Global Population

As projections highlight that half of the global population will be living in regions facing severe water scarcity by 2050, sustainable water management policies and practices are more imperative than ever. Following the Sustainable Development Goals for equitable water access and prudent use of natural resources, emerging digital technologies may foster efficient monitoring, control, optimization, and forecasting of freshwater consumption and pollution. Indicatively, the use of sensors, Internet of Things, machine learning, and big data analytics has been catalyzing smart water management. With two-thirds of the global population to be living in urban areas by 2050, this research focuses on the impact of digitization on sustainable urban water management. More specifically, existing scientific literature studies were explored for providing meaningful insights on smart water technologies implemented in urban contexts, emphasizing supply and distribution networks. The review analysis outcomes were classified according to three main pillars identified: (i) level of analysis (i.e., municipal or residential/industrial); (ii) technology used (e.g., sensors, algorithms); and (iii) research scope/focus (e.g., monitoring, optimization), with the use of a systematic approach. Overall, this study is expected to act as a methodological tool and guiding map of the most pertinent state-of-the-art research efforts to integrate digitalization in the field of water stewardship and improve urban sustainability.

Abstract. The global population is increasingly concentrated in cities. Cities and urban areas face many challenges – economic, social, health and environmental – which are often exacerbated by an increase in the frequency of natural disasters. Together, these challenges call for a shift towards sustainable cities which reduce their impact on the surrounding environment, whilst at the same time succeeding to make resources available to their increasing number of inhabitants. This article explores the state of the art of water management practices of the highly urbanised Northern Italian region and plans and scope for the future development of water management. Although the region is at present not under severe water stress, recently some cities faced water scarcity problems and were forced to implement water rationing. We assessed the vulnerability of Parma and Ferrara to a water crisis, together with the regular and emergency adaptation measures already in place, and the forecast for the near future. In two workshops, the authors adapted the Australian concept of Water Sensitive Urban Design for the Italian context. Although the population remains generally unaware of the impact of the two latest severe drought events (2003 and 2006/7), many adaptation measures towards a more sustainable use of the water resource are already in place – technically, institutionally, and individually. Water managers consider however that the drastic and definite changes needed to integrate the urban water management cycle, and which minimise the ecological footprint of urban spaces, lay far in the future.

<p>Nature-based solutions have the potential to provide a wide range of essential ecosystem services as well as water management goals. As the majority of the global population lives in cities, NBS for addressing water management in urban areas is of great importance. Despite the recent advances and growing experiences with the implementation of NBS, there is still below 1% of the total investment in water resource management infrastructure that is dedicated to NBS in urban areas? One of the current obstacles for implementation is the lack of knowledge, data and information about the design and implementation of NBS for water management. Although there has been a growing interest in NBS in recent years, there are still a large need for a comprehensive evidence based on the effectiveness of NBS. Therefore, there is also a need for monitoring both the process of implementing NBS as well as the outcomes, including the final benefits of the NBS<strong>, </strong>how the NBS is perceived and how it responds to the challenge for which it was implemented.  The aim of this study is to assess the effectiveness of nature-based solutions (NBS) for urban resilience in particular for water management in different climate zones, focusing on cities that have worked or are planning to work extensively with NBS. This study explores which opportunities and barriers current regulatory frameworks and management practices imply and how the former can be reaped and the latter overcome, for implementation of effective NBS. The study focuses on the analysis of available data bases of NBS in different cities This study also creates an inventory of indicators used to assess the NBS effectiveness, covering a range of social, economic and technical aspects.</p>

The Impact

With the growth of urban areas and climate change, decisions need to be taken to improve water management. This paper reports an assessment of the impact of greywater recycling systems on catchment scale hydrological flows. A simulation model developed in InfoWorks CS (Wallingford Software Ltd) was used to evaluate how river flows, sewer flows, surface runoff and flooding events may be influenced when grey water recycling systems of different number and scale are implemented in a representative catchment. The simulations show the effectiveness of greywater recycling systems in reducing total wastewater volume and flood volume. However, no hydraulic impacts due to implementation of greywater was identified by the model.

Related to water resources is one of the problems that often occurs in certain areas that have large populations such as urban areas, in addition to having to provide water that is used for daily activities, today many urban residents live in urban hardships, so an alternative is needed in providing resources water that must be purchased in daily necessities, in this paper we proposed a framework for support urban farming that we called the smart water management system by utilizing the IoT (Internet of Thinks) technology specifically sensors and machine learning algorithms in managing available water resources. many researchers have developed a similar model, but the framework model that we proposed using reuse water and filtered rainwater so that it meets the minimum quality requirements of water that can be reused in agriculture, so we hopes to make domestic water use more effective and efficient and predictable water consumption and availability.

Water Metering

Sustainable water management is increasingly essential in an age characterised by rapid population growth, urban and industrial development and climate change. Opportunities to promote conservation and water-use efficiencies remain attractive in directly reducing water demand. Smart water metering and the provision of detailed water-use feedback to consumers present exciting new opportunities for improved urban water management. This paper explores two smart water metering trials in New South Wales, Australia, which provided household water consumption feedback via (i) paper end-use reports and (ii) an online portal. This combination enabled a deeper exploration of the various impacts of detailed feedback enabled via smart water metering. The positive effects uncovered by the research present an important opportunity for smart water metering feedback to contribute towards more sustainable urban water management. Their summary contributes empirical evidence on the impacts for water utilities considering embarking on the smart water metering journey with their customers. The identification of future research and policy needs sets an agenda for smart water metering to promote a sustainable digital urban water future. Larger-scale trials are now required and utilities should integrate the design and plans for scalable advanced feedback programs at the outset of smart meter implementations.
