Drainage channel cleaning

Drainage channel cleaning is the removal of leaves, silt and debris from linear surface channels and the connection pipes that feed the foul or surface water system. Channels are widely used across patios, driveways, threshold strips at sliding doors and commercial yards in London office and retail developments. Cleaning involves lifting the gratings, manual removal of larger debris, vacuum recovery of silt and jetting of the connection pipework. Engineers should also check for cracked channels, lifted joints and broken gratings, as these allow ingress of more silt and create trip hazards. Routine cleaning every six to twelve months addresses common causes of overflow during heavy rainfall and is a sensible part of routine property maintenance.
