building=sports_centre ? Is something changed here ? If not building=office.

osm.org/way/1233514964 is realy suspicious.

On previous research i made the culvert going to a collector in Berboets osm.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 ...)

Proably Wetland here more survey needed.

The spring is maybe a little more to the east ; if not there is a wetland in the east zone visible on Digitaal Vlaanderen DHV II, Skyview factor 0,25 m

More research and survey needed (also to find why there's only one spring on a park named in plural).

The actual construction of the bridge for bicycle is not only a cycleway but also a man_made=wildlife_crossing named "De Priorij" : https://www.werkenaandering.be/fr/travailler-sur/infrastructure-cyclable/ecorecreaduc-gravendreef
