Completed as part of BEB801 (Thesis) at Queensland University of Technology (2016).

1. Conceptual Evolution of
WSUD Concepts
Author: Sarah Black (n8594902)
Supervisor: Dr. Prasanna Egodawatta

2. Background: Water Sensitive
Urban Design
 Uncertainty Of Future Rainfall Patterns
 Storm Water - Last Main Unused Urban Water Resource
 WSUD – Harvesting Stormwater
 WSUD – Influences (Urbanisation and Climate Change)

3. Impacts of Urbanisation
 Australia’s Urban Population – 89% (2014)
 Climate Change Is Becoming Worse
 Australia - Fairly Resilient, But Tolerance May Be Exceeded
 It Is Important For WSUD To Be Incorporated Into
Community Areas

5. Negative Quantity Impacts
 Land Use Changes
 Water Cycle – Disrupted
 Higher Rate Of Discharge

7. Negative Quantity Impacts
Continued..
 Elevations In Base And Peak Flows
 Higher Risk Of Flash Flooding
 Rainfall Data Needs To Be Analysed
 Data Presented In IFD Curves

9. Negative Quality Impacts
 Increase Infrastructure Causing More Contaminants
 Increased Run Off Rates  More Sediments And Nutrients
 Sources Of Pollution
 Treatment Incorporated Into WSUD
 Water Guidelines And Quality Objectives

10. Benefits of Urbanisation
 Collection Of Stormwater Runoff
 Encouraging Multi-disciplinary Collaboration
 Improving Livability

11. Collection of Stormwater Runoff
 Promotes:
 Collection
 Recycling
 Treatment
 Re-Use
 For Use In:
 Irrigation
 Dust Supression
 Ornamental Use

12. Encourage Multi-Disciplinary
Collaboration
 Better Results Achieved
 Problem Is Approached In Holistic Way
 Collective Solutions

13. Improve Livability
 Collect, Treat And Re-use
 Maintain Affordable Prices
 Less Destruction
 Protect Waterways

14. Integration of WSUD in Urban
Planning and Design
 Historical Water Management Concepts
• Urban Stream Syndrome
• Past  Capturing And Storing
• Progression  Filtering And Treatment
• Present  Integration Of WSUD Strategies Into Urban Planning
And Design

15.  WSUD Structural Devices
• Constructed Wetland
• Water Body With Vegetation
• Removes Pollutants

16. • Sand Filter
• Filter Bed - Two Compartments
• Removes Pollutants
• Retains Both Fine And Coarse Sediment

17. Constructed Wetlands
Port Phillip, Melbourne, Australia

18. Treatment Train
Heritage Park, Minneapolis, United States

19. The Future of WSUD
 Challenges
• Climate Change And Urbanisation – Catalysts
• Implementation Of WSUD
• Data Needs To Be Analysed

21. The Future Of WSUD
Continued..
 Future Concepts
• Porous Pavement
• Infiltration And Treatment
• Witholds A Fair Load
• Made From Asphalt Or Concrete
• 20+ Before They Need Replacing

23.  Future Concepts
• Treatment Of Water To A Drinking Water Standard
• Level of Treatment Not High Enough For Drinking
• Australia – Water Scarce
• Wagga, Albury and Canberra – Portion of Water Recycled
Stormwater

24. Recommendations
 Further Embrace ‘Multi-disciplinary Collaboration’
 Provide Educational Sessions For WSUD Communities (Which Will
Outline The Economic, Environmental And Social Benefits Of WSUD)
 Undertake Further Studies On How To Treat Storm Water To An
Acceptable Drinking Water Standard And Exploration Of New
Technologies
 Further Develop Porous Pavement Technologies
