Stormwater Victoria is excited to invite you to participate in our 3-part Flow Targets Event Series in 2023.
Introduced in 2018 and supported by the EPA’s Urban Stormwater Management Guidance in 2021, flow targets represent a significant shift for the stormwater industry. This 3-part series has been designed with industry, for industry.
Like the introduction of stormwater quality objectives, adoption of the targets will take time. We don’t have all the answers, but as an industry it’s important that we share what we do know and take the next steps together.
The registration fee includes attendance to two (2) Webinars and one (1) Breakfast Seminar. Each event will build on the previous event and registration to only one of these events is not available.
Member Registration Fee: $95
Non-Member Registration Fee: $155

Event Series Part 2: Breakfast Session
Changing Stormwater Management Practices and New Approaches
Building on the first event of the Flow Target Series, this breakfast session will focus on the changing practices within the stormwater industry, as a result of the shift in flow targets. New stormwater management approaches/solutions which are currently being considered across the stormwater industry will be presented and discussed.
When achieving flow targets, no one size fits all. Interventions will differ based on demands, storage options, rainfall characteristics and the type of development. What we do know, is that contributions from lot, precinct and regional scale interventions all play an important role and industry collaboration is essential to a transformational shift, that will inevitably take time.
This will give attendees an understanding of what is currently being done to achieve the new flow targets, and provide examples of new stormwater management approaches and options. Supporting industry with these new approaches will be the launch of the Melbourne Water’s Stormwater Industry Guidance Program; with a project overview and unveiling of an industry survey to capture industry guidance needs.

Jamie Comley |
Jamie is an Environmental Engineer, Urban Planner and Geographer who has worked in sustainable water management for almost 20 years. His experience encompasses a broad range of strategic, technical, policy, engagement and land use planning aspects of IWM, WSUD and urban sustainability. With a background in water authorities, local government and consulting, and a passion for IWM capacity building, Jamie has a strong appreciation of and a keen interest in the issues facing our water and development industries. He is currently project managing the development of the Stormwater Industry Guidance Program Plan, recently initiated by Melbourne Water. |

Gayani Chandrasena |
Gayani is a Civil Engineer with 12 years of combined research and industry experience in Water Sensitive Urban Design (WSUD). Gayani developed a strong track record in urban stormwater management through her involvement in CRC for Water Sensitive Cities as a PhD candidate. Since transitioning to the industry as a consultant in 2016, she has demonstrated the ability to translate research knowledge into practice. Her excellent analytical thinking and communication skills developed through research careers and ability to see the ‘big picture’ approach have been highly valuable in delivering a several IWM/WSUD projects. Gayani has developed an in-depth understanding of the Healthy Waterways Strategy stormwater volume targets through assisting the annual progress reporting in the past two years. |

Aaron Dowling |
Aaron is a Civil Engineer with 12 years’ experience in WSUD design, integrated water management and strategy development gathered during his career spanning across the public and private sectors. He is passionate about the design and implementation of innovative water servicing solutions that deliver high value community outcomes while protecting and enhancing the natural environment. Aaron has developed his strategic, analytical and problem-solving skills from broad exposure to the development industry standards and practices. Leveraging these qualities, he has developed tools, authored guidelines and manuals and delivered training sessions to support industry in designing and delivering IWM solutions. He has also led the delivery of several major IWM Plans and WSUD masterplans across Victoria, incorporating adaptive IWM pathway planning approaches. |
Event Series Part 3: Webinar Session
Modelling New Assets
Closing out the event series, our final webinar aims to show industry how they can address flow volume reductions using examples and case studies to demonstrate modelling approaches. New stormwater management solutions which have been showcased in the previous workshops will be reintroduced within a modelling context to see how they differentiate from typical drainage assets.
The introduction of flow volume reduction targets introduces scrutiny into how we select and justify losses in our modelling. Overestimating losses can help achieve flow volume reduction targets but raises questions into the impact on the groundwater table, while underestimating losses can lead to significant increase to treatment areas. This event will discuss the sensitivity around losses and how to consider both scenarios and ensure that the losses adopted are fit for purpose, and modelling is grounded in reality.
The modelling of flow volume reduction targets will be a learning exercise for all involved as it opens councils and authorities to different modelling and assumptions that can be difficult to dissect and review. Showcasing selective worked examples will help understand the modelling of new assets, as well as inform councils and authorities on important aspects to review and further probe.

ZInta Lazdins |
Zinta is a registered landscape architect with nineteen years' experience across private and public sectors in greenfield development, capital works, and strategic planning. She spent the first five years of her career working in private consultancies, developing an interest in water management and water sensitive urban design through project work. Moving into the public sector, she worked at Wyndham City Council in Melbourne’s western growth corridor for over seven years, delivering landscape and urban design capital works projects and reviewing planning submissions and advocating for WSUD opportunities. Always looking for opportunities to learn and follow her passion for improved water management and environmental outcomes for the community, in 2011, she was selected to take part in the 2012 International Water Sensitive Cities Study Tour. Zinta has been at Melbourne Water since 2016, as an Urban Designer, working to embed urban design thinking and methodologies through projects, such as visitor facilities at the Western Treatment Plant that incorporate water literacy. She has also worked as a flood strategy officer during the development phase of the current Flood Management Strategy, and is currently the Stormwater Program Lead. |

Dr Dale Brown |
Dale is passionate about protecting and improving the health of our waterways as well as integrating water and green space into urban environments. He is looking forward to a day where our local urban creeks can sustain great biodiversity and we can swim without worrying about stormwater pollutants. He has been involved across the stormwater and integrated water management space from policy through to design and maintenance of assets but is perhaps best known for his expertise in and contributions to modelling and guidelines. Dale has recently been pursuing a range of efforts to expand the thinking of industry beyond stormwater quality to address the challenges of urban stormwater excess flows discharging to waterways. These have ranged from development of policy, strategy, design and modelling guidelines through to a deep dive into research on stormwater volume reduction performance. He is also involved in pilot projects seeking to demonstrate the viability of reducing stormwater volumes at the lot scale through to regional stormwater harvesting. |
