Tree roots in sewer line — Dordrecht, South Holland
Tree roots naturally seek moisture and can infiltrate sewer lines through tiny cracks or joints. Once inside, roots expand rapidly, trapping debris and creating blockages that worsen over time. Early signs include slow drains throughout the house and gurgling toilets. If left untreated, roots can collapse the pipe entirely, requiring expensive excavation. A plumber can run a camera inspection to locate root intrusion, clear the line with a mechanical auger or hydro-jetting, and recommend repair options ranging from chemical root treatments to trenchless pipe relining.
Why this is common in Dordrecht
Dordrecht is an island city on the Oude Maas, Beneden Merwede and Wantij rivers, built on soft Holland-polder soil with a high water table — drainage, sump pumps and damp-cellar work are routine, and the centuries-old historic-centre stock often hides lead-era and end-of-life pipework that needs full re-piping during renovation.
