Who We Are
The Water Jetting Association (WJA) is a trade association representing contractors, manufacturers, hirers and other organisations that have a professional and commercial interest in all aspects of high-pressure water jetting.
WJA support the highest possible safety and technical standards for all forms of water jetting, including ultra-high-pressure water jetting, high pressure water jetting, pressure washing, and drain and sewer cleaning.
WJA are also committed to furthering our members’ interests – in terms of commercial opportunities, brand association, technical advice and high-pressure water jetting training.
Water Jetting Codes of Practice
We have developed two detailed Codes of Practice for water jetting – the ‘Blue Code’ for high-pressure and ultra-high-pressure water jetting, and the ‘Red Code’ for use of water jetting in drains and sewers.
Both Codes of Practice are ISBN-designated. They have been developed, and are regularly updated, with the assistance of industry stakeholders and support from the UK’s Health and Safety Executive.
The Codes of Practice are recognised as setting important industry standards for high-pressure water jetting in the UK and internationally. They also represent a valuable tool for members seeking to deliver safe, productive and reputable water jetting services.
Education and Training
As the UK’s largest provider of water jetting training, we are dedicated to development of high-pressure water jetting skills and promoting wider understanding of its potentialities and applications.
WJA courses are accredited by the City & Guilds of the London Institute and are recognised as setting the industry standard for high-pressure water jetting training. Courses are delivered in the UK and internationally through WJA-registered training providers and by WJA-approved trainers.
Promotion of Members Interests
The WJA maintains a Directory of Members which can be accessed via our public website and is made available to relevant organisations. The directory has become a valuable resource for prospective customers who need the services of high-quality water jetting service providers.
Our purposes and aims are laid out in the WJA constitution. The WJA is led by a President, Vice President and a Ruling Council, all elected by association members in an Annual General Meeting.
All members sign their acceptance for, and are bound by, the WJA Professional Charter.
Day-to-day affairs are managed by proficient, professionally-qualified staff who have substantial experience in all aspects of the water jetting industry.
