Green walls for greywater reuse: Understanding the role of media on pollutant removal

Abstract Green walls offer multiple benefits to urban environments, but they are major water consumers and not optimal for use in dry climates. If green walls were engineered to treat greywater, they could become cost-effective and more widespread. However, it…

Pesticide occurrence and spatio-temporal variability in urban run-off across Australia

Abstract Stormwater is a major driving factor of aquatic ecosystem degradation as well as one of the largest untapped urban freshwater resources. We present results from a long-term, multi-catchment study of urban stormwater pesticides across Australia that addresses this dichotomous…

Water in the city: Green open spaces, land use planning and flood management – An Australian case study

Abstract With increasing worldwide recognition of the influence of urban development on the hydrological functions of water, there is growing pressure for urban planning to play a greater role in water resources management. Planning for green open spaces in particular…

The interaction of risk allocation and governance arrangements in innovative urban stormwater and recycling projects

Abstract Successful innovation requires clarity around the identification and allocation of risk and the responsibilities of stakeholders in its management. The quest for water security in large cities has led to consideration of alternative water sources, which may involve new…

The Impact-Likelihood Matrix: A policy tool for behaviour prioritisation

Abstract The proliferation of applied behaviour change science over the past decade has provided new ways of thinking about policy making. Policy makers now have a range of frameworks and methods to assist in formulating change for social and environmental…

Development of an integrated software tool for strategic planning and conceptual design of water sensitive cities

Abstract The management and use of water in urban environments to provide resilience to climate change is an increasingly critical challenge for cities and towns in Australia, and globally. Current trends of growing urban populations and increased urban densities heighten…

Innovation for rapid denitrification in biofiltration systems

Abstract Biofiltration systems are an effective technology for removal of nitrogen from stormwater. It has recently been proposed to harness these systems for treatment of other water types (such as light wastewater and polluted groundwater) during dry weather periods. Light…

Phosphorus Fate and Dynamics in Greywater Biofiltration Systems

Abstract Phosphorus, a critical environmental pollutant, is effectively removed from stormwater by biofiltration systems, mainly via sedimentation and straining. However, the fate of dissolved inflow phosphorus concentrations in these systems is unknown. Given the growing interest in using biofiltration systems…

Designing living walls for greywater treatment

Abstract Greywater is being increasingly used as an alternative water source to reduce potable water demand and to alleviate pressure on sewerage systems. This paper presents the development of a low energy and low maintenance greywater treatment technology: a living…

Evaluation of sustainable electron donors for nitrate removal in different water media

Abstract An external electron donor is usually included in wastewater and groundwater treatment systems to enhance nitrate removal through denitrification. The choice of electron donor is critical for both satisfactory denitrification rates and sustainable long-term performance. Electron donors that are…

Determination of operational and challenge conditions for validation of stormwater biofilters and wetlands

Abstract In Australia, guidelines have been developed for the validation of engineered treatment processes. However, these guidelines do not prescriptively address validation of passive water sensitive urban design (WSUD) treatment systems. The first step in developing validation guidelines for WSUD…

Taking the “waste” out of “wastewater” for human water security and ecosystem sustainability

Abstract Humans create vast quantities of wastewater through inefficiencies and poor management of water systems. The wasting of water poses sustainability challenges, depletes energy reserves, and undermines human water security and ecosystem health. Here we review emerging approaches for reusing…

Validation framework for water-sensitive urban design treatment systems

Abstract Treatment of urban stormwater is common practice in Australia (Hatt et al., 2006), for protection of either downstream ecosystems or human health prior to harvesting and reuse. We have adopted a mixture of techniques to reduce stormwater's highly variable…

Methodologies for Pre-Validation of Biofilters and Wetlands for Stormwater Treatment

Abstract Background Water Sensitive Urban Design (WSUD) systems are frequently used as part of a stormwater harvesting treatment trains (e.g. biofilters (bio-retentions and rain-gardens) and wetlands). However, validation frameworks for such systems do not exist, limiting their adoption for end-uses…
