John Jones

J R Jones Consultancy

I have worked within the water jetting industry for over 40 Years and been a contractor with Leigh Interests, Veolia and Campus Veolia and during this time was a WJA Council member. In 2016 I became a WJA Training Provider and Instructor and have been the WJA Safety & Training Committee Chairman and WJA President of the Association. I am really looking forward to working alongside John as the Membership Board member.

John Rhodes

I have been involved with high pressure water jetting since 2007, when I began working for an environmental services company, starting as a junior jetvac operator working on large contracts for several water companies. I am an approved Training Provider/Instructor and have delivered courses to delegates from a wide range of industries and backgrounds. I began taking part in the WJA Safety & Training committee in 2018, and I like to think my input has been useful since. I have a lot of ideas, energy and enthusiasm to contribute to the Association as it continues to evolve.
