Safeguarding Maleny's Water By Alan Lander, Co-op member
Do you know where one of south east Queensland's most significant water
catchment areas is? Here's a clue: you're standing on it.
At a time when water has become one of the nation's most precious commodities
- rural allocations of which are changing hands at skyrocketing prices
in southern states to the extent that some farms are now selling with
or without water rights - Maleny and other communities on the plateau
of the Blackall Range are located in one of the most prized water catchments
in Australia.
And at a time when the region's population is increasing at such a phenomenal
rate, is it not time to be carefully considering development impact on
these local environs?
Residents well know the Obi Obi Creek's passage around the town not only
supplies locals, but also swells the levels of Baroon Pocket Dam which,
at 61,000 megalitres, is the biggest dam on the Sunshine Coast.
Less known by some, is the Mary River headwaters sprout from the westward
side of the Range. Whatever you may think of the proposed Traveston Dam,
it's waters from here that will supply it, in a far more significant way
than actual rainfall on the dam itself.
Even less considered are the headwaters of the Stanley River, also on
the westward side, which make their way to Somerset Dam, which in turn
feeds the all-important Wivenhoe Dam, one of the largest Brisbane catchments.
Last but certainly not least, there are numerous small feeders on the
Range's east side that meander to Ewen Maddock Dam at Landsborough.
Rainfall is high, even during these drought-ravaged times. In fact, according
to local weather and rainfall statistician Patrick Stacey, rainfall in
Maleny during August and September 2007 was considerably higher than the
averages.
Dangers facing our catchment
Division 1 councillor, Dick Newman, is passionate about the need to control
the constant, creeping concreting of the area. He has coined the phrase
'Catchment Central', which aptly describes the present and future importance
of the Maleny area's ecological and economic role, climate change notwithstanding.
Cr Newman has concerns about future land use and that government bodies
are not properly recognising Maleny's status.
"Maleny's status as Catchment Central is not particularly recognised by
government," he says. "It may seem a bit crazy, given that we are at the
headwaters of some major water supplies, but according to government,
the bigger problem in our area is siltation (deposition of silt on the
beds of streams or lakes) of the coastal areas.
"For example, government sees that there is a very big siltation trap
just downstream from us in Baroon Pocket Dam. As for water quality, the
government spent up big on water treatment at Landers Shute, so the bulk
of the funds goes to water treatment rather than water quality prior to
treatment."
Cr Newman, having sat on the board of water supplier Aquagen, does give
a tick to the organisation regarding water quality. As far as he is concerned,
some developments have been simply bad examples.
"The dangers to any catchment are development and lack of funding for
private landholders," says Cr Newman. "In respect to development, Maleny
Woolworths is an example of bad development practices - we spend time,
effort and money teaching primary school children that certain things
like a supermarket car park should not be built near a creek. Big business
then goes and does it.
"A whole lot of creek frontage is in private ownership. Rural landholders
who are trying to make a living from the land really find it difficult
to fund environmental restoration of esplanades. This is why support from
organisations like Aquagen is so important; they can at least help fund
the capital component of restoration, but this still leaves the land owner
to manage and maintain that land.
" The much-vaunted South East Queensland Regional Plan (SEQRP) has helped
to strengthen the area against development threats - but not on its own.
"The SEQRP is probably overall beneficial to the catchment as it provides
a stronger layer of planning control to the catchment area," Cr Newman
says. "The better protection, however, comes from the strong environmental
provisions of the Local Government Management Strategy (LGMS).
" With a new regional council around the corner, some say Maleny and other
towns may lose out on important protection as they get swept up into a
'super-city', but Cr Newman says it is unlikely to affect water.
"The provisions of the SEQRP, LGMS and City Plan are all in place. Probably
the strongest protection we have for the catchment is that there are a
range of infrastructure problems that will prevent further growth in the
area," he says.
According to Peter Stevens, President of Lake Baroon Catchment Care Group
(LBCCG), our catchment doesn't have any real protection, even under the
auspices of the SEQRP. "The SEQRP is subject to review and can be changed,"
says Peter. "The Montville Links was a good example of where Council supported
the development, even though it was outside the SEQRP, and for a while
I thought it might actually happen."
