REPORT
anglesea borefield project
Barwon Water is investigating a new groundwater
resource for the greater Geelong region. The
Anglesea borefield project, identifed in the Victorian
Government’s Central Region Sustainable Water
Strategy, has been brought forward three years in
response to declining surface water storages, the
uncertainty of a return to average rainfall, and to
meet future growth in the region.
Alcoa needs to ensure that all environmental and
heritage factors are assessed, including avoiding
construction within the Anglesea Heath wherever
possible; avoiding areas of high conservation
significance; and avoiding known aboriginal
heritage sites to minimise the impact of
construction upon the values of the Anglesea
Heath.
It is anticipated the borefield could provide up to
twenty megalitres of water a day to customers in
the greater Geelong region, including Geelong, the
Bellarine Peninsula, Torquay, Anglesea,
Winchelesea, Lara and Bannockburn, by the
summer of 2008/09.
The Agency Reference Group, formed in March,
meets monthly to discuss and streamline the
environmental and legislative process needed to
satisfy each agency’s requirements for project
approval. The group includes representatives from
Alcoa in addition to the EPA, Southern Rural
Water, DSE, Parks Victoria, Surf Coast Shire and
Corangamite CMA.
The Anglesea borefield will tap into the Lower
Eastern View aquifer which extends from the
eastern edge of the Otway Ranges and flows in a
south easterly direction deep under Anglesea and
beyond.
Two borefield investigation zones have been
identified. A northern investigation zone is located
in the vicinity of Barwon Water’s Forest Road
basin site and a southern investigation zone is
located adjacent to Coal Mine Road, along the
southern boundary of the Alcoa coal mine.
A pipeline is required to link the southern and
northern borefield sites to the pre-treatment plant
at the Forest Road basin, and the pre-treatment
plant to Wurdee Boluc Reservoir. The preferred
pipeline alignment weaves it’s way through the
Anglesea Heath from Coalmine Road to Forest
Road. As land managers of the Anglesea Heath
Consultants GHD Pty Ltd are working with Barwon
Water to deliver this project including providing
information and consulting with the community.
The project information centre includes:
> a project office
office: on the corner of Harvey and
Parker Street, Anglesea (the former DSE and
Parks Victoria office). A project team member
om
will be in the office every Tuesday fr
from
9.30am-4pm to discuss the project. Please
phone 5226 2516 to make an appointment.

OUR ENVIRONMENT AND OUR EMPLOYEES..
So Phil, you’re the OHS Coordinator - how do you
come to featur
e in this month’
s Env Report?
feature
month’s
There’s a cross over between Safety and Environment where
asbestos is concerned. Potential exposure to asbestos presents
an environmental and health risk and we need to ensure that our
people are aware of the health impacts and the correct handling
requirements. From an environmental view, asbestos once
removed from use is then considered a waste material, and it is
disposed of in our onsite dedicated landfill.
What is the status of asbestos training?
As part of a review of training requirements for everyone onsite, it
was determined that there was a need for a revamp of the
asbestos awareness training material we present to all
employees. Prior to formalising our training needs analysis, this
material has generally been delivered in preparation for outages
but now will be a regular feature of our training profile.
And how is this year’
s training shaping up?
year’s
The general awareness package has been developed and
training will be rolled out in September by myself or Nicci Marris.
This will be for all Alcoa personnel and site-based contractors.
