About this Research Topic
The majority of underground utility assets are comprised of water transmission, distribution, and collection pipelines. Because these pipes are typically buried underground and aging over time, the asset management tasks, including inventory data collection, condition assessment and decision making are complex processes that are challenging to enhance sustainability without advanced research and innovation in utility asset technology. Recent studies have revealed an overall increasing rate of decay of underground infrastructure, which result in decreasing a utility’s liability of infrastructures. The significant deterioration of urban water infrastructure is accompanied by emerging uncertainty in the performance of these networks. This uncertainty signifies the importance of developing intelligent decision tools to increase the operational resilience of these assets by targeting the right ones for further intervention. Enhanced mitigation strategies involve the implementation of optimized and cost-efficient decision support tools, as well as minimally disruptive condition assessment, repair and renewal methods.
An efficient and successful development of underground utility asset management promotes trenchless technology; an important group of pipe repair and installation methods that minimize disruption during construction. Trenchless technologies have developed rapidly and continue to have regular innovations in the industry. From this constant innovation, breakthrough achievements emerge in numerous areas annually.
The goal of this Research Topic is to highlight:
• Novel research trends in the smart urban water infrastructure management field, including, but not limited to, decision support tools, methods and strategies to optimally allocate financial resources towards high-risk assets management measures;
• Recent advances in proactive mitigation strategies focused on the implementation of trenchless technology as a cost-efficient pipe repair and renewal solution.
Areas to be covered in this Research Topic may include, but are not limited to:
• Re-engineering traditional urban water infrastructure management practices with smart management strategies
• Applying innovation and creativity to tackle uncertainty due to various unforeseen and undesired events, e.g. droughts, flooding, local economic hardships, seismic activity, and global pandemic
• Development of actionable solutions by integrating big data, analytical tools, advanced GIS models, statistical models and artificial intelligence
• Development of innovative pressure and non-pressure pipe repair materials and test methods to decrease construction costs and allow utilities to efficiently allocate their tightening budgets to maximize their capital improvement projects. Some examples of such research include reinforced spray-on coting material, innovative curing methods for spray-on cementitious coatings, new surface wave techniques for pipe assessment, and innovative methods for pipe removal)
Papers submitted to this collection should highlight both the practical application of these innovations, but also the fundamental advancements and scientific theory behind them. Authors are encouraged to prepare and submit their original research works focusing on, but not limited to:
