In the UK, water jetting is widely used in drainage, sewer maintenance, and industrial cleaning. But with high-pressure equipment comes high risk. That’s why Water Jetting Association (WJA) approved training is not just recommended—it’s essential.
If you or your team are working in drain and sewer environments, the WJA Safety Awareness and Drain and Sewer Cleaning training courses provide the knowledge and certification needed to work safely, legally, and effectively.
What Is WJA Safety Awareness Training?
The WJA Safety Awareness course is the foundational training course approved by the Water Jetting Association. It’s designed to help operatives understand the health and safety principles of high-pressure water jetting—equipment that can cut through concrete, and, if used incorrectly, cause life-threatening injuries.
Topics covered include:
- Introduction to water jetting and pressure systems
- Health and safety legislation (PUWER, COSHH, PPE regs)
- Safe setup and operation of jetting units
- Risk assessment and hazard identification
- Environmental considerations
- Emergency procedures
Upon successful completion, delegates receive a WJA certificate and WJA registration card valid for 3 years.
What Is the WJA Drain and Sewer Cleaning Course?
For those working specifically in the drainage and utilities sector, the WJA Drain and Sewer Cleaning course is a vital follow-up. It builds on the safety awareness module with practical and technical knowledge specific to drain and sewer maintenance using jetting equipment.
You’ll learn how to:
- Use high-pressure jetting for unblocking drains
- Carry out safe confined space and roadside operations
- Identify drainage system types and access points
- Understand backflow, suction hazards, and exposure risks
- Implement control measures for working in contaminated or sensitive areas
The course includes both theory and hands-on training, and successful delegates receive an additional Drain & Sewer Cleaning module endorsement on their WJA card.
Who Should Attend?
These courses are ideal for:
- Drainage engineers
- Jetting operatives
- Utilities and civil engineering workers
- Local authority and highways maintenance staff
- Contractors working with confined spaces or surface water systems
Whether you’re a new starter or need to renew your WJA registration, these short courses are the industry standard.
