Method for leak detection in a pipeline system, more particularly in a water supply and sewer system. The purpose of the invention is to efficiently and with great accuracy determine the scope and location of damages in the line system. For this purpose leakage indicating means are employed that comprise tracers, which are supplied to the water running through the pipes, each pipe being supplied a special tracer. Samples are taken at certain points downstream in the system. These samples are analysed and the concentration of tracers is determined. Using the concentration figures, the inflow of tracers from adjacent pipes can be established, in respective pipes. Thus, an estimation of the leakage from and to each pipe can be made. |
