Ozwater’26 Presentation on Integrated Sewerage and Stormwater Modelling

In Brisbane on the 27th May 2026 at 12.15pm?

Come and listen to Andy Chan (Melbourne Water Corporation) and Stephen D’Agata (Urban Water Solutions) as they discuss why integrated modelling is necessary to understand the interaction between separate sewerage and stormwater systems.

Combined models of Melbourne’s sewerage and stormwater networks were simulated with design rainfall events (ARR2019 18.1% AEP rainfall intensities and profiles) to provide a clearer picture of how these networks interact during rainfall events. The sewerage system includes emergency relief structures (ERS) that allow sewage to overflow into the stormwater system to protect customers and assets. The picture below shows an ERS at the base of the ladder and the Dandenong Creek at normal flow level.

The figure below is an example of where elevated levels in the stormwater/drainage system (shown on the right) prevent the sewerage ERS from operating. This results in higher surcharge levels in the sewerage network that would be expected, but less overflow to the receiving environment.

Ozwater is an annual three-day conference and exhibition featuring a strong line-up of international and national keynote speakers, scientific and technical papers, case studies, workshops, panel sessions, and poster presentations.

Stuart attends Water Efficiency Conference

Stuart recently attended the AWA & IWA Water Efficiency Conference in Melbourne (EFFICIENT 2025), and it was a fantastic opportunity to connect and reconnect with others passionate about shaping the future of water. The three days’ sessions covered everything from smart metering and leakage detection to behavioural change and digital innovation – all geared toward making our water systems more efficient and resilient. It was great to see how much collaboration is happening across the sector, both locally and globally. This is an excellent biennial global conference recommended to anybody working in water efficiency. We were fortunate that this year it was held in Australia, Efficient 2027 will be held in Lisbon.

WaterAid’s mission is to reach everyone, everywhere with clean water, decent toilets and good hygiene within a generation. Since 1981, WaterAid has reached over 27 million people with clean water and decent toilets (WaterAid, 2019). This vision inspires us, and we hope it inspires you too.

UWS is pleased to donate to WaterAid and support its efforts to provide safe sanitation and potable water to those in need.

Combined with Water4Good we have collectively raised over $3,500, smashing our target of $2,000.
