Infiltration and inflow (I/I) of non-sewer water into the urban sewer system are critical problems in the long-term for sustainable urban water management and water infrastructural asset management, which has serious environmental, social and economic impacts on cities and sewer systems, like increasing the risk of hydraulic overloading of the pipe network, pumping costs, energy consumption and maintenance requirement. By detection and localization of the unwanted water in sewer system and removing this water, sewer systems efficiency and functionality will be improved.

The aim of this project is applying commonly used and advanced methods of localizing and quantifying the level of I/I in sewer systems, and identifying advantages and limitations of each method. A combination of using these techniques can provide sewer operators possibilities to compare different technologies and reducing assumptions and uncertainties in assessing and localizing I/I in the sewer system and support the decision-making in maintenance and rehabilitation plans with more accurate and reliable data about location and magnitude of I/I in the sewer system.
