Unrivaled Heritage.

Established in 1820, MWH, now part of Stantec, is now one of the largest environmental services firms in the world. Trust and integrity underpin everything we do. We have pioneered many water and energy based technologies, including the development of the first large-scale process for purifying municipal wastewater.


Our work is based on a dynamic vision and a desire to stay at the forefront of new developments. We encourage our staff to think creatively whilst understanding that we do not always need to “reinvent the wheel”. We harness our local strengths, and by linking it to a worldwide network, we provide our clients with access to global knowledge.

Social Responsibility.

We promote sustainable development in our society, environment and the economy. We conduct and support educational outreach programmes designed to encourage sustainable practices. We have an embedded Corporate Responsibility Policy and our own Climate Change Commitment to further reduce our company’s carbon emissions.

'Best Place to Work'.

MWH was awarded ‘Best Place to Work’ at the 2016 NCE Companies of the Year. Judges thought we excelled in our ability to demonstrate clear well communicated corporate values and exceptional leadership demonstrating a commitment to wellbeing initiatives across a number of areas, including mental health.
