Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a yea ....Optimal management of corrosion and odour problems in sewer systems. Pollutants in wastewater undergo complex changes in sewers, leading to the production and release of odorous and corrosive compounds. Despite major efforts and expenditure by water utilities to mitigate these problems, odorous emissions from sewers are still commonly occurring in urban areas. Furthermore, the value of public assets is significantly diminished due to sewer corrosion, costing hundreds of millions of dollars a year in Australia alone. This project is a major joint effort by the Australian water industry and world-leading scientists to generate advanced knowledge and develop effective technologies for optimal odour and corrosion management in sewers, delivering large social, environmental and economic benefits.Read moreRead less
Understanding the Biotransformation Processes in a Sewer System to Achieve Optimal Management. Sewer corrosion and odour emissions are incurring massive costs to the wastewater management authorities.

Sewer corrosion and odour emissions are incurring massive costs to the wastewater management authorities. These problems are primarily caused by the hydrogen sulfide produced by the in-sewer biotransformation processes. Through integrating controlled laboratory experiments, extensive field measurement/experiments and advanced computer modelling, the project aims to generate a fundamental understanding of the in-sewer biotransformation processes, in particular those occurring in sewer biofilms and sediments, and to provide scientific and engineering support to the wastewater authorities to manage their sewers in a more cost-effective way. Emphasis is placed on the integrated sewer and wastewater treatment performance to achieve overall optimal wastewater management.Read moreRead less

Network-wide sewer odour and corrosion management by model predictive control. This project aims to develop and demonstrate, through real-life field studies, a model predictive control approach that achieves cost-effective network-wide mitigation of hydrogen sulphide. The lack of suitable methodologies to support the control designs of chemical dosing units and sewage pumping stations makes network-wide sewer corrosion and odour management a problem. Innovative control methodology will simultaneously manipulate chemical dosing unit(s) and selected sewage pumping station(s), based on real-time prediction of sewage flows and characteristics both at sources and across the network, to ensure optimal delivery of dosed chemicals to mitigate hydrogen sulphide.Read moreRead less
Advances in real-time satellite monitoring of flow in rivers and estuaries. This project plans to improve the monitoring of our waterways by developing a novel moving drifter system that takes flow and water quality measurements along the pathlines of the drifters. One of the key challenges for Australian water management lies in monitoring and managing rivers and estuaries effectively over large geographical areas. Traditionally, instrumentation at stationary points has been used for such monit ....Advances in real-time satellite monitoring of flow in rivers and estuaries. This project plans to improve the monitoring of our waterways by developing a novel moving drifter system that takes flow and water quality measurements along the pathlines of the drifters. One of the key challenges for Australian water management lies in monitoring and managing rivers and estuaries effectively over large geographical areas. Traditionally, instrumentation at stationary points has been used for such monitoring, under the simplifying assumption that a single point adequately represents a very large region of water. By contrast, the Real-Time Flow Logging of Water (RT-FLOW) system expects to provide information from large regions of our waterways, providing stakeholders with more information to enable them to better manage issues including storm surge and erosion. The project also aims to provide improved validation of hydrodynamic models.Read moreRead less
Mega spatial-scale, multi time-scale, ensemble assessment of climate change driven coastal change in South Eastern Australia. Climate change driven variations in mean sea level, storm surges, and waves will change the world's coastline. This project will, for the first time, develop innovative modelling methods to quantify the integrated impact of these climate drivers on coastal erosion along Australia's most developed and populated coastline: Sydney to Brisbane.
A New Approach to Air Traffic Management to Deliver Significantly Reduced Environmental Impact and System-wide Efficiencies. Aviation is often cited as a major contributor to harmful emissions in the upper atmosphere. The primary outcome of this project is the development of tools that will enable aviation industry stakeholders to optimise the deployment of 4-Dimensional User Preferred Trajectories across Australian airspace.

Aviation is often cited as a major contributor to harmful emissions in the upper atmosphere. The primary outcome of this project is the development of tools that will enable aviation industry stakeholders to optimise the deployment of 4-Dimensional User Preferred Trajectories across Australian airspace. It is expected that this will result in significant environmental benefit, through reductions in fuel burn for each flight, and increases in system effectiveness. The project will enable better analysis of Australian aviation environmental effect, whilst at the same time allowing the aviation industry to continue to contribute to Australia's sustainable economic growth.

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
