Technically advanced portal for tracking rain- and wasterwater incidents in sewage pipes.

The challenge

A fiber with measuring points is pulled through the sewage pipe in which
it lies in for a time period and measures the temperature along the cable. This
fiber wiggles in the sewage pipes and is pulled up and down by wells along the way.
Thus, one meter on the cable does not correspond to one meter of sewage pipe. That is why it has been a challenge to find the best solution, which tracks leaks in sewages under ground.

The Solution

In collaboration with EnviDan and a research group at Aarhus University, we developed a web portal for detecting leaks in sewers.

Temperature bitmaps are sent to a web portal where data can be analyzed. A research unit at Aarhus University delivered the algorithm for analyzing temeperature-bitmaps. From the web portal, the technician can compare measured data with a map and identify exactly where a doctor is and under what weather conditions the leak occurs. Afterwards, the real-world leakage can be found and dealt with.

From EnviDTS, integration to several of EnviDan’s systems exist, such as Dandas and GIS along with external systems as for collecting data on rainy weather.
