Methods for localization and volume estimation of the infiltration and inflow : Comparative study

• Infiltration and inflow (I/I) into wastewater sewers have numerous negative effects on the whole wastewater system. A number of methods have been developed to estimate performance of sewer system with regards to I/I. This abstract presents and compares selected results of Distributed Temperature Sensing (DTS), Closed-circuit television (CCTV) and ammonium sampling for identifying I/I in wastewater sewers during the snowmelt period, under dry and wet weather conditions. The results showed that different methods produce results that vary in precision, accuracy, time and spatial resolution.
