Andrew Hansen: When I moved to Melbourne, I thought, "At last!

00:03

"Good coffee, great culture,

00:04

"really great intellectual conversations

00:06

"about the weather."

00:08

Because we do that here, don't we?

00:09

We talk about the rain, the cold, the heat,

00:11

all the weather types.

00:13

Well, maybe it's because this city of ours

00:15

has relied on the weather for our water supply.

00:19

If there was enough rain, we were OK.

00:21

But if not, well,

00:22

tighter and tighter water restrictions

00:24

while we looked to the skies.

00:26

We can't rely on rain anymore.

00:28

Worldwide water conservation

00:30

is one of the biggest issues of our time.

00:32

First big challenge is climate change.

00:35

That means it's raining less,

00:37

and when it does rain, our land is drier,

00:40

so it soaks up more water,

00:42

leaving less to flow through to the dams.

00:44

Climate change also makes bushfires more likely.

00:46

Now, they threaten nearby dams

00:48

and take water to put out.

00:50

Then there's the fact that

00:52

everyone wants to live in Melbourne,

00:53

including babies!

00:55

Selfish babies!

00:57

So, everyone wants to join us

00:59

in Australia's fastest growing city.

01:01

And what do more people need?

01:03

More...coffee.

01:05

Which means more water.

01:07

Now, the good news is, we have a plan.

01:10

It's underway

01:12

and, breaking news, it's not all about the weather.

01:14

Instead, it's all about diversification.

01:17

Now, that means more stormwater

01:19

and recycled water,

01:20

you know, for non-drinking uses.

01:22

Means things like green roofs, raingardens

01:25

and plumbing that's clever

01:27

and not at all selfish,

01:29

like babies.

01:30

It means using desalinated water.

01:32

And it means everyone doing their bit.

01:34

Now, we only need to save this much water each day

01:36

to make a difference.

01:38

Chances are...we can do this by asking ourselves

01:42

the big questions.

01:43

Questions like...

01:45

Do you turn the tap off when brushing your teeth?

01:47

Can you get out of the shower a minute earlier?

01:50

If it's yellow...

01:52

..do you let it mellow?

01:55

Now, there's a conversation to replace the weather.

01:58

But the bigger conversation

02:00

and the one we all need to have

02:02

is about conserving water.

02:04

I'm talking reaching our daily target

02:06

of 155 litres per person per day or less.
