Attended an emergency call following a full main sewer blockage backing up through multiple manholes. To keep costs down and speed up the works, overpumping was set up instead of tankering until the surcharge was released and the blockage could be safely worked on. A large lump of tarmac was removed from the system, relieving the full run. All manholes were cleaned using a tanker and jetting van, followed by a full CCTV survey confirming the main was clear with no further defects. A full diary of works — including photographic and video evidence — was issued to the developer to review the cause and recover costs where required. All works completed within 1 day.
