Wuzhipa Water Plant becomes China's first HarmonyOS smart waterworks

Wuzhipa Water Plant, the first smart waterworks in the western part of Shenzhen, completed a HarmonyOS upgrade March 9, becoming the country’s first HarmonyOS-enabled smart water plant. The retrofit links full-process production, robot inspections, water-quality monitoring and equipment operation through unified, real-time data connectivity.

Located in Bao’an District, Wuzhipa is a deep-treatment facility with a design capacity of 300,000 cubic meters per day and is responsible for supplying water to about 700,000 residents in Bao’an. The plant had already implemented end-to-end intelligent control before the HarmonyOS upgrade. The recent smart transformation focused on removing remaining barriers in system and equipment connectivity while upgrading security and autonomous control capabilities.

Shenshui Bao’an Water Group, the operator of Wuzhipa, introduced HarmonyOS PLC controllers, smart terminals and the B-LINK Flash Link solution to achieve cross-generation interoperability and trusted autonomous control. The project also deployed WaterHMOS — the nation’s first water-sector intelligent platform built on the open-source HarmonyOS — enabling smart water management and device integration.

Using the WaterHMOS platform, the Wuzhipa plant added smart manhole-cover monitoring devices and intelligent hydrant monitors. Manhole units now report liquid level, tilt and overflow status in real time; hydrant monitors sense pressure, cap angle and valve-opening status. All sensor data are uploaded via the Harmony network in seconds, shifting the operation model from passive inspections to proactive alerts.

The HarmonyOS upgrade also introduced Harmony-powered inspection robot dogs and drones to carry out tasks in high-risk areas without sending personnel into danger. By integrating Harmony PLCs and the Harmony control platform, Wuzhipa now aggregates production data and visual feeds across three plants and one station in the Songgang area, enabling unified monitoring and coordinated command.

Operational benefits are already measurable at Wuzhipa. AI applications now cover more than 90% of scenarios, with 100% of plant data interlinked. Overall operational efficiency has improved by over 30%, and false alarms have fallen by 30%. AI optimizations have reduced inspection labor hours by 25%, and office energy consumption has declined by 10%. The unified data foundation also allows maintenance staff to quickly establish secure connections and task assignments by tapping on-site equipment with a Harmony mobile terminal using the B-LINK feature.
