“…For situations where there is a lack of drinking water security management, it is proposed that water source protection and risk prevention be strengthened and water supply security ensured. Here, enhancing the equipment for projects, modulizing systems of devices, developing instrumentation for management systems, and establishing intelligent water management platforms of drinking water security protection are achieved through collection strategies of engineering, technology, and management so as to advance the Urban and Rural Drinking Water Security Project in Northwest China [5]. …”

China has paid more attention to improving urban and rural drinking water security in recent years. Ensuring the security of drinking water in urban and rural areas is a fundamental condition for protecting the basic interests of the public, and it is also an important aspect of building a moderately and all-sided prosperous society in China. Taking the Shanshan County in Turpan City of Xinjiang Autonomous Region as an example, this study analyzed the countermeasures of ensuring drinking water security. Firstly, this paper discusses the status quo of drinking water security in Shanshan. In terms of urban drinking water, problems are shown as follows: (1) drinking water sources are polluted to varying degrees; (2) water treatment technologies lag behind when compared to the social development; (3) there is a high leakage rate in the water supply pipe network; and (4) there is low emergency handling capability. In terms of rural drinking water, smallscale drinking water security projects are on low construction standard, which has resulted in low water supply guarantee rates and poor water source protection and water quality supervision. Secondly, based on an analysis of current problems, the quantity of water resources guaranteed is put forward. This paper divides Shanshan County into three units-the Karuqi area, the Ertanggou area, and the Kekeya area-based on urban or rural land use. This paper proposes the optimal distribution of regional water plants and a water supply network for the optimal allocation of regional water resources. Thirdly, for water quality improvement, a corresponding water purification program is developed to solve raw water quality problems, which includes centralized and decentralized water quality treatment, as well as an intelligent water flow control process. At the same time, management measures such as water source conservation and risk control measures are proposed in order to promote the security of drinking water. This paper also puts forward relevant strategic suggestions for ensuring the security of drinking water in Shanshan County, which includes enhancing equipment for the project, modulizing the system of devices, developing instrumentation of the management system, and establishing an intelligent water management platform. This study acts as a reference for solving problems of drinking water security in urban and rural areas in arid regions in Northwest China and similar areas around the world.

“…Many studies have been conducted in which the performance of water supply PIs were used to assess the performance of a water supply system in terms of its efficiency and effectiveness. PIs are tools for evaluating the efficiency, effectiveness, and robustness of water supply systems, and they can help decision-makers develop safe and reliable infrastructure strategies based on past and present trends [21] (see also [22] [23] [24]). The PI system in Japan consists of an excessive number of items, and principal component analysis was used to reduce the dimensionality of the original data [25].…”

Japan has experienced many large-scale natural disasters, such as earthquakes, typhoons accompanied by heavy rain, and landslides. Based on data for the damage caused by four recent major earthquakes in Japan, we investigate the trends in the number of evacuees and evacuation centres after these disasters as well as the restoration processes for public utilities such as electricity, gas, water, and communication lines. We compare the restoration speeds and trends of the damaged infrastructure systems. We also propose various mathematical models to approximate the recovery trends using both evacuee-related data and damage recovery process data. These results can be used to design natural disaster mitigation policies not only in Japan, but also in other countries. The results of various statistical data analyses and mathematical modelling techniques are applied to provide policy suggestions.

“…Hoekstra et al (2018) discuss the transition from language around integrated and sustainable water management, into the new language of water security. While other reviews note the absence of any definitions or clarifications of language (Clement 2013;Cook and Bakker 2016), even when reporting on research into complex water security assessment and modelling (Nazif et al 2013;Esmail and Geneletti 2017).…”

Urban water security - what does it mean?

This research is focussed on understanding what urban water security means -a surprisingly elusive concept given the global shift from rural to urban living. We first make the case for a distinct urban water security definition. We then identify 25 unique water security definitions, of which three relate to the urban context but all with scope for improvement. Applying novel indices, we assess the prevalence, complexity and evolution of themes and dimensions within all definitions and find a stable spectrum of themes; but note a shifting emphasis towards environmental and social dimensions, away from quality and quantity of supply. Overall the definitions are becoming more comprehensive by simply listing more outcomes to be achieved. Instead of this 'shopping-list' approach, we propose a simplified urban water security definition with a focus on agreement of needs with community stakeholders, while using the themes to guide what the objectives might be.
