MGC Contractors, Inc. is a Phoenix-based construction firm focused on water and wastewater projects. An Arizona corporation operating since 1982, it traces its origins to MGC Contracting, Ltd., which began in 1974. The company offers multiple project delivery methods—from Job Order Contracting to Construction Manager at Risk, Design-Bid-Build, and Design-Build—and works across Arizona, Texas, Utah, and New Mexico.

In May 2026, MGC signed a new client in New Braunfels, Texas, to undertake a wastewater treatment plant rehabilitation project for New Braunfels Utilities. That same month, Carollo Engineers, Inc. partnered with MGC on a progressive design-build effort organized into multiple packages to align funding, manage risk, and address pandemic-related challenges.
