Our company is the product of three key lineages of engineering firms with long and successful histories.
James M. Montgomery Consulting Engineers (JMM) was formed in 1945 in southern California and recognized for its excellence and specialization in water and wastewater engineering. In the early 1990s, JMM merged with an English firm, Watson Hawksley, Ltd. of High Wycombe, England, which originated in London in the 1850s. This created a company of global scope known as Montgomery Watson.
In 2001, Montgomery Watson merged with Harza Engineering, a Chicago-based energy, water and infrastructure company. The merger brought together two companies with long histories of excellence; similar corporate cultures that honored individual expertise and encouraged teamwork, innovation and initiative; and a common view of the industry’s future. The name was changed to Montgomery Watson Harza and ultimately shortened to MWH.
Today, we continue to be dedicated to innovation and committed to mastering and applying emerging technologies to create client-focused results. We have engaged in the
engineering,
construction, financing and
management of some of the world’s largest and most technically significant wet infrastructure
projects in the world.
