Roseworthy run-off ready for re-use
A PROPOSAL to expand the Gawler Wa-
ter Reuse Scheme (GWRS) into Rosewor-
thy's industrial area could reduce the risk
of flooding there and attract development,
while also insuring the scheme from the
impacts of dry climate conditions.
Light Regional Council is currently in ne-
gotiations with the scheme's operator, Buny-
ip Water, over a plan to accept additional
stormwater from the Roseworthy Industrial
Estate, via council's Flett Road stormwater
The proposed scheme expansion is esti-
mated to cost $250,000 and would involve
the design and construction of a balance
tank, pump and 100mm PVC rising main.
It would connect into the GWRS pipeline
at the Thiele Highway, and require minor up-
grades at other GWRS locations.
In a report presented to elected members at
council's December meeting, council's eco-
nomic development general manager, Kieran
Chappell, said the extension was needed to
alleviate flooding of its basin, during periods
of both average and above-average rainfall
It could also help attract development
within the Roseworthy Industrial Estate,
with only about half of the estate's allot-
ments having been developed for industrial
purposes to date.
Constrained stormwater management in
the area has previously been identified as a
possible impediment to development in the
Industrial Estate, a previous council report
According to Mr Chappell, the proposed
GWRS expansion could function as an al-
ternative option to the $80,000 worth of
planned stormwater management works for
the area, that were budgeted for in council's
Accelerated Infrastructure Program.
Those works were planned to involve
pumping stormwater from the basin west-
wards into the natural drainage path within
the rail corridor.
"Whilst works to address stormwater man-
agement from the Roseworthy Industrial
Estate are budgeted and scheduled to occur
prior to winter 2018, the proposed infrastruc-
ture is a discharge mechanism, only, that
does not reuse the stormwater resource," Mr
"Ideally, the 40ML industrial estate basin
can and should be harvested for beneficial
Mr Chappell said, along with alleviating
flooding concerns, the proposed expansion
would further insure the council against hav-
ing to pay a sub-license fee rebate in dry cli-
mate years, when flows in the Gawler River
Council is currently committed to sup-
plying up to 1.6GL of water a year to the
scheme's foundation customers, to avoid
having to pay them the rebate.
"The expected harvest from the basin is
currently in the order of 20,000KL pa (kiloli-
tres per year)," he said.
"However to break even on the GWRS ex-
pansion investment, only 5300kL pa would
need to be harvested.
"Hence, there is contingency in this pro-
posal in the fact that the financial benefit is
expected to outweigh the costs by about four

Saturday burn-off to be trialled
CONTROLLED burn-offs could soon
be permitted on Saturdays in Light Re-
gional Council, after elected members
voted to support an initial trial during
March and April.
Currently, the council's Fire Pre-
vention Office can only issue permits
for broad-acre or stubble burning in
the Lower North, Monday to Friday --
consistent with the guidelines adopted
by the Flinders, Mid North and Yorke
Bushfire Management Committee
However, early last year, the Kapunda
Country Fire Service (CFS) suggested
an extension to permit weekend burn-
ing, to take advantage of the availabil-
ity of extra members on Saturdays and
In a recent report to council, Light
Regional Council strategy and devel-
opment general manager Craig Doyle
said subsequent consultation revealed
the concept was not supported by CFS
volunteers across the broad extent of the
CFS's Region 2.
"However, it is understood that the
weekend burning proposal was mostly
supported by local LRC CFS groups if
it is for Saturday only," he said.
"Council's Fire Prevention Officer
has the discretion of allowing this to oc-
cur and can be guided to consider this if
council indicates it is supportive of it..."
"...[However], staff also strongly rec-
ommend that a process is undertaken
to advise the broader community in ad-
vance of such a change, as the broader
community is not accustomed to burn-
ing on weekends."
"It is noted that allowing weekend
burning would also likely need to con-
sider the outcomes of peak industry
body discussions concerning manage-
ment of 'smoke taint'."
If the trial goes ahead, the results will
be presented to council at the end of
2018, ahead of any permanent changes
A restriction on weekend burning
does not apply in the Adelaide and
Mount Lofty Ranges area (incorporat-
ing Gawler), as there is less distance be-
tween the stations that need to support
each other if there is an emergency.
WASLEYS Primary School has benefited from a
State Government grant scheme, aimed at increasing
parent participation in student learning.
The school was one of 39 public schools and pre-
schools selected to share in $80,000, under the Parent
Initiatives in Education grant scheme, to help hold its
annual Science Expo.
As part of the expo, students head outside to move
between a range of science-related activities, with last
year's experiments covering water, magnetism, gears,
geology, sound, dinosaurs, and more.
Students from neighbouring schools also attend, as do
Sci World and Scientists in Schools representatives.
The event is made possible by the team of parent and
school-family volunteers who help man the different ex-
