The river Wurm is by the North East side of Dremmen where the industrial area is situated by Hückelhoven.
In the Middle Ages, a Mühlengraben (channel for the operation of water mills) was created, at Randerath where the river Wurm branched off.
In the city of Heinsberg, it was destroyed during the Second World War (Jan 1945: Operation Blackcock) and wasn't restored after, the channel was instead used to irrigate agricultural land.
Built in 1890, the railway line Heinsberg-Lindern ("Wurm Switchback") also runs past Dremmen.
Pedestrian areas were decoratively paved and separated by green spaces and small walls on the roadway.
