Adoption Guidelines for Green Treatment Technologies

Abstract To increase the resilience and liveability of cities and to maintain their productivity, green infrastructure is being highly viewed as a sustainable development strategy. Green infrastructure or technologies, essentially, represent a set of engineered elements providing multiple ecosystem services…

The most cost-effective ways to maintain public open space with less water

Reduced irrigation water available for public open space (POS) due to groundwater depletion is an emerging problem in many urban areas. Local governments in Perth face mounting pressure to maintain high quality POS while being driven to use less groundwater…

Influence of pressure main pumping frequency on sulfide formation rates in sanitary sewers

Abstract Reductions to hydraulic flows in sewer networks resulting from water conservation and re-use strategies will change the operational behaviours of our existing sewer infrastructure. For intermittently flowing pressure mains, changes to the duration and frequency of pumping events effect…

Storm event-scale nutrient attenuation in constructed wetlands experiencing a Mediterranean climate: A comparison of a surface flow and hybrid surface-subsurface flow system

Abstract Among different Water Sensitive Urban Design (WSUD) options, constructed wetlands (CWs) are widely used to protect and support downstream urban waterways from stormwater nutrients. This analysis assessed the nutrient attenuation ability of a novel CW in Western Australia that…

Framework for the optimization of operation and design of systems with different alternative water sources

Abstract Water security has become an increasing concern for many water system managers due to climate change and increased population. In order to improve the security of supply, alternative sources such as harvested stormwater, recycled wastewater and desalination are becoming…

Sensor placement strategy for locating leaks using lean graphs

Abstract Undetected leaks in water distribution networks are a significant economic and environmental problem worldwide. Small leaks are hard to detect yet they contribute significantly to water losses. We propose a method to detect small leaks using a leak signature,…

Comparison of Pumping Regimes for Water Distribution Systems to Minimize Cost and Greenhouse Gases

Abstract A single-objective optimization model has been developed for water distribution system (WDS) pumping operations, considering five different types of pump operating regimes. These regimes use tank trigger levels, scheduling, and a combination of both to control pumps. A new…

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…

SeweX modelling to support corrosion and odour management in sewers

Abstract Sewer corrosion and odour problems are common worldwide. The annual cost of rehabilitation of corroded sewers and other mitigation actions was estimated at hundreds of millions of dollars in Australia alone. This cost is likely to increase as the…
