The water-economy-innovation nexus is an integrated system that plays an important driving role in urban and regional sustainable development. To identify, evaluate, and measure the coupling-coordinated development of the regional water-economy-innovation nexus, this study selects China’s Grand Canal area as a typical case and constructs an integrated evaluation system of the water-economy-innovation nexus. Then, the coupling coordination model is used to evaluate the regional water-economy-innovation nexus’ development. Finally, grey correlation analysis is used to evaluate the influencing factors. The results find that the water-economy-innovation nexus’ overall development level is not high and that there are significant spatial differences. The coupling coordination level keeps rising, and the coupling coordination level of the central city is obviously better than other cities. Water accounts for the largest contribution to the coupling coordination of the water-economy-innovation nexus, followed by economy and innovation. This study contributes to the knowledge body of sustainable development and provides a scientific basis for the decision of coupling the development of the water-economy-innovation nexus in China’s Grand Canal area and other regions.Practical ApplicationsWater, as a fundamental resource, plays an important role in achieving the sustainable development goals (SDGs). However, water needs to interact with other factors to effectively achieve regional sustainable development. Innovation and the economy are both important drivers of sustainable development, and water is closely linked and interacted with them. Currently, the mechanism and extent of the coupled development of regional water-economy-innovation nexus remains unclear. To address this challenge, this study takes the Grand Canal area in China as a typical case and constructs an evaluation model with multiple methods to explore the coupling development of the regional water-economy-innovation nexus. This study verified the importance of multifactor coupling for regional sustainable development and demonstrated that water contributed the most, but the overall coupling development of the water-economy-innovation nexus was not high. Promoting the coupling development of the water-economy-innovation nexus through targeted policies is an important task for local governments.

3 Maximizing reliability is imperative for water distribution networks (WDN) design. Recent claims 4 about providing adequate and operable isolation valves as a focal aspect of a reliable WDN design 5 have attracted substantial interest. In this direction, this paper attempts to answer the question of 6 which isolation valves in a WDN must be prioritized based on their criticality towards enhancing 7 WDN reliability. Two novel algorithms are proposed – one for ranking every isolation valve in a 8 WDN and the second to identify the location of a new isolation valve to reduce the criticality of a 9 specific valve in a WDN. Unlike the prevailing methodologies, the proposed algorithms are 10 entirely based on the topological attributes of a WDN and do not require a calibrated hydraulic 11 model, which is often a limiting factor in WDN management. Our proof-of-concept has unveiled 12 the capability of the methodology to deliver preliminary information to water utilities regarding 13 the criticality of valves without any hydraulic simulation.

Some recent studies have used actual water end-use data to inform the peak demand design of plumbing systems in residential buildings, addressing the problem of overestimation in many long-standing plumbing codes and standards. Vast amounts of fixture-specific data from each household are required to determine the frequency each fixture is used during peak water consumption periods (fixture-use probability). However, obtaining such data can be difficult, and the processing is costly and time-consuming. The current study presents a new approach for determining the fixture-use probability for peak water demand design of premise plumbing systems. A stochastic water demand model is developed using only the high-level statistical information from water end-use studies presented in the public domain, offsetting the need for the original water end-use data sets. The stochastic model is then used to form easy-to-use formulas for determining the probability of use for various fixture groups, which consider both the number of apartments and building occupancy. The approach is validated by comparing the estimated peak demand values with the corresponding values determined from actual water consumption observations in three Australian residential apartment buildings and one mixed-use building. The new approach enables a much more accurate estimation of the peak demand compared with the conventional approach suggested in the current Australian plumbing standard. The proposed approach can be used by researchers and practitioners in other countries to determine their region-specific fixture-use probability values for more accurate peak demand estimation, contributing to improved premise plumbing system design.

Lack of access to potable drinking water is a crucial problem faced by many communities globally, especially poverty-stricken rural regions and urban and peri-urban settlements. Consumption of contaminated drinking water leads to both chronic and acute health consequences, especially in the case of young children and immunocompromised individuals. The sixth UN Sustainable Development Goal (SDG) seeks to provide universal access to safe drinking water by the year 2030. Household water treatment systems (HWTSs), such as membrane filters and chlorination tablets, have been researched and proposed as solutions for water treatment in developing economies for decades because they can provide localized solutions that best fit the context of the community of intervention. Despite increased resources, funding, and effort, many HWTSs fail long-term, sustained implementation in developing economies. This study takes a holistic approach, considering factors from both the technical and operational environment to identify factors and circumstances that inhibit these treatment technologies. Results from an analysis of 30 articles show that studies predominantly focus on factors related to system design and performance (e.g., contaminant removal efficacy, system flow rate, impact of turbidity). Many studies also focus on factors surrounding user perception and behavior. Factors with lower coverage in the data set relate to operation and maintenance, financial sustainability, supply chain, and the legal and regulatory structures. These findings are situated within a holistic conceptual framework that serves as a resource for knowledge transfer and can be updated to fit a variety of contexts.
