Upcoming Events
Hosted by Stormwater Queensland and Stormwater Victoria, and sponsored by Wave Maintenance.
Topic: WSUD audit, maintenance and rectification insights for assets 5-15 years old.
Presenters: Ralf Pfleiderer – Director at Wave Maintenance
Date: Thursday 17 September 2020
Time: 12.30pm – 1:30pm
Description: This seminar will cover a range of design and construction suggestions gleaned from years of observation and auditing systems, and more recently of maintaining and rectifying raingardens, tree pits and biofilters as part of stormwater harvesting systems. Over the last two years, as director of the new WSUD maintenance company, Wave Maintenance based in Melbourne, Ralf Pfleiderer has been getting up close and personal with mainly assets, doing monthly and quarterly cleaning. This gives you a great insight into how quickly inlets block and sediment accumulates. Over the last two months Wave Maintenance have also rectified over 60 assets ranging in design styles, ages, catchments types and maintenance regimes. The seminar will present aspects that make maintenance easy (and therefore the assets perform well), what designs reduce failure and blockages and what not to do again in the future.
Registration: This webinar is FREE of charge to all.

Topic: Enhancing the Ability of the Agricultural Landscape to Remove Nitrogen: Lessons Learnt
Presenters: Dr Mark Bailey – Director / Senior Scientist at AWC
Date: Thursday 1 October 2020
Time: 1.00pm – 1:45pm
Description: The long-term protection of the Great Barrier Reef requires a co-ordinated and multi-faceted campaign across the atmosphere, ocean and land draining into the GBR. On land, the diffuse movement of sediment, nutrients and pesticides from both the urban and agricultural catchments have been reported to impact the resilience of the reef systems themselves.
While the quality of water draining from the GBR catchments has been extensively measured/modelled, the actual water quality ‘problem’ at the local scale is not well defined. As such, the solution to decreasing the sediment, nutrient and pesticide loads to the GBR in not well understood.
For the past 10 years AWC have been involved in the developed of many strategies for intercepting nitrates and sediments within the agricultural landscape – two priority pollutants for maintaining reef health. This has been a challenging but rewarding experience collaborating with landholders and other stakeholders to develop pragmatic and workable solutions in response to different landholder needs within the individual catchment/farm context.
This webinar will relate the technical and engagement methods employed, outcomes achieved and the mistakes made and how we hope these to assist in the future planning, design and implementation of water quality improvement projects across the agricultural sector. Addressing the challenges facing the GBR requires a significant scaling up of efforts to improve farm and catchment-based management of water quality with input from a broad range of industry bodies, government and non-government organisations, the scientific community and most importantly the farming community. This webinar is intended to assist and guide the many people required to contribute to this effort.

Topic: Challenging the current Queensland regulatory framework for rainwater tanks
Presenter: Daniel Niven, Principal Water Engineer at Engeny Water Management
Date: Thursday 15 October 2020
Time: 1.00pm – 1.45pm
More Details Coming Soon!
Topic: Let’s stop putting stormwater detention in stupid places
Presenters: Dr Rodney Ronalds – Friends Civil Engineering
Date: Thursday 29 October 2020
Time: 1pm – 1:45pm
Description: Stormwater detention is commonly mandated by local Council’s for all new development sites, regardless of their location in the regional catchment. It is also common for engineers to specify stormwater detention using an isolated assessment of peak runoff at the lawful point of discharge of a site only, without considering the surrounding catchments and watercourses.
The first part of this webinar will cover recent research that conclusively shows that detention in the lower parts of regional catchments (where all of our cities are) can cause increased regional runoff and flood probability. Equations will be presented that can be used to calculate the increase/decrease in regional peak runoff that results from urbanisation with/without OSD at varying locations in the regional catchment. The equations are simple and easy to use, with basic inputs requiring a few measurements of catchment areas and stream lengths.
The second part of this presentation will look at some significant rainfall events that occurred early in this year and exceeded the infamous 1% AEP. The actual recorded rainfall patterns over the regional catchments have been modelled to test the equations response to real rainfall.
The third part of this presentation will respond to some of the feedback that the original study has received from industry experts. One of the main topics from reviewers has been the spatial variance of rainfall (what happens if it only rains in part of the regional catchment or the rainfall is not equal over the catchment). A method for randomly distributing rainfall over the catchment as part of a monte-carlo simulation technique in a hydrologic model will be described to address these reviewers’ concerns.
Lastly, a discussion from the audience will be encouraged. Stories involving projects with stormwater detention at inappropriate locations, and any strategies for driving policy change will be greatly welcomed.

