> Investigation Work

We have investigated potential alignments for the pipeline and locations for two 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.

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.

Geography and rock formations/types (geotechnical)

drilling 100 millimetre boreholes every 500 metres along roads or creeks within the area of investigation.

Topographical survey

Surveyors working on foot and using Global Positioning System equipment to gather detailed information about the terrain and surface features.

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, highlighting the area as being culturally sensitive for the Dja Dja Wurrung community. 

The results of the standard assessment identified that an approved Cultural Heritage Management Plan (CHMP) would be required under the Aboriginal Heritage Act 2006 for this project.

The CHMP was developed using the information from the initial field work together with sub-surface testing and discussions with the Dja Dja Wurrung field team.

A sub-surface cultural heritage test site, similar to what occurred 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:
Commence when project approval granted.
