Trondheim, Norway

The International Conference on Sewer Processes and Networks (SPN) is held every 3 years by the Sewer Systems and Processes Working Group under the IWA specialist group on Urban Drainage. To underline the virtues of being a specialist conference there are no parallel tracks to allow all attendees to participate in discussions.

The 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.
