We are very pleased to announce the return of MWH Constructors as WCDA members! Represented by Ray Montoya, senior vice president, Quentin Williams, senior vice president of business development, and John Lisman, senior manager of pursuits and creative content, the MWH team is poised to once again be a great contributor to WCDA’s mission to transform the water sector through education, advocacy, and research.

As a leading national water- and wastewater-treatment-focused general contractor with experience in both municipal and industrial applications, MWH is committed to providing exceptional value through a comprehensive suite of services from preconstruction and digital delivery through hands-on construction expertise and commissioning and startup. While they are experienced in traditional design-bid-build projects, our true expertise shines in collaborative delivery models such as construction management at-risk (CMAR) and design-build (DB).
