Conceptual Evolution of Water Sensitive Urban Design (WSUD) Concepts - Sarah Black

  1. 1. Conceptual Evolution of WSUD Concepts Author: Sarah Black (n8594902) Supervisor: Dr. Prasanna Egodawatta
  2. 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. 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
  4. 4. Negative Quantity Impacts  Land Use Changes  Water Cycle – Disrupted  Higher Rate Of Discharge
  5. 5. 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
  6. 6. 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
  7. 7. Benefits of Urbanisation  Collection Of Stormwater Runoff  Encouraging Multi-disciplinary Collaboration  Improving Livability
  8. 8. Collection of Stormwater Runoff  Promotes:  Collection  Recycling  Treatment  Re-Use  For Use In:  Irrigation  Dust Supression  Ornamental Use
  9. 9. Encourage Multi-Disciplinary Collaboration  Better Results Achieved  Problem Is Approached In Holistic Way  Collective Solutions
  10. 10. Improve Livability  Collect, Treat And Re-use  Maintain Affordable Prices  Less Destruction  Protect Waterways
  11. 11. 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
  12. 12.  WSUD Structural Devices • Constructed Wetland • Water Body With Vegetation • Removes Pollutants
  13. 13. • Sand Filter • Filter Bed - Two Compartments • Removes Pollutants • Retains Both Fine And Coarse Sediment
  14. 14. Constructed Wetlands Port Phillip, Melbourne, Australia
  15. 15. Treatment Train Heritage Park, Minneapolis, United States
  16. 16. The Future of WSUD  Challenges • Climate Change And Urbanisation – Catalysts • Implementation Of WSUD • Data Needs To Be Analysed
  17. 17. 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
  18. 18.  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
  19. 19. 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
