~ Murray Valley Number 1 - Decommissioning works complete
7 June 2007
G-MW, in partnership with the Moira Shire Council, have recently constructed a new pump station and
pipeline from the Murray River downstream of Cobram, which has allowed the decommissioning of the
Number 1 channel through Cobram township. The new pump station has been successfully operating this
season and has supplied almost 6,000 ML to the customers on the Number 1 channel downstream of
Cobram. The pump station has been designed to operate under River Murray floods, but due to extremely
tight timelines and predicted low river levels, flood commissioning was deferred. This commissioning has
now been successfully completed. Some subsidence occurred during this commissioning, and the
Contractor will return to rectify shortly.
The major task associated with the decommissioning was the Town Siphon. The siphon is a 375m long cast
insitu 1200mm nominal diameter concrete pipe that runs under three roads (including the main road to
Barooga), St Joseph's Primary School, 4 house lots and the Cobram hospital, surfacing in the middle of the
hospital carpark. Over 470 cubic metres of low strength grout was used to fill the pipeline. This task was
managed by Mark Poole (ATS- Technical Services) with support from Dave Darby (Murray Valley) and a
number of Murray Valley Staff who undertook the supervision of concrete trucks, traffic management and
excavation and refill of the inspection/fill points along the pipeline.
The final structure abandonment on Campbell Rd (see photo) was completed at the end of April 2007. The
end structures were removed, two water supply pipelines were relocated and pipes filled with grout. Three
other road culverts have been abandoned·and 3km of channel has been pushed in and graded.

~ Shepparton Modernisation Project
Under G-MW's Wateright2020 quest to save 400,000ML the $188M Shepparton Modernisation project was
born. The Shepparton Modernisation project involves a number of water saving measures including channel
automation, pressure pipelines, gravity pipelines, improved metering and targeted maintenance. The project
business case is being prepared by P&E (Water Savings Unit) and is currently being finalised with DSE
while implementation of the works will be managed by ATS (Major Projects Unit).
In May 2007 the Minister for Water announced $37.5M to commence the project in 2007 while the finer
details of the business case are being negotiated between G-MW/DSE. Works are scheduled to commence
late into the 2007 winter maintenance period and involve automating channel control structures along the
East Goulburn Main (EGM). Extensive planning has been undertaken by Major Projects, in partnership with
the Shepparton Area, Technical Services, the Reconfiguration Planning team and principal contractor
Rubicon, to ensure that G-MW could deliver on the Government's May commitment that works would
commence in 2007.
