Webinar – The private experience of managing stormwater quality by Ruby Ardren @ Virtual
Mar 11 @ 6:07 am – 7:07 am


Ruby will introduce you to the results of her recent exploratory study completed for a Masters of Research, which identified that stormwater quality improvement devices on private property were not being maintained or even retained. Both individuals and representatives of community title owner’s corporations were interviewed and provided feedback on having devices on their land, maintenance practices and awareness of the legal controls they were subject to.

Ruby will provide a brief (approximately 20-minutes) presentation, followed by Q&A with attendees.

This is a free webinar provided in collaboration between Stormwater Queensland and Stormwater NSW. Attendance will contribute to the CPD of attendees.This webinar is proudly sponsored by AssetLogue.


Integrated Urban Water Cycle Management Webinar @ Virtual
Mar 29 @ 12:30 pm – 1:30 pm

Stormwater NSW are pleased to announce the first technical webinar of 2021: Integrated Urban Water Cycle Management featuring Dr Peter Coombes from Southern Cross University and Sylvie Spraakman from the University of Toronto.

This webinar will focus on the need to reframe stormwater drainage as integrated management of the urban water cycle from a design, economic and policy perspective. This approach is in line with the Runoff in Urban Areas, Book 9 in Australian Rainfall & Runoff (2019), co-authored by Peter Coombes.

Sylvie Spraakman will share the outcome of her PhD research on the performance of ‘mature bioretention’ in integrated urban water cycle management and her findings of recent investigations into the long-term hyperformance of Canadian bioretention cells.

Peter’s presentation will look at the broad aspects of integrated urban water cycle management and will focus on the ‘Urban Book’ that has been developed to utilise and compliment the broader set of tools in AR&R used to manage the water cycle. Sylvie’s presentation will focus on the assessment of the long-term performance of bioretention, one element of integrated water cycle management.

This webinar is free to attend and registration is now available by clicking on the link below.

Operations and Maintenance Manual Training @ Canada Bay Club, 4 William St, Five Dock NSW 2046
May 25 all-day

Workshop Overview

This workshop is aimed at Maintenance Managers and Cleaning Contractors, as well as Council staff involved in the sizing, siting and approval of stormwater treatment measures.  This is a new course developed by Stormwater NSW.

This workshop focuses on the new Operations and Maintenance Guidelines, produced by Stormwater NSW, that have become the industry standard and reference document for the maintenance of stormwater assets.

Topics to be covered include:

  • An introduction to the types of treatments, their classifications and purposes
  • An introduction to the types of GPTs and their functionality (if you understand how they work, then you’ll understand how this impacts cleaning)
  • The reality of monitoring, regular cleaning, and annual/comprehensive cleaning
  • Quick coverage of 90% of proprietary devices
  • A more detailed focus on the 4 devices that have 90% of the market
  • Cleaning specifications for these – to include in tenders, and be used on the ground
  • Secondary treatment/Green treatments – in summary only
  • Dewatering – a problem for every site
  • Field validation of performance, cleaning results
  • GPT auditing and WSUD auditing
  • Costing – how much should cleaning cost
  • Budgeting and bean counters – how to get the money to do it right
  • Results, reports and record keeping – why
  • Tips for improving device performance – get better bang for your buck

A copy of the Guidelines must be purchased for all attendees. Organisations registering multiple delegates are only required to purchase a single copy of the manual. 

Spaces are limited. Should you have any questions please contact GEMS Event Management Australia on +61 2 9744 5252 or email

Climate change and its effect on flooding
Jul 19 @ 12:30 pm – 1:30 pm

Topic: Climate change and its effect on flooding


Mark Babister

Monique Retallick

Date:  Monday, 19th July 2021

Time:  12.30pm – 1:30pm

Description: ARR 1987 acknowledged the emerging issue of climate change. ARR 2019 provided National guidance on climate change related rainfall increases based on advice from an expert group including CSIRO, BOM and various academic experts.

The major areas where climate change will impact flooding are:
  • Design rainfall intensity-frequency-duration.
  • Storm type, frequency and depth.
  • Rainfall spatial and temporal patterns.
  • Antecedent conditions.
  • Changes in sea level.
  • The joint probability of storm surge and flood producing rainfall.

This hour long seminar will cover what is the current advice on climate change relating to flooding and how to implement it in practice. It will also cover how the current interim advice may be superseded. The seminar will discuss how climate change will affect urban catchments versus rural catchments.

This webinar will include an audience Q&A session. Attendance is free and you do not have to be a member of Stormwater NSW to participate. Please feel free to bring a friend or colleague with you.


Webinar – Towards Best Practice Bioretention Specifications
Oct 13 @ 1:00 pm – 2:00 pm

Blacktown City Council and Healthy Land and Water have recently undertaken projects to update their specifications for bioretention filter media, transition and drainage layer materials. These projects arose from (i) gaps in the science related to media configuration to achieve desired outcomes and (ii) difficulties sourcing materials complying with specifications.

While the projects produced updated specifications, the above issues remain and it has been recognised that, in order to successfully implement bioretention systems in the future, they need to be addressed.

This joint 1-hour Stormwater Queensland-Stormwater NSW event will include succinct presentations from Blacktown City Council’s Mark Liebman and Ben Penhallurick, Healthy Land and Water’s Glenn Browning and Contech Engineered Solutions’ Craig Fairbaugh, and interactive discussions and Q&A with attendees.

Registration is $10.

A certificate of attendance can be provided upon request.
