Assessing Exfiltration from a Sewer by Slug Dosing of a Chemical Tracer (NaCl)
7. Conclusions Preliminary results were presented for estimating exfiltration from an urban sewer system by a novel method QUEST, which was developed by EAWAG in the European APUSS project. The application of this method to a structurally sound sewer in Rome proved that the method allows the assessment of exfiltration in an expedient and economic way. These results have provided reliable exfiltration rates on the basis of a sewer structural state. However, the QUEST method can not replace the use of common conventional techniques (e.g., CCTV) for finding exact locations of pipe defects. The paper highlighted the importance of preliminary testing (peak shape study, conductivity and flow rate measurements) and sewer system characterisation, in order to reduce the uncertainty in the results obtained from the proposed models.
