Waterproofing Eastern Adelaide
Project Overview
Waterproofing Eastern Adelaide
is being delivered by the Eastern
Region Alliance (ERA); an alliance
of the seven councils in Metropolitan
Adelaide’s eastern suburbs. The
following five councils are directly
involved in the planning and delivery
of the project:
• City of Burnside (CoB)
• City of Norwood, Payneham and
St Peters (CoNPSP)
• Town of Walkerville (ToW)
• City of Campbelltown (CoC)
• City of Tee Tree Gully (CoTTG)
The Waterproofing Eastern
Adelaide scheme is supported
through funding for the Australian
Government’s National Urban
Water and Desalination Plan and
also the Adelaide and Mount
Lofty Ranges Natural Resources
Management Board, which
assisted the Councils in the
initial stages and continues to
be an integral contributor.
financially viable, subject to further
costing of a complete design.
These innovative Councils have
been working together to plan and
now implement Waterproofing
Eastern Adelaide, whereby a
leading team of hydrogeologists,
civil engineers, urban designs and
other experts will work together to
identify, harvest, store, filter and
reuse stormwater in the eastern
suburbs. This project is expected
to reduce operational spending on
local reserve irrigation as well as
green our suburbs and enhance the
quality of water that is discharged
to our gulf.
Waterproofing Eastern Adelaide
involves the establishment of
wetlands, biofiltration sites, aquifer
recharge and recovery, pipeline
installations and water storage
facilities.
To date, the ERA Stormwater
Harvesting and Reuse scheme
proposal has progressed through a
number of design stages including
an opportunities study, funding
submission and feasibility study.
The recent feasibility study found the
overall scheme to be technically and
The project team will work with the
community to ensure that these
improvements to our lifestyle and
environment also provide amenity
improvements and educational
opportunities.
The following key sites are likely
to involve some significant design,
landscaping, urban design and
construction work in order to
facilitate this ground breaking
project. The treatment sites in the
scheme include:
• Tusmore Park: Biofiltration/ raingarden (Burnside)
Waterproofing Eastern Adelaide
•
Mahogany Reserve: Wetland (including link to the existing Torrens Wetland/Aquifer Storage & Recovery (ASR)/raingarden) (Tea Tree Gully)
• Felixstow Reserve: Wetland (Norwood Payneham and St Peters)
• Athelstone Reserve: Biofiltration/ raingarden (Campbelltown).
Initial hydrogeological investigations
have been undertaken and concept
designs have been developed for
each of the reserves. The next
stages will include community
consultation, urban design
(where applicable), review and
implementation.
Project Background
In 2011 the ERA was successful in
obtaining commonwealth funding to
proceed with the ERA Stormwater
Harvesting and Reuse Feasibility
Study. This study further developed
the ERA Stormwater Harvesting
Scheme which was undertaken by
the above noted five ERA Councils
as a submission for funding under
the National Urban Water and
Desalination Plan.
The feasibility study involved;
• Undertaking hydrogeological drilling and testing of proposed ASR (Aquifer Storage & Recovery) sites to understand if the underlying hydrological conditions suit ASR
• Site investigations included
reviewing the available space to
construct the treatment facilities, drilling some test bores to prove aquifer presence and capacity
• Consideration of the impact on public open space and adjacent residents
• Detailed financial analysis and costing
• Analysis of three viable scheme options.
The resulting project budget has
been capped at $28 million, with a
cost share of:
• Commonwealth Government $9.5 million
• ERA Councils - $16.5 million
• Adelaide and Mount Lofty Ranges Natural Resources Management Board - $2 million
Project Scope –
Funding Proposal
The scheme includes four treatment
sites and will yield almost 500ML per
annum (or 198 Olympic swimming
pools), which will supply beyond the
current demand of 454ML per annum.
Approximately 40km of distribution
pipework will be constructed under
this scheme.
A combination of directional
horizontal drilling and traditional
trenching will be used to construct
the pipeline. An assessment of the
most appropriate technique will
be undertaken during the detailed
design stage of the project.
Felixstow Reserve
The site conditions at the Felixstow
Reserve are optimal to establish a
large wetland. This was selected
in place of Scales Reserve due to
the potential land contamination
risk and limited open space at
the Scales Reserve site. Due to
the poor ASR conditions at the
Felixstow Reserve site the treated
water will be distributed to Hamilton
Reserve for aquifer injection. The
Hamilton Reserve site already has
an established bore with a significant
yield.
Mahogany Wetland
This site was selected due to the
large achievable yield and as it is
an expansion of an existing scheme
with an established bore, the site
conditions are known to be suitable.
A link to the existing Torrens site
(located upstream along the River
Torrens corridor), provides additional
contingency to this scheme. The
Mahogany Wetland site is the priority
site, however, the existing Torrens
site may be utilised and could
potentially be expanded subject to
the detailed design of the Mahogany
scheme to provide additional
robustness to the overall scheme.
Athelstone Reserve Biofiltration
This site was selected as it has an
established bore.
While the estimated yield at this site
is not particularly high, it does meet
the demand and could be expanded
in the future if required.
tests indicate an expected yield of
approximately 10L/s).
Mahogany Wetland: Existing bores
at this site yield 15L/s.
Tusmore Park
(Hanson Reserve) Biofiltration
Timeframes
This site was selected as it is near a
bore/aquifer of known good supply
(Hazelwood Park) and adjacent to
an excellent harvest site: First Creek.
The project must be constructed
by June 30, 2016. Full yields would
be achieved once the biofilter
and wetland plantings are well
established, which may take a year
or more after they are planted.
A boifiltration site at Tusmore Park
would be located in the north-east
section of the park (within Hanson
Reserve). The biofiltration site will be
aesthetically designed to enhance
local amenity and will not pose any
safety risk to park users.
How to be involved
The ERA Waterproofing Eastern
Adelaide Project Team are keen
to provide a range of ways for
residents, community groups,
businesses, schools, visitors,
commuters and community
organisations to be involved in this
important and progressive project.
You can:
How were the bore sites
selected?
The bore sites were selected based
on the viability of the aquifer and its
ability to contain treated stormwater
injection.
Existing water harvesting
infrastructure
Hamilton Reserve: There is an
existing bore at this site yielding
10L/s and the nearby MARS Sports
site.
Athelstone Reserve: This site has
an existing bore yielding 10L/s and a
recent new bore has achieved 6L/s.
Langman Reserve: A test bore has
drilled at this site with a yield of 15L/s.
Tusmore Park: A test bore has been
drilled at this site and the initial
