The International Conference on Sewer Processes and Networks
The International Conference on Sewer Processes and Networks (SPN) is held every 3rd year by the Sewer Systems and Processes Working Group under the IWA specialist group on Urban Drainage (Joint IAHR/IWA). The last of these conferences, the SPN 8, SPN 9 and SPN 10, were held at TU Delft in Rotterdam, The Netherlands, at Aalborg University in Aalborg, Denmark, and at TU Graz in Austria. The next SPN will be held from 19th to 22nd of May 2026, and we are happy to host the 11th edition of the International Conference on Sewer Processes and Networks in Trondheim, Norway at the Norwegian University of Science and Technology (NTNU).
Topics
To underline the virtues of being a specialist conference there are no parallel tracks so as to allow all attendees to participate in discussions.
The main themes for the conference are:
- Sewer system impacts
- In-sewer processes
- Design and operational issues
- Monitoring and associated technologies
- Emerging issues and new technologies related to sewers
These topic areas have been selected to encompass all the scientific and technical areas (physical/chemical and biological processes, operation, monitoring and management) that are important for sewer networks. The topics cover pure scientific topics as well as more technical fields of interest, such as sewer asset management and inspection techniques.
