“…Therefore, unavailable data in this phase can significantly influence the results. For instance, focusing on the materials and neglecting part of the energy required for pipe manufacturing, Piratla et al (2012) concluded that the CO 2 emissions from the embodied energy of PVC were higher than those associated with DI pipes, which contrasts with the findings of other research (Sanjuan-delmás et al 2014;Hajibabaei, Nazif, and Sereshgi 2018).…”

“…They concluded that the amount of CO 2 emissions released in the production phase of polyvinyl chloride (PVC) pipes was higher than that associated with ductile iron (DI). However, in other publications, the impacts of the production of 200 mm DI pipes regarding the global warming category were found to be around four to six times higher than those associated with PVC pipes (Sanjuan-delmás et al 2014;Hajibabaei, Nazif, and Sereshgi 2018).…”

Applying life cycle assessment (LCA) to water distribution networks (WDNs) usually requires considerable reliable data, and neglecting specific parts could significantly affect the reliability of results. In this paper, a comprehensive life cycle inventory dataset was collected to evaluate the environmental burdens associated with the construction and renovation stages of WDNs. The aim is to explore the effects of the availability of primary and secondary data on the LCA results based on analysis of uncertainties. The results indicate the importance of considering road construction processes, especially for small-tomedium-sized plastic pipes. Although recovering energy from the incineration of plastic pipes partially compensates for the impacts at the end of life, these incineration processes significantly affect the global warming potential. Finally, this study demonstrates that without considering all known information (e.g., network data), reliable LCA for WDNs can be performed, providing suggestions on which data to focus on in data collection process.

“…The increasing level of urbanisation has led to an increase in the scale of water supply pipelines constructed in urban areas [ 1 ]. Owing to obsolete water supply infrastructures, complex maintenance operations in densely populated areas, and high maintenance costs, the leakage rate of water supply networks has reached 25% [ 2 ].…”

Leakage detection methods based on the analysis of leakage acoustic signals provide an effective technical approach for detecting small leaks in water supply pipelines. From a technical perspective, the study of the propagation characteristics of acoustic waves generated by the leakage in the water supply pipeline is necessary for detecting the leak location on the basis of acoustic signals. In this study, a 3D transient leakage acoustic wave propagation equation was derived by combining the principles of fluid dynamics and Lighthill acoustic analogy theory. The propagation of the leakage-induced noise in water supply pipeline was modelled theoretically. We simulated the propagation of a leakage acoustic wave under different conditions for different target scenarios encountered in actual pipeline inspections. Specifically, we analysed the effect of different factors, such as the pipe size and acoustic source characteristics, on acoustic propagation. Finally, the simulated experiments were practically performed using a self-designed simulated water supply pipeline and self-developed spherical water supply pipeline detector to validate the simulation analysis. The results of this study provide a theoretical guidance and basis for the analysis of characteristics of leakage acoustic wave signals and the recognition of leakage conditions in water supply pipelines.

“…Next to this framework, ISO 14040/44 (2006aISO 14040/44 ( , 2006b) also lists data quality requirements that should be addressed in an LCA. However, LCA results are still typically being reported as deterministic [e.g., Bosona and Gebresenbet (2018) and Hajibabaei et al (2018)]. Other studies do include an uncertainty analysis, but completely disregard the distinction between uncertainty and variability [e.g., Bautista et al (2018) and Jiao et al (2019)].…”
