Urban Sewer Systems: Monitoring, Modeling and Management

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.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
