What Global Water Solutions does
Global Water Solutions Ltd. (GWS) is a manufacturer of pressure tanks and water treatment products founded in 2003 and headquartered in St. Helier, Jersey (operating through a UK-incorporated private limited company). The company operates as a wholly-owned subsidiary of South Korea's GS Engineering & Construction, held through its Spanish subsidiary GS Inima; that holding is itself subject to a pending $1.2 billion acquisition by Abu Dhabi National Energy Company (Taqa) expected to close in 2026. GWS claims to be the largest global manufacturer of pressure tanks and water treatment products, serving customers in over 100 countries through seven dedicated regional websites spanning the UK, APAC, Europe, India, Latin America, the Middle East, and South Africa.
The company's product portfolio is organized into two divisions: Water Movement and Water Enhancement. Water Movement includes an extensive steel pressure tank portfolio (PressureWave, SuperFlow, Max, Challenger, E-Wave, UltraMax, ASME-certified vessels, and PerenneFlow), anti-Legionella tanks featuring patented Flow-Thru™ technology in both steel and composite variants, harsh-environment tanks (InoxFlow stainless, M-Inox, All-Weather with patented Plasteel™ shells, and C2-Lite CAD composite), hot water expansion tanks (ThermoWave, HeatWave, SolarWave), HydroGuard shock arrestors, PumpWave electronic pump controllers, and ProLine uPVC column pipes. Water Enhancement comprises the Quatreau® multi-function tap line (TouchTap, SmartTap, HydreauBar, The Q), OneStop+™ microcrystal anti-scale and ZeroSpot™ deionized rinse systems, AquaWave™ reverse osmosis systems (Premium, Premium Eco, Pro G500 up to 400 GPD), filtration systems (CounterWave, UltraWave), filter housings, replacement cartridges, and BioWave™ bacterial grey-water treatment.
GWS runs a sales-led B2B go-to-market with quote-based pricing rather than public e-commerce, supported by regional websites, active trade show participation (EuroCucina 2026, Plumbex India, Decorex Cape Town 2026), content marketing via blog and a tank-sizing calculator, and organic social engagement. Hardware sales across residential, commercial, and industrial segments (pressure boosting, water storage, hospitality, mining, marine, food service) form the revenue base. Manufacturing is conducted at an ASME-accredited facility; a wholly-owned Italian subsidiary in Reggio Emilia was established to support European distribution. Financials including revenue, headcount growth, and contract values are not publicly disclosed.
