Water is precious, and increasingly scarce. Many Australians – householders, businesses, farmers, those concerned about sustainability and the environment, among others – have diverse preferences about water allocation. Yet the operating rules that water supply system managers currently use were designed when water was comparatively plentiful. This project will assist system managers to develop contemporary rules for water allocation decision-making. A case study of the Grampians headworks system in Victoria will provide the opportunity to trial methods that account for diverse stakeholder preferences in the context of climate change and climate variability, including drought events.

Optimal scheduling of urban bulk water systems under uncertainty. This project will develop a new optimisation framework for planning and operation of urban bulk water systems that incorporates flexibility to adapt to changing circumstances. Population growth in major Australian cities, coupled with a potentially drying climate, is putting pressure on existing water supply. To avoid the risk of overinvesting and losing future flexibility, water utilities have to develop plans for the future, a t ....Optimal scheduling of urban bulk water systems under uncertainty. This project will develop a new optimisation framework for planning and operation of urban bulk water systems that incorporates flexibility to adapt to changing circumstances. Population growth in major Australian cities, coupled with a potentially drying climate, is putting pressure on existing water supply. To avoid the risk of overinvesting and losing future flexibility, water utilities have to develop plans for the future, a task made difficult by uncertainty about future climate and demand. The framework is intended to explicitly deal with uncertainty about future demand and climate change, to ensure that solutions can cope with plausible but unexpected futures. The project will apply this framework to the bulk water supply for Sydney.Read moreRead less
Combining transient micro-reflections and multi-sensor arrays for condition assessment of buried pipes. This project will develop an accurate and reliable approach for assessing the condition of pipelines. This new approach will reduce costs and save considerable amounts of water each year, as it will assist utilities in preventing major failures such as pipe bursts, and performing strategically targeted maintenance, replacement and rehabilitation.
Detecting developing cracks before pipe bursts using smart sensor systems. This project aims to significantly reduce the number of pipe bursts in cities by detecting the leaks from developing cracks on water supply pipes just in time. New techniques will be developed for reliable and timely detection using the existing sensor network in the Adelaide CBD. Specialised monitoring stations will be developed with adaptive noise-cancellation algorithms to detect small leak signals in noisy city enviro ....Detecting developing cracks before pipe bursts using smart sensor systems. This project aims to significantly reduce the number of pipe bursts in cities by detecting the leaks from developing cracks on water supply pipes just in time. New techniques will be developed for reliable and timely detection using the existing sensor network in the Adelaide CBD. Specialised monitoring stations will be developed with adaptive noise-cancellation algorithms to detect small leak signals in noisy city environments. Expected outcomes include an effective pipe burst early warning system and the implementation of an active burst prevention and targeted pipe replacement strategy. This should significantly reduce the burst rates and associated interruptions in Adelaide and save millions of dollars every year in pipe relay programs.Read moreRead less
Cost Effective Pipeline Condition Assessment Using Paired Pressure Sensor Arrays. Water distribution networks represent society's most important infrastructure asset. They are buried pipes and are often old and deteriorating. Cost-effective methods to assess their physical condition are urgently needed. This research will develop a novel and advanced approach to determine the interior condition of pipes quickly and effectively using small water hammer pulses or waves. Paired pressure sensor arra ....Cost Effective Pipeline Condition Assessment Using Paired Pressure Sensor Arrays. Water distribution networks represent society's most important infrastructure asset. They are buried pipes and are often old and deteriorating. Cost-effective methods to assess their physical condition are urgently needed. This research will develop a novel and advanced approach to determine the interior condition of pipes quickly and effectively using small water hammer pulses or waves. Paired pressure sensor arrays will be used to measure reflections of the waves in pipes and these methods will enable finer resolution and identification of pipeline faults, such as wall thickness loss and leakage while at the same time allowing operational continuity. The outcome will be powerful tools to more cost effectively manage these crucial assets.Read moreRead less
High-resolution pipeline condition assessment using hydraulic transients. This project aims to develop urgently needed non-invasive methods to assess fine detail of a pipe’s condition and allow ‘just in time’ predictive repair. Water distribution networks are society's most important infrastructure asset. They consist of buried pipes that are often old and deteriorating, and annual maintenance overhead exceeds $1 billion per year in Australia alone.

Water distribution networks are society's most important infrastructure asset. They consist of buried pipes that are often old and deteriorating, and annual maintenance overhead exceeds $1 billion per year in Australia alone. The project will develop cost-effective powerful tools to identify faults, such as pipe wall corrosion and blockages, while allowing operational continuity. The expected outcome is high-resolution images of wall condition of pipes using high-frequency pressure transients and sophisticated fibre optic sensor arrays.Read moreRead less

Resilient design flood estimation for Australia. The total costs of natural disasters in Australia are forecast to more than double in the next 20 years - with floods one of the costliest natural disasters faced. The damage and cost of floods can be managed, but rapid developments in the understanding of rainfall and flood projections has resulted in national flood guidelines that are not consistent with current science. This project proposes a novel but practical technique for design flood esti ....Resilient design flood estimation for Australia. The total costs of natural disasters in Australia are forecast to more than double in the next 20 years - with floods one of the costliest natural disasters faced. The damage and cost of floods can be managed, but rapid developments in the understanding of rainfall and flood projections has resulted in national flood guidelines that are not consistent with current science. This project proposes a novel but practical technique for design flood estimation that will accommodate the key changes to flood behaviour that are expected in the future. This will include consideration of changes in extreme rainfall intensities, catchment wetness, and patterns of storm behaviour.Read moreRead less
