Terms have been agreed for Celtic Water Care Solutions Limited (Celtic Water Care), a Cork-based wastewater and effluent treatment chemicals specialist serving private-sector customers across Ireland, to be acquired by Irish-owned chemical solutions provider Chemical Solutions Group (CSG).
The transaction will bring CWC into the group as a wholly owned subsidiary and supports CSG’s long-term growth strategy, with the €65M business targeting revenues of €150M by 2030, complementing its recent expansion into the UK and ongoing multi-million euro investment at its sites in Shannon and Foynes.
Founded in 2000 and employing 14 people, Celtic Water Care Solutions Limited has built a strong reputation in the Irish industrial wastewater market by combining specialist treatment chemicals with equipment, on-site expertise and a highly consultative, problem-solving approach. They currently support more than 200 customers across Ireland, including food and beverage manufacturers, dairy processors, design-build-operate contractors and pharmaceutical sites.
The transaction, which is subject to merger control clearance by the Competition & Consumer Protection Commissions (CCPC), is expected to complete during Q1 2026.
CSG is the parent company and comprises of Chemifloc, GI Chemicals Ireland, GI Chemical Solutions UK, and Chemilab and currently employs 100 people, bringing more than 40 years of specialist chemistry expertise across potable water, wastewater, environmental and hygiene applications, operating across Ireland and the UK.
This acquisition will enable CSG and Celtic Water Care Solutions to offer customers a more integrated, end-to-end solution, technical support and on-the-ground service, with a shared emphasis on reliability, safety and long-term partnerships.
Under the new ownership, CWC will continue to serve customers as part of the CSG group, working closely with the Chemifloc and GI Chemicals teams to align service, safety and sustainability standards.
Financial terms of the transaction are not being disclosed.
