Stormwater Group

The Stormwater Group was established in the late 1990s to encourage and promote practical solutions to stormwater and road run-off management, by coordinating stormwater knowledge and making it available to practitioners.  Its membership comprises local authorities, regional council representatives and the New Zealand Transport Agency.

In 2002 the Group brought together roading and stormwater managers and researchers to establish what the stormwater issues were.  The evidence presented at this conference has since determined the work programme of the Group.  A series of seminars was conducted throughout New Zealand in 2007, and a second series that addressed tools, techniques and devices for managing road run-off and stormwater was held in March 2008. A special session on road run-off issues and treatment was chaired by the Group at the Stormwater 2009 conference.

Current members are:

  • Graeme Tong, Palmerston North City Council, Convenor
  • Craig Redmond, New Zealand Transport Agency
  • Dale Nicholls, New Zealand Transport Agency
  • Balt Gregorius, New Zealand Transport Agency
  • Nicci Wood, Wellington City Council
  • Ted Taylor, Greater Wellington Regional Council
  • Hayden Easton, Auckland Regional Council
  • Wayne Newman, Administrator
Current Topics
  • Working with NIWA on research to identify how effective existing controls are, and to evaluate innovative stormwater treatment devices.
  • Monitoring of regional council policies relating to stormwater and road runoff
  • Collecting case studies for sharing in workshops and on the website
  • Establishing a Frequently Asked Questions section on the website
  • Collecting information on devices and techniques, and their effectiveness

A "Stormwater Risk Assessment Guide for Road Engineers" in the form of a single-page "Environmental Risk Assessment Flowchart for Road Runoff" with an accompanying report,  that describes the background to how and why the flowchart was developed, its limitations and its intended use has been developed. The Guide and the Flowchart can be downloaded from the bottom of this page. 

The NZTA has published its Stormwater Treatment Standard for State Highway Infrastructure and has run workshops for consultants and interested individuals in the use of the Standard for State Highway projects.  

ARC ran a comprehensive programme of seminars in July on stormwater issues, including presentations on 'Stormwater contaminants and treatment', the new ARC 'Proprietary Devices Evaluation Protocol' and the updated 'TP010 Stormwater treatment devices design guideline manual'. The full seminar programme presentations can be found at http://www.arc.govt.nz/environment/water/stormwater/stormwater-seminar-july-2009.cfm

The Water NZ Stormwater Conference 2010 will be at the Novotel Rotorua Lakeside on 13-14 May.  The programme includes presentations on LID, stormwater management and managing road run-off, and the implications of the reviewed NZS4404 for local authorities and road controlling authorities.  The draft programme is available at http://www.waternz.org.nz/documents/sigs/stormwater/100205draftprogramme.pdf
