“…Australia has implemented water-sensitive urban design (WSUD) to solve the problem of urban water shortages caused by the vast differences in its national climate. From an urban master planning perspective, this design considers problems related to the hydrological cycle and water conservation measures before implementing regional planning and construction (Lloyd et al, 2002;Sharma et al, 2016;Ahammed, 2017).…”

The sponge city concept is a new strategy for China designed to solve its urban water problems. The tasks involved in sponge city construction (SCC) have brought new challenges regarding the urban construction process for local Chinese governments. However, there is still no comprehensive and systematic study of the government mechanisms for guiding the construction of sponge cities. This paper aims to develop an evaluation index system of government mechanisms at the whole-of-nation scale. This system covers five elements of government mechanisms. This evaluation index system covers the specific content of the government mechanism anticipated before the process of SCC. Since work systems, functions, and capacities differ with each given local government, the work mechanism of local governments can be adapted to local conditions according to the research results of this paper. By doing so it is possible to make full use of the constraint and management function of each indicator, so that all departments can constantly optimize the allocation of resources and clarify responsibilities, so as to effectively promote the construction of a sponge city.

“…In response to concerns regarding urban stream health and the impacts of stormwater flows, policies have been developed to ensure that stormwater running off all new developments is appropriately managed. In Australia, the resultant approaches are often referred to as Water Sensitive Urban Design (WSUD), which is a land use planning and environmental engineering approach to managing water more holistically in urban settings [7][8][9][10]. The philosophy focuses on the need to create water sensitive cities [11,12].…”

“…The state planning policy has set performance outcomes and design objectives for nutrient removal via stormwater management that provide minimum reduction requirements for total suspended solids, total phosphorus, total nitrogen and gross pollutants for WSUD stormwater assets [31]. While there are undoubtedly other benefits associated with stormwater treatment assets, including flood control, stormwater harvesting and biodiversity [10,17,23,26,27], the specific design objectives of interest in this study related to their role as treatment systems, which is the common focus of stormwater features in the US, Europe and Australia [17].…”

Community Perceptions and Knowledge of Modern Stormwater Treatment Assets

2020

Modern stormwater treatment assets are a form of water sensitive urban design (WSUD) features that aim to reduce the volumes of sediment, nutrients and gross pollutants discharged into receiving waterways. Local governments and developers in urban areas are installing and maintaining a large number of stormwater treatment assets, with the aim of improving urban runoff water quality. Many of these assets take up significant urban space and are highly visible and as a result, community acceptance is essential for effective WSUD design and implementation. However, community perceptions and knowledge about these assets have not been widely studied. This study used a survey to investigate community perceptions and knowledge about stormwater treatment assets in Brisbane, Australia. The results suggest that there is limited community knowledge of these assets, but that communities notice them and value their natural features when well-maintained. This study suggests that local governments may be able to better inform residents about the importance of these assets, and that designing for multiple purposes may improve community acceptance and support for the use of Council funds to maintain them.

“…Biofiltration systems, as one of the BMPs, have been well-practiced in developed countries such as the United States and Australia. Biofiltration systems have been found to be effective in improving the quality of stormwater runoff and managing runoff volume [2,6,[11][12][13][14][15]. Generally, a biofiltration system consists of a few layers of soil-based media with a different range of soil particles, which has vegetation on top.…”

Performance Assessment of a Laboratory Scale Prototype Biofiltration System in Tropical Region

Biofiltration systems, as one of the best management practices, have good potentials to improve stormwater quality and hydrology of urban catchments. While biofiltration systems are well-studied in developed countries, the majority of those studies are conducted for temperate climate and there is a lack of lab-scale and field-scale studies on such systems under tropical conditions. This paper focuses on the performance of a lab-scale prototype biofiltration systems in stormwater retention efficiency as well as pollutants removal (including heavy metals and nutrients) from synthetic stormwater reproducing tropical rainfall events. A three-layer sand-based filter media with two different native plants including Pedilanthus tithymaloides and Cyperus alternifolius was selected for this study. Results showed that the system with Cyperus has a better stormwater retention capacity compared to the one with Pedilanthus. In addition, the observed infiltration rate in Cyperus and Pedilanthus were 338 mm/h and 267 mm/h, respectively. The better hydraulic performance in the system with Cyperus was attributed to the deeper and more extensive root penetration of this plant (as deep as 800 mm) compared to Pedilanthus (as deep as 250 mm). While both systems failed to perform well in removing total nitrogen, they performed significantly better in removing total phosphorus (Cyperus and Pedilanthus removed 67.3% and 62.5% of total phosphorus, respectively). The statistical analysis of results showed that the top 100 mm layer of filter media is the main contributor to total phosphorus removal. However, no major differences were observed between the two systems in phosphorus removal. Moreover, both systems were also capable of removing the available heavy metals (i.e., Fe, Cu, Mn, Ni, Pb, and Zn) as the removal efficiencies exceeded 90%, except for Fe (76%). Similar to phosphorus, it was concluded that the top layer is the major contributor to the heavy metals removal. Overall, the biofiltration system using Cyperus was found to be a successful system for operating under tropical conditions.
