Toelichting (Engels) A newly developed technique using distributed temperature sensing (DTS) has been developed to find illicit household sewage connections to storm water systems in the Netherlands. DTS allows for the accurate measurement of temperature along a fiber-optic cable, with high spatial (2 m) and temporal (30 s) resolution. The objective of this paper is to introduce the DTS method for the purpose of illicit connection detection in storm water sewers. It aims at examining the possibilities the method offers as well as assessing the quality of the method in terms of reliability, implementation costs and practical feasibility. In the remainder of this paper we will first introduce illicit connections on occurrence, effects on receiving waters and current detection techniques. Next, the concept of using differences in temperature characteristics for the detection of illicit connections is discussed. The technique of using fiber-optic cables for distributed temperature sensing is explained. The DTS-technique has been tested in two municipalities in the Netherlands under different circumstances. The results of these experiments are presented and discussed.
