

Project details

The new sewer is now ready to collect sewage flows from customers west of the Melbourne to Sydney rail line, between Donnybrook Road and the Merrifield Estate in Mickleham. The sewer is critical, as it is the outlet for all developments within the Urban Growth Boundary west of the Hume Freeway and north of Donnybrook Road, and connects into the Amaroo Main Sewer (which was completed in 2017).

Works occurred between May 2017 and June 2019.

Our contractor, Abergeldie Complex Infrastructure, constructed the majority of the new sewer pipe using a Micro Tunnelling Boring Machine. The project involved:

  • Building approximately 4.5 km of sewer using a Glass Reinforced Polymer pipe (GRP) at depths ranging from approximately 6 to 15 metres
  • Tunnelling underneath the Merri Creek and Hume Freeway
  • Constructing 13 new sewer manholes, ranging from 1.8m to 3.5m in diameter.
