IWS acquires Tetrasolv
Tetrasolv is set to operate as a subsidiary of the IWS group, maintaining its manufacturing headquarters in Anderson, Ind., alongside its strategic service centers in Texas, Florida and Pennsylvania.
Integrated Water Services, a provider of modular water and wastewater treatment solutions, has acquired Tetrasolv Filtration, an industrial filtration systems manufacturer and service provider.
The acquisition integrates Tetrasolv's advanced purification systems with IWS's turnkey wastewater treatment solutions and 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 company 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.
IWS is owned by Sciens Water, an 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, 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 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, Ind., 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 June 22, 2026.
