Bosmans Rioolservice Assen
Your drain engineer in Assen
Assen is the capital of Drenthe and has a green character, with the Asserbos woods close to the centre and spacious districts such as Lariks, Pittelo and Marsdijk. In the west, Kloosterveen has grown over recent decades into a large new-build district. Our drain engineers work in every district of Assen and in the villages around it.
A sink that will not empty in Peelo, a leak in a flat in the centre or a sewer backing up in Noorderpark: you call and we come, day and night, with an arrival time you hear in advance.

Local knowledge
What we often come across in Assen
Green districts
Assen has many trees along streets and in gardens. Roots seek out the drain and grow in through the joints. We cut them out and advise on relining if the pipe calls for it.
Kloosterveen
Kloosterveen has modern plastic pipes. A blockage caused by grease or wet wipes is usually found quickly there and cleared in one visit.
Homes from the sixties and seventies
In Lariks, Pittelo and Peelo the pipes have been in service for a long time. A CCTV survey shows whether cleaning is enough or whether a new inner wall is the better choice.
Busy days and hospitality
On busy event days and in the restaurants and cafés in the centre, drains are under heavy use. We schedule preventive jetting so everything keeps draining freely just when it matters.

Drain services Assen: what you can call us for
Toilet unblocking in Assen
Our engineer quickly gets a blocked toilet in Kloosterveen, Marsdijk or Assen-Oost working again. With a drain snake or high pressure we remove the blockage right into the pipe and then flush through thoroughly. If we notice the toilet blocks more often, we look with the camera to find the real cause.

In Assen's wooded districts, tree roots are a well-known cause of a blocked sewer. We jet the pipe at high pressure and cut out roots right up to the main sewer. We then check that everything drains freely again, so in Lariks, Pittelo or Baggelhuizen you can shower and flush with peace of mind.
