“…This approach allows the identification of failures that pose the greatest threat to the safety of water supply to consumers. The surveys show that the time of lack of water supply is one of the most important parameters for water consumers [60]. Detailed knowledge on the causes of the water network failures can be used to plan replacement or renewal of pipes.…”

The water distribution subsystem is the most failing subsystem included in the water supply system. One of the main consequences of water supply failures is the lack of water supply to consumers, which is always very onerous. The paper presents a method of determining the conditional probability that a break in the supply of water to consumers of a certain duration will be caused by a specific type of failure. The result of the work was to identify water supply network failures that result in the longest water supply suspension time. The method was presented on a real water supply system. In order to reduce the incidence of long-term interruptions in water supply, water supply companies should mainly continue replacing gray cast iron pipes with thermoplastic materials. Actions taken to increase the safety of drinking water supply meet the current standards for the safety of drinking water, developed by the World Health Organization and the European Union.

“…Second, the control variables in the model can be further adjusted or expanded according to the new research. Third, the consumers’ perceptions of the supply of tap water could facilitate management by water companies and help to protect different groups of recipients that secure services of appropriate quality in the implementation of water rights trading; thus, the research perspective can be further expanded to the consumers’ perceptions of the supply of tap water [ 27 ]. Last, the “third-party effect” of water rights trading has been raised by some researchers [ 28 , 29 ], which refers to the fact that people or institutions other than the transferor and receiver of water rights may suffer losses or gain benefits in the process of trading.…”

Using the panel data of 30 provinces in China from 1998 to 2017, we adopt a time-varying difference-in-differences (time-varying DID) model to estimate the impact of water rights trading scheme on regional water consumption. The results show that water rights trading can significantly promote water conservation in the pilot regions by 3.1% compared to that in the non-pilot regions, and a series of robustness tests show consistent results. Policy effects are mainly driven by improving water-use efficiency and adjusting water structure; that is, by transferring water resources from the agricultural sector to the other sectors, agricultural water efficiency is improved and water conflict among sectors is alleviated; thus, water saving is achieved. In addition, by constructing two indexes of regional water pressure and tradable water resources, our heterogeneity analysis shows that water rights trading performs better in areas with high water pressure and large tradable water resources. Under the high pressure of large water use and low water endowment, water rights trading will evidently reduce water consumption more so than in the low-pressure regions, and with water rights trading, it is hard to achieve a policy effect in regions without sufficient tradable water resources. This paper provides important policy implications for China for further promoting the water rights trading scheme in the field of resource conservation.

“…Crouch et al [8] studied the absolute basic consumption of individuals and developed a 21-item theoretical model that randomly describes individual water use activities based on the lifestyle level of Maslow's physiological demand hierarchy, which was applied to the formulation of strict water restriction policies. In addition, the security of water consumption also depends on the construction of well-established water networks and high-quality water services [9,10]. Meanwhile, foreign scholars rely on the micro data of families to analyze the utilization of water resources.…”

Mechanism Study on the Impact of China Population Structure Change on the Water Use of the Three Main Industries

et al. 2021

As the principal part of economic and social development, the demographic factor is the fundamental factor driving the change of water resources, and achieving the harmony of human and water has been one of the most important tasks to promote high-quality development. Based on Maslow’s hierarchy of needs theory, this article applied panel data for 19 years and employed impulse response functions and threshold models to do a mechanism analysis of the impact of population structure changes on the water consumption changes of the three main industries. The study found the following: Firstly, the urban population promotes an increase of the total water consumption, industrial water consumption, and domestic water consumption, which suppresses agricultural water consumption and shows an inverted “N” trend. Secondly, the aging population has expanded the total water consumption, and agricultural and domestic water demand, and reduced industrial water consumption. Thirdly, food consumption helps to reduce the total water consumption and agricultural water consumption, but increases the industrial water consumption and the growth rate rises. Fourthly, the increase in the proportion of agricultural employment reduces the total water consumption, and agricultural and domestic water consumption, and increases industrial water consumption. Fifthly, the total water consumption and domestic water consumption both increase with the improvement of the population education level, while the agricultural water consumption declines first and then rises. The empirical results can provide a reference for analyzing the driving mechanisms of regional water consumption changes.
