Stormwater Group

Sediment and contaminants from road run-off entering stormwater systems and having deleterious effects on  receiving aquatic and marine environments was identified as a serious issue for road asset managers from the inception of the RCA Forum.  The Stormwater Group was established in 1996 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 determined the work programme of the Group over the following half-decade.  A series of seminars was conducted throughout New Zealand in 2007 and  2008, and a special session on road run-off issues was chaired by the Group at the Stormwater 2009 conference.

The Group has acted as the steering group for research into the vehicle emissions factor in road run-off contamination of stormwater and supported seminars to present the findings. It is currently a part of the steering group for field trials of innovative stormwater treatment technologies.

The Group records its appreciation of the roles played by the late Alan Watton as its convenor from its inception to 2006 and by Graeme Tong of Palmerston North City Council as convenor from early 2007 to 2010, and to Fiona Knight as secretary from its inception to late 2008.

Field Trials of Treatment Devices Performance The Group is part of the steering group for current NIWA research evaluating the performance of treatment devices in field trials.  These fields trials have been extended from nine to fifteen storm events to meet the requirements of the new evaluation protocol.

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 guidance document, can be downloaded from this page.
