IWS Acquires Tetrasolv, Expanding Advanced Water Treatment, Rentals, and Field Service Capabilities
AUSTIN, Texas, June 23, 2026 /PRNewswire/ -- Integrated Water Services, Inc. (IWS), a pioneer in modular wastewater treatment and reuse systems, today announced the group has acquired Tetrasolv Filtration, an industry leader in specialized filtration, separation, and mobile media services and rentals.
The acquisition accelerates IWS's vision to redefine the water lifecycle by integrating Tetrasolv's advanced purification systems with IWS's turnkey wastewater treatment solutions and compelling aftermarket services. This milestone follows IWS's recent acquisition of Complete Filtration Resources, which expanded the group's portfolio of advanced process filtration capabilities into the dairy, food, and beverage markets. Together, these strategic acquisitions establish a unique technology powerhouse for industrial and municipal mid-market clients, delivering highly sophisticated treatment technologies—including MBR, specialized aeration, and advanced media filtration—at the lowest Total Cost of Ownership (TCO).
IWS is owned by Sciens Water, a prominent investor in the U.S. and global water sectors.
"Welcoming Tetrasolv into the IWS family advances our mission to deliver modular, scalable, process and wastewater solutions with unmatched economic value," said Cody Phipps, CEO of IWS. "As regulatory pressures mount and environmental demands evolve, mid-market clients need sophisticated, reliable technologies with sustaining aftermarket services. By combining Tetrasolv's ASME-certified manufacturing and advanced media capabilities with our core technologies, we are uniquely positioned to transform how water is managed and reused. We are delivering complete, multi-decade infrastructure from day one and protecting both our customers' bottom lines and the environment."
"We are committed to supporting IWS's strategy and rapid growth," said Tom Rooney, the chairman of IWS. "The addition of Tetrasolv adds important new media filtration capabilities and significantly adds to the company's recurring revenue services. We are creating a powerful, and diversified solutions provider to the underserved mid-market segment."
The merger addresses a period of exceptional growth for Tetrasolv, driven by surging market demand across its core purification and remediation sectors including PFAS remediation. Joining IWS provides Tetrasolv with the corporate infrastructure, capital, and expanded engineering depth to scale alongside its customer base and execute larger, turnkey infrastructure programs.
"With the increasing demands and opportunities in the water and wastewater market, we found an ideal strategic partner in IWS," said Doug Dallmer, President of Tetrasolv. "Our customers will continue to rely on our proven Tetrasolv team for rentals, media services, field support, and engineered treatment systems, now backed by greater design-build, engineering, and nationwide service capabilities."
Tetrasolv will operate as a subsidiary of the IWS group, maintaining its manufacturing headquarters in Anderson, Indiana alongside its strategic service centers in Texas, Florida, and Pennsylvania. The unified group will leverage its combined footprint to accelerate sustainable water reclamation and environmental remediation deployments nationwide.
The transaction closed on June 22, 2026.
