Design and consulting company Stantec Inc. purchased water and infrastructure design firm MWH Global earlier this month in a massive merger.

MWH Global had 64 employees in Bellevue and they will join Stantec’s Lynnwood and Bellevue teams for 250 employees in the area, 90 of which are water project experts.

The MWH Global team located in Bellevue had tackled the Green River filtration facility project for the city of Tacoma. The Broomfield, Colorado-based company employed more than 6,800 worldwide and focused on water and natural resources for built infrastructure and the environment.

MWH Global shareholders overwhelmingly approved the merger in March.

The company was known for serving as lead designer on the Panama Canal third set of locks project in Panama, a Thames river project in London and construction manager for Austin, Texas’ local water treatment facilities.

Stantec will now employ more than 22,000 around the world in more than 400 offices.
