OSD’s Role

  • Project Management
  • Engineering


GWM Water was responsible for the procurement and delivery of the Wimmera Mallee Pipeline Project (WMPP) and OSD provided Engineering and Project Management support services to GWM Water for the duration of these works.

The project provided reticulated water to 7,000 rural properties and 36 towns over an area of about two million hectares. The conversion to a piped supply system saved approximately 103,000 megalitres of water typically lost through seepage and evaporation.

The system incorporated trunk and distribution pipeline works, pumping stations, water balancing storages, headworks, control systems and other ancillary works that are connected to create five separate supply zones drawing water from two sources of supply in the Grampians mountains and a sixth supply zone supplied from the Murray River

The design of the Wimmera Mallee Pipeline included:

  • Demand analysis
  • Security of Supply analysis for the pipeline system
  • Assessment of Average Environmental Flows
  • Trunk pipeline sizing
  • Storage design and sizing
  • Distribution pipeline design
  • Pump station design
  • Design of Headworks modifications
  • Assessment of power requirements
  • Assessment of geotechnical issues
  • Construction planning and staging
  • Assessment of benefits and cost of water treatment
