Urban Water Management

Urban water management remains a complex interplay between climate change, population growth, water scarcity, and the living environment. This agenda has called for an integrated, coordinated, ecologically-oriented, and participatory approach to the reliable protection of water resources. Malaysia, endowed with its rich natural resources and diversity recognizes the need to adopt a sound developmental framework to transform the country's water management landscape to a high quality and excellent level. In parallel with this development, both government and non-governmental organizations continue to advocate national efforts to address environmental research for incorporating the sustainability of environmental literacy and conservation of ecosystems. The plan espouses the establishment of urban water recycling, bio-retention systems, and constructed wetlands to buffer the impacts of water pollution, and preserve ecosystems for the neighboring communities. The impetus is accompanied by the integration of water quality monitoring systems, and boosted by the implementation of expert analysis. The present work attempts to address the dynamic pressure, key challenges, and benefits of urban water management practices in Malaysia. The sustainable concepts of waterfronts, constructed wetlands, and implementation of water monitoring analysis are elucidated. In addition, the research breakthroughs, major obstacles, and co-operative ventures for the promotion of urban water management are outlined.

Planning And Construction

Urban constructed wetland, effectively used in sewage disposal and ecological restoration, has unique advantages in urban ecological construction. With the development of the ecological landscape concept, constructed wetland gradually has become an important urban ecological landscape. Based on ecological concepts, ecological principle, technical principle and aesthetic principle of planning and the layout, process, landscape, plants and other key issues of design were discussed for the constructed wetland. In this paper, taking Zhongxiang City, Jingmen, Hubei Province as an example, the treatment technology, functional layout and ecological landscape of constructed wetlands were designed based on the analysis of location and site. Through the planning and construction of constructed wetlands, the quality of urban water environment would be improved and the urban water environment with the characteristics of Zhongxiang would be formed, promoting the urban construction to be more green, ecological and livable.

System A

This paper presents a comparative analysis of 5 systems for the treatment of greywater for reuse. The systems investigated were a biological system: a membrane bioreactor (MBR), a chemical system: a membrane chemical reactor (MCR) and three constructed wetlands: vertical (VFRB) and horizontal (HFRB) flow reed beds and a green roof (GROW). The results revealed that the GROW and the HFRB achieved a limited treatment of the greywater. Alternatively, the MBR, the MCR and the VFRB achieved a good general treatment of the greywater. However, the MBR and MCR alter more significantly the solids and microbial fractions. Overall, the MBR was found to be the most suitable technology for greywater recycling due to its robustness. Indeed, the MBR constantly achieved an excellent treatment of the high strength greywater.

Surface Flow Constructed Wetlands

GIS-based approach to find the suitable sites for surface flow constructed wetlands was employed for the Lithuanian river basins with low ecological status. According to the nature of the analysed criteria the flowchart consists of two phases. Criteria used include hydrographical network, soil properties, terrain features, land use, etc. Some of them have strictly defined values (constraints), and other ranges within certain limits (factors). Limited criteria were analysed using rejection principle and influencing factors using proximity analysis and overlay methods. Selecting the potential sites using standard GIS analysis tools there was estimated about 3286 sites for possible wetlands with the mean area of inflow basin about 4 km2 in the basins of water bodies at risk.
