Prepare and use high pressure jetting equipment for sewerage or drainage maintenance

This standard is about preparing and using sewer and drain high pressure water jetting equipment on sewerage or drainage assets to remove blockages, deposits or materials. Sewerage and drainage assets can be in public networks or privately owned. Jetting equipment can be automated, semiautomated or remote controlled.
It includes selecting components, assembling jetting systems, filling machine water tanks, operating jetting equipment, disposing of waste and dismantling and storing equipment. High pressure water jetting is high risk work and appropriate training should be completed before it is undertaken
This standard is for operatives who use sewer and drain high pressure water jetting equipment on public or private sewerage or drainage assets including those working in sewerage pumping stations.

9. carry out all work and use appropriate PPE in line with organisational health and safety procedures
10. direct and guide water jetting nozzles through system hydraulic, motorised or pneumatic operated reels to remove blockages, deposits or materials as specified in work instructions and in line with organisational procedures and safe systems of work
11. monitor sewers and drains during jetting activity, evaluate any changes and take appropriate action to deal with it in line with organisational procedures and safe systems of work
12. use CCTV equipment when required to check that blockages, deposits or materials have been removed to the expected standard
13. communicate with relevant people in line with organisational requirements, when required to ensure the smooth completion of the work
14. complete jetting work in line with organisational requirements, communicating requirements for any additional visits or redeployment with responsible person
15. dispose of waste in line with organisational procedures and environmental standards and regulations
16. resolve any user serviceable faults or damage to jetting equipment that are within your responsibility, reporting any that you cannot resolve to appropriate people
17. decontaminate and store jetting equipment in line with organisational procedures for safe transport.
18. make working area safe in line with organisational procedures and safe systems of work when work is completed
