With the agreement, 800 MWH employees working in six large frameworks will become RSK.
It is the latest move for RSK in the water sector after two years of significant investments with acquisitions such as Water Research Council (WRc), Nicholas O’Dwyer and Binnies (formerly Black & Veatch’s UK and Asian water companies).
MWH Treatment keeps its management team, all employees and its 200 year old brand.
Paul Bresnan, Managing Director of MWH Treatment, said: “I am incredibly excited that MWH Treatment is taking this fantastic next step. As part of RSK, we can offer our customers a broader and deeper range by using the broader capabilities of the group. “
“RSK values our exceptional people and the great relationships we have with our customers and joint venture partners,” he added.
Alan Ryder, founder and CEO of RSK, said: “The water sector is of enormous importance for RSK and its strategy, so I am very pleased to welcome MWH Treatment to the group. The company’s reputation across the UK is impeccable and I see endless opportunities for collaboration and knowledge sharing within the group.
“Paul and his team have values that are very similar to those of the entire RSK Group – something that, in my opinion, is so important for bringing companies together.”
