Sydney’s current population

4,284,379Sydney’s projected population by

2031 is 5.3 million

In 2008, the total demand for water in Sydney was

630 087 Mega litres. * whilst total supply was only 592,000 ML

1 Megalitre is the equivalent of an OLYMPIC SIZED SWIMMING POOL

DEMAND AND SUPPLY BALANCE

Sydney is serviced by 21 dams, Warragamba is the largest servicing 80% of Sydney’s water

CRISIS

Sydney will run

out of drinking water

by 2038 if water cannot

be used efficiently to

reduce the rate of

consumption

PREDICTED CALCUALTIONS OF WHEN SYDNEY WILL RUN OUT OF WATER

Source: table compiled from key figures from Sydney water, waterforlife and SCA

Comparison between total water demand and total supply

PROBLEMS AND SOLUTIONS

REDUCE the use of water from the residential demand side,

as residents use 70% of fresh water supply

Source: 2006 SoE

TARGET

Reduce demand for drinking water by 40% by 2038.

The overall goal would be achieved by our series of water saving initiatives:

Reduce water consumption between 5 – 25% by 2013

Standard detached dwellings to be 80% water sustainable by

2038

• 25% of the standard detached dwellings to have a

rainwater tank by 2010

50% by 2020 80% by 2035

If this is achieved, the 2038 water crisis would be avoided.

SOLUTIONS

INTIATIVE ONE – Proposed Water Price increase by 50%

GOAL: To reduce demand and to increase revenue

for other initiative schemes

TARGET: 5% - 25% reduction in water demand every year

INCLINING BLOCK PAYMENT SYSTEM

Price increase varies according to different levels

of use

Low – 40%, Medium – 45%, High – 50%

*NB: Threshold levels will be determined by Sydney Water’s usage calculation model

50% INCREASE FROM CURRENT WATER PRICE LEVELS OF

$1.61 PER KILOLITRE TO $2.415

2008 Sydney Water budget performance, the demand amount at

630 087 megalitres at the current price of $1610 per ML, the total revenue was:

$389 000 000

At our proposed new price increase at $2.415 per KL at the highest pricing level/threshold. The profit after the increase before

tax is: =

$701,251,162, a 55% increase in profit between the old price and the proposed

price.

Revenue generated will go towards funding our other water saving initiatives.

We propose that rental properties in Sydney should pay for their water use

452 395 (29.7%) of total occupied private dwellings (ABS 2008)

Profit can go up by 30 – 35% OR

$936,753,486 in one year

POTENTIAL IMPACTS OF PRICE INCREASE

Our research has shown that other cities, who have implemented

price increases between 40 – 70%, have reduced their demand anywhere between 5 – 25%.

This price increase proposal will require changes to the pricing tribunal as part of the legislative framework. This will be reviewed by IPART, under the Independent Pricing and Regulatory Tribunal Act 1992

INTIATIVE TWO – Rainwater Tanks

Targets:

25% will have a rainwater tank by 2010

50% by 2020 80% by 2035 2038:

dwellings 80% water sustainable

SYDNEY WATER – PROPOSED SUB BRANCH

Facilitate the purchase and distribution of rainwater tanks

Co-ordinates the water trading scheme

Revenue subsidises rainwater tanks

WATER CONSUMPTION

244 000 Litres can be captured

off an average size roof per year

988 434 houses = 205 001 ML/

year

Source: www.smh.com.au

HOUSEHOLD CONSUMPTION

A household 209 000 L/year

The amount of rainfall captured 207 400 L/year

= 99% sustainable

REACHING TARGETS

Creating a house 80% water sustainability is obtainable

Reduce the dependence on fresh water by 32.5%

INTIATIVE THREE – WATER TRADING SCHEME

EDUCATION

- Household daily targets

- How they can cut down

- Different mediums

- Impacts of their water use

- Information on rainwater tanks

LIMITATIONS

• People’s behaviour

• Governance

• Nature

HAVE WE SOLVED OUR WATER CRISIS?

• Sydney’s water consumption would decrease by 32.5% due to the 988 434 homes who have collected rainwater from rainwater tanks.

• Sydney’s detached houses would be approximately

85% self sufficient on rainwater

• Sydney’s demand for water would have been reduced from 5 – 25% as a result of the

50% price increase

YES WE HAVE!

• From our calculations, we have predicted that

our initiatives have the potential to decrease demand of our drinking water

by 40% by 2038, therefore

avoiding our CRISIS.

FUTURE DIRECTIONS

• Climate Change

• Totally self sustainable