Hosted by Stormwater Queensland & IECA
Topic: Erosion and Sediment Control in Queensland – Changes Design Engineers need to be made aware of.
Presenters: Kyle Robson –Managing Director at Topo
Date: Thursday, November 26, 2020
Time: 1pm – 1:45pm
Description: In 2017, the Queensland government updated the State Planning Policy (SPP). The SPP included some significant changes in how Erosion and Sediment Controls are to be designed and managed. Based on a review of Erosion and Sediment Control plans being submitted with Operational Works drawings, it is clear many design Engineers are not complying with the new requirements. This leads to confusion for contractors during tendering and risk of incorrect budgeting or expectations for all involved in the project.
This webinar will provide a simplistic overview of what the changes are, what this looks like and where individuals or companies can find resources to help them transition designs to comply with legislative requirements. The session is focused at Engineers, individuals and companies preparing designs for the urban development sector and will also include a Q&A session where attendees can ask any questions they have on the changes or design process.
This is a joint webinar by Stormwater Queensland and the International Erosion Control Association.
This event may attract CPD points. Please contact your relevant professional Institute or industry organisation to confirm.
Registration: This webinar is FREE of charge to all.

Hosted by Stormwater QLD & Stormwater NSW and sponsored by 
This webinar will be presented by Aditya Singh, a Senior Water Resources Engineer at KCB. Last year, Aditya was part of a project within the Research Development and Innovation (RDI) scheme managed by the Queensland Water Modelling Network (QWMN). As part of the project, he has looked at using a distributed catchment model to improve representation of catchment scale processes and linkages to finer scale hydrodynamic models. The project also saw the use of PEST for parameter estimation and a hybridisation approach involving some machine learning methods to predict water quality.
The webinar will include a short (approximately 20-minute) presentation by Aditya, followed by Q&A.

Topic: WSUD asset management requirements for new development – legislation, development and compliance
Presenters:
Dr Andrew Thomas – Vice President – Stormwater NSW
Daniel Rider –WSUD Compliance Officer at Blacktown City Council
Date: Wednesday 9 June, 2021
Time: 1pm – 1:45pm
Description: In 2012, Blacktown City Council established a Water Sensitive Urban Design Compliance Program. A first of its kind in Australia, the Program aims to increase compliance with legal requirements for the management of privately-owned water sensitive urban design assets in the Council area. This webinar will provide an overview of the Program as well as a project that seeks to improve its capacity to increase compliance with legal requirements. It may offer important insights for local authorities in New South Wales and Queensland seeking to establish their own compliance programs and initiatives.
This is a free webinar provided in collaboration between Stormwater Queensland and Stormwater NSW. Attendance will contribute to the CPD of attendees.
Registration: This webinar is FREE of charge to all.
Trees growing to maturity in streets and civic spaces are commonly the primary objective of urban forest strategies, with stormwater management also a requirement. These trees provide a range of high value ecosystem services, including cooling, shading and enhanced aesthetics.
Understanding the tree requirements for healthy growth is essential – particularly regarding availability of soil-based resources of water, nutrients, oxygen and suitable soil root development conditions.
In this webinar, Geoff Connellan provides an overview of approaches to passive irrigation to contribute to tree canopy targets in streets and civic spaces, and learnings from passive irrigation installations.
Topics covered include tree water demand estimation, tree water use results, system design considerations (e.g., catchment properties, inlet design, site storage, soil volume sizing and water distribution), the limitations of passive irrigation, opportunities for active irrigation and the circumstances that support structured soil systems. Reporting of stormwater system tree performance is reviewed.
This free webinar will include a short (20-minute) presentation by Geoff, followed by Q&A from attendees.
