The incorrect use of high pressure jetting equipment to remove blockages and sediments from drains and sewers can lead to damage of the pipeline materials and joints. This Code of Practice provides the only independent and authoritative guidance on good working practice when using high pressure water jetting equipment for unblocking and cleaning. It covers jetting in all types of non-man-entry sewers and drains (including highway drains) whether private, public or due for adoption.

This second edition of the Code of Practice has been updated in light of recent regulations that impact upon sewer jetting. The method of working section has been redrafted to clarify the maximum pressure limits to be used and to provide clearer guidance with regard to working from different directions to clear blockages. Also, for the first time, this edition includes an outline of the training requirements for all operatives.
