“…The appropriateness of this centralized and infrastructure-intensive approach which dominates the management of water supply and sewage disposal has been questioned over the past two decades [49]. As discussed earlier, there have been numerous proposals to address the shortcomings of the existing paradigm.…”

Abstract:The provision of a sustainable supply of water is an increasingly difficult task to achieve in many urban environments. This arises because of pressures related to population growth and increased per capita demand for water. Additionally, climate change is impacting the natural cycle of water in many locations, with a significant impact projected for the future. Many scholars advocate 'sustainable urban water management' (SUWM) as an approach that can address the root causes of these challenges. Yet the implementation of SUWM and adaptation to climate change in the urban water sector remains limited. This paper argues that spatial planning provides tools and processes that can facilitate the full implementation of SUWM goals, and adaptation to climate change. The potential of spatial planning to achieve SUWM, including sustainable urban water supply management through both supply and demand end initiatives, in light of climate change, is discussed. A framework is developed to consider a broad range of spatial planning interventions that can facilitate adaptation to climate change and SUWM concurrently. The paper provides information and tools to assist water planners achieve SUWM and a well-adapted water sector and urban environment, in an integrated, holistic and comprehensive manner, to meet future water supply needs. Achieving these goals will need collaborative activities across multiple built environment disciplines. Future research activities to advance these goals are outlined.

“…The DAnCE4Water model (Dynamic Adaptation for eNabling City Evolution for Water) began as part of the European Framework Program 7-'PREPARED enabling change' (www.prepared-fp7.eu) prior to the CRC for Water Sensitive Cities [86,99]. It was then adopted within Program A (Society) of the CRC for Water Sensitive Cities, where it evolved into a cloud-based city modelling platform.…”

“…It was then adopted within Program A (Society) of the CRC for Water Sensitive Cities, where it evolved into a cloud-based city modelling platform. Aspiring to be an interactive, 'user-friendly' decision support tool for different water actors to explore future scenarios and evaluate different policy and action strategies, DAnCE4Water takes into account the interactions between urban water infrastructure, the urban environment, and social dynamics [86]. This is represented by three modules rooted in a central unit, or 'conductor,' which runs each scenario by storing, managing and providing required data to the relevant modules [100].…”

Effort to narrow the gap between the production and use of scientific knowledge for environmental decision-making is gaining traction, yet in practice, supply and demand remains largely unbalanced. A qualitative study based on empirical analysis offers a novel approach to exploring key factors, focussing on seven water models in the context of two organisations at the science-policy interface: the PIREN-Seine in France and the CRC for Water Sensitive Cities in Australia. Tentative linkages drawn from these examples identify: (1) objective and expertise; (2) knowledge and tools; and (3) support structures as main drivers influencing the production of scientific knowledge which, in turn, affect the use and utility of modelling tools. Further insight is gained by highlighting the wide spectrum of uses and utilities existing in practice, suggesting that such 'boundary organisations' facilitate interactions and exchanges that give added value to scientific knowledge. Coordinated strategies that integrate inter-, extra-, and intra-boundary activities, framed through collaborative scenario building and the use of interactive modelling platforms, may offer ways to enhance the use and utility of scientific knowledge (and its tools) to better support water resources management, policy and planning decisions, thus promoting a more cohesive relationship between science and policy.

“…The urban water cycle is a complex system with a myriad of influential factors [8][9][10]. Towards system understanding [11], individual parts of the urban water cycle were examined (e.g., runoff scenarios can help decision makers to take appropriate action at an early stage to experiment with water policies that could support the management of an overstrained water supply in the future.…”

Conceptual Urban Water Balance Model for Water Policy Testing: An Approach for Large Scale Investigation

Urban water management will face various challenges in the future. Growing population in cities, changing climatic conditions and uncertain availability of water resources necessitate forward-looking water policy strategies. In this paper, we introduce a new water balance model to evaluate urban water strategies at a city scale. The aim is to evaluate decentralised water management measures within a large-scale investigation and to reduce external potable water demand. The upscaling process of local information (water demand, areal data) to a conceptual model approach is described. The modelling approach requires simplification of detailed processes to enable the execution with limited computing capacity. The model was applied to Greater Metropolitan Melbourne, Australia, a highly sprawled city with nearly four million inhabitants. Scenario analysis demonstrated the impact of using different water resources of different quality classes, the extensive implementation of water saving appliances and decentralised water storage strategies on the city's water balance. Results indicate a potential reduction of potable water demand of up to 25% with a conservative rainwater reuse and, even 60% with widespread implementation of rain-and greywater recycling. Furthermore, we demonstrate that even small systems implemented at a local level can have noticeable effects when operated as clustered schemes.
