MWH Global: A Legacy of Water and Natural Resource Engineering

MWH Global Inc. was a preeminent global firm specializing in water and natural resources. By integrating technical engineering, construction services, and strategic consulting, the company provided comprehensive planning, design, and construction management for critical infrastructure projects across the globe. Headquartered in Broomfield, Colorado, MWH Global operated in 35 countries, employing a diverse workforce of 7,000 professionals—including engineers, geologists, architects, and regulatory experts—as of May 2015.

The firm's influence was significant enough to be ranked as the 15th-largest employee-owned company in the United States. In 2016, MWH Global was acquired by Stantec Consulting Inc., though its legacy continues through MWH Constructors, the specialized water and wastewater construction branch of the original organization.

The Evolution of MWH Global

MWH Global was not founded as a single entity but was the result of the unification of three major engineering powerhouses: James M. Montgomery Consulting Engineers (JMM), Watson Hawksley, Ltd., and Harza Engineering Company.

The Foundation: JMM and Watson Hawksley

The journey began with James M. Montgomery, who founded JMM in Pasadena, California, in 1945. Montgomery's expertise was established early through his work on the F. E. Weymouth Memorial Water Softening and Filtration Plant in La Verne, California—a facility designed to handle 100 million gallons per day for the Metropolitan Water District of Southern California.

In 1990, JMM merged with the United Kingdom-based Watson Hawksley, Ltd. This merger combined JMM's specialized water and wastewater engineering capabilities with Watson Hawksley's extensive international operational reach, creating the firm known as Montgomery Watson.

Expansion into Montgomery Watson Harza

The firm expanded further in 2001 by merging with the Harza Engineering Company of Chicago, Illinois. Harza brought renowned expertise in the energy and environmental sectors, particularly in hydroelectric power development. One of their most notable achievements was the El Cajón Dam (officially the Central Hidroeléctrica Francisco Morazán) in Honduras.

Following this merger, the company operated as Montgomery Watson Harza before shortening its name to MWH in 2003.

Final Growth and Integration

In 2010, MWH acquired Biwater Services Ltd., a firm specializing in water construction and engineering. This acquisition included Ames Crosta Babcock, which allowed MWH to trace its historical origins back to 1820 in Heywood, Lancashire, United Kingdom.
