Short description: In this paper, the authors present a novel approach to directly quantify exfiltration from sewer systems with the help of tracers. The loss of wastewater is computed with a mass balance for the reach under study. An experimental method was developed and tested, and an application study for validation purposes was analysed. It is shown that the use of sodium chloride as a tracer implies certain drawbacks that mainly originate from the varying natural background concentrations. Problems concerning the experimental procedure and the data analysis procedure are identified and discussed. As a proven method for the quantification of exfiltration should have a low measurement error, further development of the tracer method should concentrate on the assessment of the overall measurement uncertainty.
