Key Personnel

Interflow employs over 500 personnel, many of whom have worked for the Company for in excess of 20 years. Some 50 are degree qualified civil, mechanical or environmental engineers.

The specialised nature of Interflow’s work means that the company invests heavily in in-house training and on-the-job learning not offered elsewhere in this field.

The Company’s background has meant that it has retained highly experienced Engineers and Project Managers who have been valuable in developing safe and effective work practices in the highly specialised field of “trenchless” pipeline rehabilitation. Their experience is passed to employees involved on our projects.
