Designing streetscale raingardens

Presenters/trainers:

Dr Robin Allison, DesignFlow

Robin is a foRobin Allisonunding Director of DesignFlow, a specialist water sensitive urban design consultancy based in in SA, Victoria and Queensland.

He has more than 20 years’ experience in stormwater management and in particular integrating WSUD into urban spaces to protect aquatic ecosystems while enhancing people’s enjoyment and appreciation of water.

He has delivered projects from streetscape scale to regional wetlands and a focus is often on retrofitting systems within constraints of existing urban areas.  All of the systems employed use vegetation as a key driver of water quality improvement and promote green infrastructure.

Ralph Williams, DesignFlow

Ralph is a CRalph Williamsivil Engineer with a Masters in Hydrology and Water Resources and has 20 years’ experience in Australia and overseas.  He has a particular interest in water treatment, recycling and aquifer storage and recovery.

His practical skills in design and construction supervision compliment his conceptual design and modelling approach ensuring that strategies and plans are practical and can be easily implemented.

Applying his highly technical design skills to help develop community orientated outcomes as part of broader water sensitive urban design objectives is a major focus for Ralph.

This training is supported by the EPA Catchments to Coast Raingardens 500 Program and the Australian Government National Landcare Programme.

Places are strictly limited to 25

Learning outcomes

Local Government and the development industry are increasingly looking to bioretention as a preferred solution for urban stormwater quality management.

Learn how to design successful bioretention systems that meet multiple design objectives, including:

  • Stormwater runoff pollution reduction
  • Long-term function
  • Ease of maintenance
  • Effective integration with public spaces and other infrastructure
  • High-amenity value

Obtain worked examples of designs of tree pits, street-scale solutions and bio-retention basins.

Who should attend?

  • Design engineers (local government and consulting)

Course content

  • What is a biofilter?
  • Expected system performance and criteria
  • Designing for successful long-term operation
  • Hydraulic design including inlets/outlets, overflow and underdrainage
  • Sizing using MUSIC including treatment performance
  • Filter media properties and specifications
  • Saturated zone versus drained systems
  • Dealing with site constraints, e.g. existing services, pedestrian trip hazards and integration with existing stormwater infrastructure
  • Design for maintenance including access, scour protection and flushing
  • Requirements for successful vegetation establishment, species selection
  • Example installations including tree pits, street side pods and bio-retention basins

Core competencies attained

  • An understanding of bio-retention system function and components
  • An understanding vegetation for nutrient removal and aesthetics suited to SA conditions
  • An understanding of growing medium specifications.
  • An understanding of inlet and outlet structures design to facilitate high function
  • An ability to design a simple bio-retention system

Learning activities

  • Design of bio-retention system
    (Participants are encouraged to bring along their own case study to consider in small group workshop sessions)

Delivery method

  • Face-to-face presentations
  • Interactive discussions
  • Workshop case studies

Learning resources

  • Presentation handouts

Note: Attendance at the recent workshop Introduction to Adoption Guidelines for Stormwater Biofiltration Systems delivered by the CRC for Water Sensitive Cities is desirable background, but not essential for attendance at this course.
