What Celtic Water Solutions does

Celtic Water Solutions, founded in 2002 in Tuam, Co. Galway, Ireland and now operating as Culligan Home (Ireland) Limited following a December 2023 legal rebranding, is an Irish water treatment specialist serving residential, commercial, and industrial customers across Ireland. Its core offering centres on water softening systems (Culligan Arc, Minimax M3, HE, and CWS Clack series using American-made Clack valves and twin-cylinder non-electric technology), reverse osmosis filtration units (Culligan Direct Flow, 6-Stage, Compact with remineraliser), point-of-use filters (Culligan So Clear, Doulton ceramic, Oasis Green, Wrapped Carbon), instant boiling and Tri-Flow taps, and office water coolers and dispensers. Underlying technologies include ion exchange water softening, meter-regeneration, WiFi-enabled i-Lid smart monitoring via the myHarvey app, and silver-stabilised hydrogen peroxide tank disinfection.

The company monetises through a hybrid model: one-time equipment sales with bundled professional installation, recurring subscriptions (Culligan Complete filter rental at €15/month, office water cooler rentals), annual servicing contracts, consumables (softener salt €9.99-€50+, RO membranes €48-€82, replacement filters €15-€140), and tank cleaning services (€300-€2,000 per job). Distribution combines a consultative field sales force, an in-house inside sales team with regional phone lines across five Irish regions, an e-commerce storefront, and a nationwide fleet of installation and service technicians. The customer base spans 50,000+ households over 20 years alongside enterprise accounts in beverage, healthcare, technology, transportation, and government.

Following the June 2022 acquisition by Culligan International (90 countries, 13,000+ global employees) and the October 2023 acquisition of Gulp Water Filters, the company has consolidated the legacy Celtic Water Solutions, Watercare, and Simply Water brands into a single Culligan-branded Irish entity. With 11-50 employees and a multi-office footprint (Claregalway HQ, Tuam, Dublin, plus regional sales coverage in Cork, Meath, and Donegal), the business positions itself as the Culligan group's residential and light-commercial water treatment vehicle for the Irish market.
