Integrated Water Services, Inc. (IWS), a U.S.-based provider of modular wastewater treatment and water reuse systems, has announced the acquisition of Tetrasolv Filtration, a company specialising in filtration, separation technologies, mobile media services and rental solutions.
The move is intended to broaden its capabilities in advanced water treatment by combining Tetrasolv’s purification technologies with IWS’s turnkey wastewater treatment and aftermarket service offering. The transaction follows IWS’s recent acquisition of Complete Filtration Resources, which expanded the group’s process filtration portfolio in the dairy, food and beverage sectors.
These additions strengthen the companies’ position in the industrial and municipal mid-market, with a combined offering that includes membrane bioreactors (MBR), aeration systems and advanced media filtration technologies. IWS is owned by Sciens Water, an investor focused on the U.S. and international 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.”
Tom Rooney, chairman of IWS, added: “We are committed to supporting IWS's strategy and rapid growth. 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.”
Tetrasolv will continue operating as an IWS subsidiary, retaining its manufacturing headquarters in Anderson, Indiana, as well as service centres in Texas, Florida and Pennsylvania. The combined organisation aims to support water reuse and environmental remediation projects across the United States.
