The TDH Company

What The TDH Company does

The TDH Company is a manufacturers' representative firm specializing in engineered water and wastewater treatment equipment for the municipal public works market. Founded in 2000 and headquartered in Marietta, Georgia, the company serves public agencies, outside consulting engineers, and in-house utility engineering teams across Georgia, Alabama, Tennessee, and the Florida Panhandle. Its portfolio covers the entire treatment train — headworks and pretreatment, mixing and aeration, biological treatment, clarification and filtration, chemical feed and disinfection, solids handling and biogas, odor control, valves and gates, instrumentation, blowers, and emerging PFAS capture and destruction technologies — sourced from more than 50 manufacturer partners including Xylem (Sanitaire, Flygt, Wedeco, EVOQUA), Parkson, ProMinent, Aerzen, Duperon, WesTech, Komline, World Water Works, and GEA-Westfalia.

The company's commercial offering combines capital equipment specification support (assisting consulting engineers with selection, written specifications, and present value analyses), commission-based equipment sales through territory-based field reps, and post-sale aftermarket support including parts, calibration, preventative maintenance, and repairs. Its sales team includes multiple Registered Professional Engineers and Class 1 licensed wastewater operators, enabling specification-stage influence and credibility with technical municipal buyers. Notable deployments include the 4.88 MGD Slab Creek WRF phosphorus reduction project for Boaz Water & Sewer Board in Alabama, integrating Sanitaire Casperon biological nutrient removal, Parkson screening, Xylem/Flygt mixers, and Komline aeration.

The TDH Company operates as a wholly-owned subsidiary of Unified Flow Technologies (UFT), a strategic operating platform that has built a Water and Wastewater Platform through acquisitions of complementary rep firms. Following the sale of the predecessor partnership to UFT, the company is led by President Clint R. Curl with Vice Presidents L. Holman Waters and Rick Calmes. The firm runs lean — listed at 1-10 employees — and concentrates on territory-protected representation rather than direct manufacturing, making manufacturer relationship depth, engineering credibility, and consulting engineer specification influence its primary competitive levers.
