MWH Treatment has joined RSK Group Ltd.

A highly reputable company with a 200-year legacy, MWH Treatment currently operates across the UK water industry, with over 800 professionals co-located across six major frameworks. MWH Treatment provides a strong focus on the safe delivery of sustainable solutions with maximum positive impact on the environment.

The addition of MWH Treatment continues two years of significant strategic investment in the water sector by RSK, with acquisitions including Water Research Council (WRc), Nicholas O'Dwyer and Binnies (formally the UK and Asia water businesses of Black & Veatch). MWH Treatment will move forward retaining its leadership team, all employees, its highly respected brand and its existing cultural values.


RSK will bring real value through its ambition, portfolio of companies and sector links. This will enhance MWH Treatment’s services and enable the company to maintain its position as the number one process contractor in the water industry.

MWH Treatment Managing Director, Paul Bresnan, expressed his delight at the acquisition, said: "I am incredibly excited for MWH Treatment to be taking this fantastic next step. Being part of RSK will enable us to bring a broader and deeper offering to our clients by leveraging the wider group capabilities.

"RSK really values our exceptional people along with the great relationships we have with our clients and joint venture partners."
