Why Professional Manhole Unblocking is Critical for Lewisham Sites
When an external manhole overflows in Lewisham—whether on a private driveway in the local area or a commercial loading bay in the town center—it represents a total failure of the drainage network. Unlike internal clogs, a blocked manhole usually indicates a deep-seated obstruction in the 100mm or 150mm main lines. Lewisham’s historic brick-built chambers and modern plastic interceptors both face risks from root ingress, silt accumulation, and “fatbergs.” We provide the technical authority to resolve these high-volume failures. Using truck-mounted jetting units, we clear the entire sewer reach, not just the chamber, ensuring the Lewisham infrastructure is restored to its original hydraulic design.
