https://www.openstreetmap.org/way/1233514964 is realy suspicious. 

On previous research i made the culvert going to a collector in Berboets https://www.openstreetmap.org/note/4014153 but Vivaqua  should disconect it and make a new culvert but not found a lot info about it. (more research needed for this part).

No official data available for the nord part , so maybe it's simply still go to the collector in Bervoet or theres is a new culvert going to the nord but in any case the relief here don't allow the stream going  up to the east ... 

(i suspect  user draw v1 in order to connect on patinage on guessing completly how ...)
