Special Issue Information

Dear Colleagues,

Sewer systems serve as critical urban infrastructures, responsible for safely conveying sewage from households and other sources to treatment facilities, thereby protecting public health. However, they face a myriad of global challenges including insufficient capacity leading to frequent overflows and pollution, blockages, corrosion, and the generation of foul odors due to hydrogen sulfide production.

Current management strategies adopted by water utilities tend to be reactive due to the limited understanding of sewers and predictive capabilities of available tools. While various technologies exist to address these challenges, further optimization and comprehension are necessary. Continuous monitoring and modeling of sewer systems are indispensable for assessing conditions and performance, enabling proactive management. Despite the emergence of new technologies, their effectiveness and longevity in harsh sewer environments remain uncertain. Consequently, numerous unresolved research questions persist regarding the methods, tools, and technologies for effective sewer management. Addressing these challenges is crucial to ensure the resilience and sustainability of urban sewer systems, enhancing their capacity to meet the evolving needs of expanding urban populations.

This Special Issue of Water welcomes papers aiming to address these research gaps and contribute to the development of knowledge and technology for cost-effective sewer management. This includes papers focusing on the following topics:

  • Emerging technologies in sewer monitoring;
  • Hydraulic modeling of sewer systems;
  • Sewer process modeling;
  • Real-time control and process optimization;
  • Application of modeling tools;
  • Sewer overflows;
  • Sewer operation;
  • Sewer-asset management.

With urban expansion, traditional drainage systems in densely populated cities face significant challenges, leading to frequent flooding and pollution issues. Deep tunnel drainage systems emerge as an innovative approach, offering underground storage for excess precipitation and alleviating urban inundation. This research investigates the deployment of a deep tunnel system in Guangzhou’s densely populated urban core. By integrating with existing networks, this system aims to curtail over-flow contamination and boost sewage-handling capacity. Successful implementation hinges on the thorough evaluation and synchronization with broader urban development objectives. In Guangzhou, where traditional methods fall short, deep tunnels present a viable option. This study explores techniques for identifying drainage deficiencies, devising enhancements, and refining citywide strategies. Economic analysis indicates that deep tunnels are more cost-effective than conventional drainage upgrades, offering long-term benefits for land conservation and drainage efficiency. Following implementation, these systems markedly enhance sewage management, diminish overflow incidents, and improve pollution mitigation. Although initial investments are substantial, the enduring advantages in land preservation and drainage efficiency are significant. Thus, deep tunnel systems emerge as a practical flood control solution for high-density urban areas like Guangzhou, fostering sustainable metropolitan growth. Full article
