Advancing water pollution emissions modelling in cities of the future. This project aims to advance stormwater pollution modelling and enhance its link with urban development. Management of stormwater pollution by industry often results in inadequate strategies and, crucially, sub-optimal financial investments. Since this is unlikely to improve in light of urban growth and climate change, addressing decade-old pollution modelling knowledge gaps and the lack of a multidisciplinary approach to stormwater pollution management is urgent. The anticipated outcome is a modelling tool which industry can use to manage stormwater pollution in changing cities through smarter and economic technology and policy.Read moreRead less
Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in res ....Sewer corrosion reduction through model-supported ventilation control. Ventilation is one of the key technologies for sewer corrosion control. However, its design and operation are currently based on experience and empirical equations, often leading to unsatisfactory results. By integrating in-depth laboratory and pilot-sewer studies under defined conditions with extensive field investigations, this multidisciplinary project aims to develop critical models to predict the corrosion process in response to ventilation and dynamic wastewater and atmospheric conditions, enabling model-based sewer ventilation design and operation. The project also aims to deliver novel, field-demonstrated ventilation strategies. The project findings will be incorporated in the Australian ventilation design and operation guidelines.Read moreRead less
An integrated approach to iron salt use in urban water systems. The project aims to develop and demonstrate an integrated and innovative strategy, and the associated science and technologies, to achieve multiple beneficial uses of iron salts in an urban water system. The project intends to use iron chloride to replace the most commonly used alum as a coagulant in water treatment. The same iron is then further used for corrosion and odour control in sewers, phosphorus removal in wastewater treatm ....An integrated approach to iron salt use in urban water systems. The project aims to develop and demonstrate an integrated and innovative strategy, and the associated science and technologies, to achieve multiple beneficial uses of iron salts in an urban water system. The project intends to use iron chloride to replace the most commonly used alum as a coagulant in water treatment. The same iron is then further used for corrosion and odour control in sewers, phosphorus removal in wastewater treatment reactors and hydrogen sulfide removal from biogas in an anaerobic digester. The strategy is expected to substantially reduce the use of chemicals in the entire urban water system, delivering large economic and environmental benefits to urban water utilities.Read moreRead less
Sources, sinks and processes of faecal contamination in urban estuaries: a case study of the lower Yarra River estuary. The Yarra River estuary is highly contaminated with faecal pollution, reducing the useability of Melbourne’s most iconic feature. This project will provide the necessary understanding to help mitigate faecal sources, with the ultimate aim of reducing the risks to users of this estuary.
Sewer Monitoring and Management in the Digital Era. Overflow, flooding, corrosion, and odorous emissions are persistent issues for utilities managing sewers. Current sewer maintenance is reactive, and focuses on solving problems in local networks, despite that optimal solutions require a system-wide approach. Capitalising on recent development in IoT sensors, wireless transmission, and machine learning, this multidisciplinary project aims to develop digital-twin supported data analytics for proa ....Sewer Monitoring and Management in the Digital Era. Overflow, flooding, corrosion, and odorous emissions are persistent issues for utilities managing sewers. Current sewer maintenance is reactive, and focuses on solving problems in local networks, despite that optimal solutions require a system-wide approach. Capitalising on recent development in IoT sensors, wireless transmission, and machine learning, this multidisciplinary project aims to develop digital-twin supported data analytics for proactive sewer management including network-wide real-time control. The project aims to generate significant social, environmental and economic benefits by enabling utilities to better protect public and environmental health, reduce sewer odour and greenhouse gas emissions, and extend sewer asset life.Read moreRead less

Data-driven water quality treatment management decision support system. This project aims to develop a robust decision support system to predict manganese and the character and concentration of dissolved organic matter in drinking water reservoirs, using intelligent algorithms and data collected through remote autonomous instrumentation. These predicted water quality parameters could be used as model input variables to provide real-time decisions for plant operators on the required treatment regime for incoming raw water, and advise them on the optimal reservoir offtake depth. This will potentially minimise treatment costs and health risks for consumers. The ultimate goal is to significantly enhance current water supply management practices.Read moreRead less
Smart management of disinfectant in chloraminated water-supply systems. Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems.

Smart management of disinfectant in chloraminated water-supply systems. This project aims to develop an adaptive, real-time control system for managing disinfectant residuals in chloraminated water supply systems. While chloramine delivers microbiologically safe drinking water in warmer climates and in long distribution systems, it is largely unpredictable, costs water utilities millions of dollars annually, and has uncertain benefits. This project’s control system will be guided by quantitative models formulated from multi-pronged, fundamental experiments. The project will quantify microbial chloramine decay and determine mechanisms to increase predictability. The project will develop and demonstrate a real-time control technology which delivered microbiologically safe, cost-efficient drinking water to people in warmer climates, despite warming climate and increasing population.Read moreRead less
