GWF AG, the Swiss manufacturer of utility metering and smart water technology, announced that it has acquired the assets of UK-based i2O Water Limited, a specialist in pressure optimization and leakage reduction for water distribution networks. i2O’s data loggers, pressure-reducing valve controllers, and adaptive optimization software are deployed across more than 100 water utilities in over 45 countries, serving an estimated 50 million end users. Financial terms of the transaction were not disclosed, and production will continue at i2O’s existing site in Southampton, England.
From Advisory Insight To Autonomous Valve Control
GWF said the deal pairs two technologies it considers complementary. GWF BALANCE, the company’s own pressure-optimization software, forecasts the optimal zone pressure across a distribution network, while i2O’s PRV controller and Adaptive Open Loop technology then execute that target autonomously at the valve. GWF describes this as closing the loop between advisory analysis and near real-time intervention, rather than leaving utilities to act manually on software-generated recommendations.
i2O’s UK Roots And Global Installed Base
i2O Water was founded in 2005 and built its business around what it calls Advanced Pressure Management, a technology platform aimed at cutting leakage, reducing burst frequency, and extending the working life of aging pipe networks. According to Companies House, the company remains registered in Southampton. Its client base spans water utilities across the UK as well as international markets including parts of Asia and Latin America.
A Second Change Of Ownership In Five Years
This is i2O’s second change of ownership in five years. In June 2021, Atlanta-based Mueller Water Products acquired i2O Water for approximately $20 million in cash, with plans to fold the technology into its Sentryx digital platform and introduce i2O’s products to North America, a market where i2O had no prior presence. Neither GWF nor Mueller has issued a public statement explaining the rationale for the divestment, and it is described in GWF’s announcement specifically as an asset acquisition rather than a purchase of the legal entity.
GWF’s 125-Year Push From Metering Into Network Intelligence
GWF AG is a family-owned manufacturer headquartered in Lucerne, Switzerland, with roots dating to 1899 in water, gas, heat, and electricity metering. The company says it now employs around 350 people across nine locations worldwide and holds more than 150 patents. In recent years GWF has pushed beyond hardware into software and data services, including its INFINIO cloud platform and the GWF BALANCE pressure-analytics tool that forms the basis of this acquisition’s technical pitch.
“I am truly excited to welcome i2O Water into GWF,” said Florian Strasser, CEO and Chairman of GWF AG, in the company’s June 2026 press release announcing the acquisition.
Southampton Production And Customer Continuity Preserved
GWF said existing i2O customers and partners can expect continuity of service through the transition, supported by what it describes as expanded engineering resources and longer-term investment than the unit previously received. The existing i2O team will be integrated into GWF’s UK business unit, led by Gary Vincent, Managing Director of GWF Ltd. Production of i2O’s hardware will remain at the company’s current Southampton facility rather than relocating to Switzerland.
Pressure Management Sits Inside A Tightening UK Regulatory Target
The acquisition lands as UK regulator Ofwat pushes water companies toward sharper leakage cuts. Under its 2025-30 price determinations, Ofwat has set a sector-wide target to reduce leakage by a further 17 percent from 2024-25 levels, backed by more than £700 million in cost allowances for pressure management, leak repair, and main replacement. Ofwat reports that leakage in England and Wales is now at its lowest level on record, though the sector has committed to halving it from a 2017-18 baseline by 2050, a goal that depends heavily on technologies like pressure-reducing valve control.
Consolidation Accelerates Across Smart Water Technology
The deal fits a broader pattern of larger instrumentation and metering groups acquiring niche pressure- and network-monitoring specialists. In the United States, water-market research firm Bluefield Research has estimated that non-revenue water costs utilities more than $6.4 billion annually, with nearly one in five gallons of treated water lost before it is billed. Just weeks before the GWF-i2O deal, Badger Meter agreed to acquire UK sewer-monitoring firm UDlive for $100 million plus contingent consideration, folding it into its BlueEdge suite alongside its existing SmartCover platform.
