Video: Andrew Hansen on conserving Melbourne's water supply
Andrew Hansen: When I moved to Melbourne, I thought, "At last!
"Good coffee, great culture,
"really great intellectual conversations
"about the weather."
Because we do that here, don't we?
We talk about the rain, the cold, the heat,
all the weather types.
Well, maybe it's because this city of ours
has relied on the weather for our water supply.
If there was enough rain, we were OK.
But if not, well,
tighter and tighter water restrictions
while we looked to the skies.
We can't rely on rain anymore.
Worldwide water conservation
is one of the biggest issues of our time.
First big challenge is climate change.
That means it's raining less,
and when it does rain, our land is drier,
so it soaks up more water,
leaving less to flow through to the dams.
Climate change also makes bushfires more likely.
Now, they threaten nearby dams
and take water to put out.
Then there's the fact that
everyone wants to live in Melbourne,
So, everyone wants to join us
in Australia's fastest growing city.
And what do more people need?
Which means more water.
Now, the good news is, we have a plan.
and, breaking news, it's not all about the weather.
Instead, it's all about diversification.
Now, that means more stormwater
and recycled water,
you know, for non-drinking uses.
Means things like green roofs, raingardens
and plumbing that's clever
and not at all selfish,
It means using desalinated water.
And it means everyone doing their bit.
Now, we only need to save this much water each day
to make a difference.
Chances are...we can do this by asking ourselves
the big questions.
Do you turn the tap off when brushing your teeth?
Can you get out of the shower a minute earlier?
If it's yellow...
..do you let it mellow?
Now, there's a conversation to replace the weather.
But the bigger conversation
and the one we all need to have
is about conserving water.
I'm talking reaching our daily target
of 155 litres per person per day or less.
