Integrated Urban Water Management

Climate change along with industrialization or urbanization, which uses materials with low water permeability and is accompanied by change in urban land use, are major reasons for frequent urban floods in many Chinese cities. Moreover, upgrading the drainage system can have numerous negative environmental impacts on the city, especially in districts with dense population and buildings. A new integrated urban water management (IUWM) strategy implemented in China, “sponge city,” has gained significant attention in recent years. In this study, a novel framework is built to analyze the effectiveness of sponge city by 3D simulating urban inundation results and performing a cost–benefit analysis. Construction and maintenance fees are included in the costs list, and carbon reduction, air quality improvement, rainwater harvesting, and reduction of flood risk are included under benefits. The district of Nangang in Harbin city in Northeast China was chosen as a case study area. Finally, we conclude that the maximum precipitation of 49.82 mm/h by sponge city can bring the inundation depth below a target depth in the target area. Further, though the sponge city project is not effective from a private perspective, it is effective from a social perspective.

Sustainable Urban Water Management

Sustainable, resilient urban water management is fundamental to good environmental and public health. As an interdisciplinary task, it faces enormous challenges from project complexity, network dynamics, and the tacit nature of knowledge being communicated between actors involved in design, decisions and delivery. Among others, some critical and persistent challenges to the implementation of sustainable urban water management include the lack of knowledge and expertise, lack of effective communication and collaboration, and lack of shared understanding and context. Using the Chinese Sponge City programme as a case study, this paper draws on the perspectives of Polanyi and Collins to investigate the extent to which knowledge can be used and exchanged between actors. Using Collins’ conceptualisation of the terrain of tacit knowledge, the study identifies the use of relational, somatic, and collective tacit knowledge in the Sponge City pilot project. Structured interviews with 38 people working on a Sponge City pilot project provided data that was rigorously analysed using qualitative thematic analysis. The paper is original in using theories of tacit knowledge to explain barriers and pathways for information and messages being communicated between actors in urban water management. The methods and results provide the groundwork for analysing the access and mobilisation of tacit knowledge in the Sponge City pilot project, with relevance for other complex, interdisciplinary environmental projects and programmes.

Integrated Urban Water Management

Singapore is an exemplary model of integrated water management, according to the World Health Organization, and its experiences can be shared with others. Water security is not just the government's responsibility but has become everyone's business. Singapore has been selected as a case study for integrated urban water management (IUWM), and the methodologies used in Singapore, a developed city state, may be applicable elsewhere. An integrated regulatory framework, sound policies to control and implement programmes, public-private partnership in water services delivery, and stakeholder participation at all levels are necessary to make integrated water resource management successful. This paper demonstrates how Singapore has successfully turned its vulnerability with regard to water into a strength. Singapore can achieve greater sustainability if it promotes rooftop rainwater harvesting as a decentralized, dual-mode water supply system for non-potable use.

Integrating sustainable urban water management into the urban planning process is essential for developing water-resilient cities. To this end, the central government of the People’s Republic of China initiated the “Sponge City” programme. However, challenges and gaps exist in current urban planning practice. The operationalizable planning approach to realise the multiple objectives of Sponge City is missing in the existing guidelines. Using a local example of Sponge City planning in Nanjing City as a case study, this paper outlines the current Sponge City approach from the perspectives of planning content and planning process. A qualitative comparative analysis between Nanjing’s Sponge City planning and Auckland Water Sensitive Design, as well as an evaluation of the Sponge City approach through the lens of Dutch urban water management, identified key missing elements that would enhance the current Sponge City planning approach. Examples include targets for pluvial flood protection, a strategy for planning interventions, and tools for interdisciplinary cooperation in the planning process. This enhanced approach was successfully applied in the Sponge City planning for Qinhuai District, Nanjing City. Nevertheless, challenges on data availability and the decision-makers’ mindsets called for more efforts on the interface of research and policy development for upscaling the Sponge City approach.
