About Us

Heritage Hydro Governor Service, Inc. is a certified Woman-Owned Small Business with more than thirty years of experience maintaining and repairing mechanical and hydraulic industrial machinery. More than one-half of that time has been focused on working hands-on with vintage mechanical and early digital hydro turbine governors and associated equipment. Utilizing our extensive Woodward Governor Company factory and on-the-job training, first-hand experience and knowledge, we specialize in legacy hydro controls and auxiliaries manufactured by Woodward. We can also support other manufacturer’s legacy controls to keep your hydro plant up and running. We are dedicated and available to perform work at Hydro Sites across the United States.
