| Short description: |
The structural state of sewer pipes is a crucial problem in urban areas because infiltrations and exfiltrations can occur and consequently contaminate the surface and deep water bodies, respectively. In this paper the application of a new method to quantify the sewer leakages (called exfiltrations) with tracers during dry weather is discussed. This method, called QUEST-C (Quantification of Exfiltration from Sewers with the help of Tracers-Continuous Dosing), developed by EAWAG (CH) within the European project APUSS, allows to estimate the exfiltrations by a mass balance of chemical tracers dosed continuously in a wastewater stream of operating sewers.

In the paper, we sum up our experience from a number of field experiments in order to discuss the application of the method in the field, critically: (i) planning of the experiments; (ii) the reliability of the obtained results; (iii) the overall applicability of the method in an urban area. Finally, some findings with regard to the practical application and recommendations are presented for the future development of the method.
