Trihydro Continues to Rank Among the Top U.S. Environmental Firms
Trihydro is pleased to announce ranking No. 119 on the 2017 Top 200 Environmental Firms list by Engineering News-Record (ENR). This is the twelfth consecutive year that Trihydro has made the list, debuting at No. 171 on the magazine’s annual ranking in 2006. 

ENR states that despite regulatory and market uncertainties, “the Top 200 Environmental Firms held their own in 2016” as “list participants in their overall revenue last year managed a 2% hike, to $54.47 billion— a total not seen in five years.”

The ENR report also anticipates progress for emerging economies including water availability and water quality services, which supports Trihydro’s expansion of water-based resources with this year’s acquisition of River City Engineering, a Texas-based consulting firm that specializes in water and wastewater services. 

In addition to its enhanced water services, Trihydro’s continued growth of personnel and office locations has increased the company’s ability to provide expertise and quality solutions to its clients’ air quality, engineering and surveying, health and safety, and other environmental needs.