On a positive note, Aquagen Water Board has recently approved $1.8 million
in funding for the Lake Baroon catchment, which LBCCG will use over 10
years for environmental restoration, mostly on private land.
The pipeline problem
There is also one great irony as far as water supply is concerned in the
area, and it concerns Maleny's own supply. The bureaucracy has decreed
that, despite the town having a permanently-running creek through its
centre, a pipeline needs to be built to augment that supply.
In short, this means water that has fallen on and passed through the area,
is to be collected at Landers Shute in order to be pumped back up the
Range to supply the town. Go figure, as the Americans say.
Cr Newman attempts - with a wry smile - to explain the seemingly ridiculous
circumstances.
"The deal with the pipeline is that it will be constructed because our
current system may fail two days in every decade or so," he says. "Any
other solution we come up with is blocked by rules, regulations, red tape
and dollars. Everything we looked at could not be considered due to rules.
"The last go we had was for an additional small off-stream storage (enough
to boost our back up supplies to about two months for a fully developed
Maleny). We could potentially overcome our first problem by getting the
community to sign off on the amount of water - staff want you to have
about 18 months' supply as a back-up."
"(But) in Maleny, it is extremely unlikely that you would ever need two
months, let alone 18 months, of back-up.
"The problem comes with the cost of constructing the back-up supply -
the community would be happy with an earth wall dam (fairly cheap). But
the government now requires dams to be constructed to withstand the effects
of a one in 10,000-year event (e.g. a cyclone from the north meeting a
cyclone from the south over the top of your dam!).
"This may be a very good thing where large bodies of water are stored,
but we are talking about perhaps 50 megalitres which, if suddenly released
in that area, isn't likely to do any major damage.
"Things like storing a bit of highly treated effluent in a natural system
against a dry spell also get ruled out. No matter how highly we treat
it, the EPA [Environmental Protection Agency] is unlikely to approve storage
near the creek in case it spills into the creek.
"Now this may seem silly to you, as the water I'm talking about would
be far cleaner that what's in the creek, but the concern is that the spillage
would mix with elements such as cow pats on the way to the creek and give
a bit of a boost to the nutrient load. It's arguments like this that are
certainly frustrating to the community."
According to Peter Stevens, the pipeline was chosen as the cheaper, easier
option when a more integrated approach should have been considered to
keep our water local.
"Unfortunately, there's a lack of storage for the amount of rainfall we
have, and that issue isn't easily addressed. But it could be addressed
by people supplementing their water supplies with tanks, or more innovative
systems. For example, Maleny High School could collect water on its roof
and supply it to Erowal [Retirement Village]. Both have large roof areas
and one sits above the other - it's a gravity feed.
"We have to put in three or four different approaches to making Maleny
sustainable, so that the local community can have more control over its
own water supply. The attraction of living here is that the water comes
from the area and is collected in the area. You feel like you're living
within the constraints of your environment.
"Perhaps only 30 per cent of people on a reticulated supply need these
measures. It's a pretty expensive pipeline for what are really short periods
of demand, and people [may] then automatically propose more development
because the water is there.
"We are talking to people and trying to get some recognition that this
is a significant water supply area. Nothing in legislation says this is
an important water catchment area. That concerns me. The thing is, what
is the best method for recognising that?
"Other areas, like Wivenhoe, have Declared Catchment status. It may turn
out that Declared Catchment status isn't the most appropriate way to deliver
protection, but it's certainly something that could be done in the interim,
and if the legislation is out of date, then let's bring it up to date...The
problem is, governments look at water resources in terms of dams and infrastructure.
They don't look at it as a living system that needs to be taken care of.
"The new divisional boundaries for the proposed regional council will
now give one voice to most of the Maleny plateau and Blackall Range. Candidates
for the 15 March 2008 election will hopefully carry awareness of the region's
water catchment seriously in the race for the new Division 5 leadership.
