COLORADO SPRINGS, CO — Wind River Environmental, the leading provider of non-hazardous liquid waste services in the Eastern United States, has acquired GDM Environmental, a Colorado-based specialist in grease and septic services. The deal, announced August 28, 2026, marks Wind River's first move into the western United States — opening an entirely new region for the company's growing portfolio of septic, grease, wastewater, vacuum truck, and hydro excavation services.
GDM Environmental has built a strong reputation across Colorado for reliable and efficient grease trap and septic services, serving both residential and commercial customers throughout its service footprint. Its established customer relationships and operational infrastructure give Wind River an immediate platform from which to grow its western presence across both commercial and residential lines of business.
For Wind River, the acquisition is the latest in an aggressive expansion strategy that has now surpassed 100 completed acquisitions. The company, which operates in 16 states with a team of more than 1,000 employees, offers a comprehensive suite of non-hazardous liquid waste solutions — including septic pumping, grease trap maintenance, lift station services, catch basin cleaning, sludge removal, vacuum truck services, and hydro excavation — to residential, commercial, municipal, and industrial customers.
"Integrating GDM Environmental into our operations highlights our commitment to expanding our footprint and delivering exceptional waste management solutions," said Dave Parry, CEO of Wind River Environmental. "We are excited to welcome GDM's dedicated team and loyal customers into the Wind River community."
The GDM acquisition follows Wind River's June 2026 acquisition of HydroTech Environmental and its March 2026 acquisition of J&M Transfer, Inc., reflecting a sustained pace of growth as the company extends its reach beyond its Eastern U.S. base.
