i2O Advanced Pressure Management

i2O Water is a UK-based maker of pressure management technology for water utilities, headquartered in Woolston near Southampton. In June 2026 its assets were acquired by GWF AG, a water and gas metering group based in Lucerne, Switzerland, and the i2O technology is now offered on the GWF solution pages.

The solution combines i2O loggers that record pressure, flow and temperature, a cloud network-monitoring platform with alarms, and PRV and pump controllers. A patented self-learning function holds a stable target pressure at the critical point of a zone. Referenced utilities include South East Water, Manila Water and City of Cape Town.

• Advanced Pressure Management: remote pressure control with automatic optimization for water networks.
• i2O Loggers: record pressure, flow and temperature, with over-the-air upgrades and hot-swap.
• Network Monitoring: dashboards and alarms for pressures and flows, including third-party loggers.
• Remote Control: basic, timed (up to 96 settings per day) and flow-modulated control of PRVs and pumps.
• Automatic Pressure Optimization: patented self-learning control of the critical-point pressure.
• Cloud platform: multi-user web access to network data.

Pressure optimization of DMAs in provincial water supply companies in Vietnam to cut leakage and burst frequency. Retrofit of existing PRVs on trunk mains with remote controllers. Pressure and flow monitoring of critical points in large urban networks such as Ho Chi Minh City.

Remote and automatic pressure control reduces the need for site visits to valves. Stable target pressure at the critical point supports lower leakage and fewer bursts. Hot-swap loggers inherit the configuration of the replaced device, shortening maintenance. The controllers work with any PRV brand and the monitoring accepts third-party loggers.

Non-revenue water and energy cost push utilities toward active pressure management. Vietnamese and Southeast Asian utilities are expanding district metered areas, which creates demand for controllable PRVs and logger networks. A Manila Water reference shows the technology is already used in the region.

i2O Water Ltd is based in Woolston, Southampton (UK); its assets were bought by GWF AG (Lucerne, Switzerland) in June 2026, and the brand continues under GWF. Datasheets on the page carry 2026 versions.
