WesTech Engineering is an operating brand under the strategic arm of Swire Water with headquarters in Salt Lake City, Utah (USA).

Founded in 1973, we have over 500 employees who deeply value our customer's trust in us as a water treatment solutions supplier. We are committed to providing superior service safely and sustainably.

With the release of the Clean Water Act in 1972 and the increased focus on solving water pollution problems in the United States, a small group of engineers in California gathered to develop solutions to improve water quality.

Since then, WesTech has become a global leader in water and wastewater treatment solutions and liquid/solids separation.

Today, we are proud to design, build, maintain, and operate equipment and systems that provide clean water and enable communities to thrive.
