Activity 2

How is water recycled?

  1. Go to The Source August 2003 - Public Service
    • What is stormwater? Where does stormwater normally flow?
    • Briefly outline the aim of this recycling project.
    • Use a sketch and annotations (notes) to describe how this system works.
    • List all the ways this project has been measured as a success.
    • What were the shortfalls in this pilot project that will be rectified in future projects?
  2. Go to The Source May 2002 - How on-site recycling turns a liability into an asset
    • Describe how on-site recycling works.
    • List the advantages of on-site recycling.
    • What uses could be made of on-site recycled water? How is this process utilised in Tokyo?
  3. Go to The Source October 2001 - Recycling breaks new ground

    Transurban is a company that has been in the news as a result of its CityLink tunnel project.

    • What is an aquifer? What does it mean to recharge underground aquifers?
    • Describe what happens to groundwater around underground structures. What could happen to the surface ground and structures if aquifers are not recharged?.
    • Use the diagram and text to describe the current recharge situation in the CityLink tunnels.
    • Use the second diagram and text to describe how recycled water will be used to attain the same results.
  4. Go to The Source May 2002 - How green are our gardens?
    • Outline Melbourne Water's recycling commitment.
    • Use the diagram and text to draw an annotated flow diagram to show how this recycling project works.
    • What grade does the EPA give the final water product?
    • Describe the benefits of this project.
  5. Go to The Source April 2001 - The $52M model
    • Describe the location of the Virginia market gardens.
    • What has happened to the groundwater in this area over time? Why?
    • What do farmers now use for water on their crops?
    • Draw a diagram to show how the process of recycling occurs in this project.
    • How much effluent is used in this project? What plans are there to increase the amount of effluent used (consider times of off-peak water demand)?
    • What other benefits are there as a result of this project?
