If water consumption does not become more efficiently Sydney will run out by 2038. To help solve this problem in the short term there will need to be an increase in price to help decrease the amount of consumption per household. For the long-term rainwater tanks and trading schemes. The goal is to help reduce the demand (5%-25%) and increase revenue for other schemes.

  • 2.
    • Sydney’s current population
    • 4,284,379
    • Sydney’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 Source: filipspagnoli.wordpress.com
  • 3.
    • Sydney is serviced by 21 dams, Warragamba is the largest servicing 80% of Sydney’s water

    • Australia is THE second highest user of water.......
    AUSTRALIA’S WATER SUPPLY Source: data360.org
  • 5. YET WE PAY THE LEAST FOR OUR WATER
    • 1 Kilolitre of water = $1.61
    • 1 Kilolitre of Dairy Farmers Milk = $2690.00
    • 1 Kilolitre of Coca Cola diet coke = $3760

    • CRISIS
    • Sydney will run out of drinking water by 2038 if water cannot be used efficiently to reduce the rate of consumption
  • 8. 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
  • 9. PROBLEMS AND SOLUTIONS REDUCE the use of water from the residential demand side , as residents use 70% of fresh water supply Source: 2006 SoE
  • 10. 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.
  • 11. SOLUTIONS
  • 12. 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
  • 13. 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
  • 14. 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.
  • 15. 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
  • 16. 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
  • 17. INTIATIVE TWO – Rainwater Tanks
    • Targets:
    • 25% will have a rainwater tank by 2010
    • 50% by 2020
    • 80% by 2035
    • 2038:
    • dwellings 80% water sustainable

  • 18. SYDNEY WATER – PROPOSED SUB BRANCH
      • Facilitate the purchase and distribution of rainwater tanks
      • Co-ordinates the water trading scheme
      • Revenue subsidises rainwater tanks
  • 19. 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
  • 20. HOUSEHOLD CONSUMPTION
    • A household 209 000 L/year
          • The amount of rainfall captured
    • 207 400 L/year
    • = 99% sustainable
  • 21. REACHING TARGETS
      • Creating a house 80% water sustainability is obtainable
      • Reduce the dependence on fresh water by 32.5%
  • 22. INTIATIVE THREE – WATER TRADING SCHEME
  • 23. EDUCATION - Household daily targets - How they can cut down - Different mediums - Impacts of their water use - Information on rainwater tanks
  • 24. LIMITATIONS
    • People’s behaviour
    • Governance
    • Nature
  • 25. 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
  • 26. 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 .
  • 27. FUTURE DIRECTIONS
    • Climate Change
    • Totally self sustainable
