> Investigation Work
We are currently investigating potential alignments for the pipeline and locations for three pump stations and a water storage tank.
This includes assessing environmental, heritage and community impacts in order to identify the most suitable option.
We are working closely with regulatory approval authorities such as the Department of Sustainability and Environment, local government and the North Central Catchment Management Authority to ensure all requirements are met.
A number of investigation types are required to meet these requirements:
Local vegetation and animal habitats
(flora and fauna):
botanists recording and assessing native trees, shrubs and grasses
zoologists recording fauna species and habitat
specialists mapping areas containing significant amounts of flora and fauna.
Anticipated Timing:
September 2009 to January 2010
The flora investigations seek to identify significant trees like this one, to help us consider all factors when determining the best pipeline alignment.
Natural waterways (waterway crossings)
determining the most suitable crossings required for each location (there are more than 90 although some are very small) reinstatement, and measures to minimise potential environmental impacts.
Timing:
September 2009 to November 2009.
This is now complete adn a specialist report is being assessed.
Geography and rock formations/types (geotechnical)
drilling 100 millimetre boreholes every 500 metres along roads or creeks within the area of investigation.
Anticipated Timing
November 2009 to March 2010

Topographical survey
Surveyors working on foot and using Global Positioning System equipment to gather detailed information about the terrain and surface features.
Anticipated Timing:
September 2009 to January 2010
Indigenous and European places of cultural interest (heritage assessment)
Archaeologists conducting foot surveys determine whether there are indigenous or non-indigenous sites in the investgation corridor.
Many indigenous artefacts were found during the initial investigation. This highlights the area as being culturally sensitive for the Dja Dja Wurrung community.
Further sub-surface testing will be carried out to complete a Complex Heritage Assessment Report to meet obligations under the Aboriginal Heritage Act 2006. We expect this work to start in February 2010. It will identify areas of cultural or indigenous significance to help determine the final pipeline alignment.
Anticipated Timing:
Standard Assessment -
August 2009 to December 2009
This is now complete and a report is being compiled.
Complex Assessment (sub-surface testing) –
February 2010 until completion
A sub-surface cultural heritage test site, similar to what will be occurring in the investigation area
Agricultural (easement assessment and land rehabilitation)
Assessing land conditions and farming practices for properties within the investigation corridor.
Investigations are undertaken in consultation with each landholder.
The investigation reports will assist in developing a plan for reinstatement for individual properties.
Anticipated Timing:
November 2009 to May 2010
