-
Replacing some routine monitoring and data analysis tasks, such as automatically detecting water quality anomalies and predicting pipeline leaks, reducing manual inspections and data recording.
-
Replaced manual operation and scheduling tasks of pumping stations, automatically adjusts pump speed to match demand, reducing on-site intervention.
-
Replaced equipment fault diagnosis and maintenance planning by analyzing sensor data for early warnings, reducing downtime.
-
Partially replaced energy management tasks, automatically identifying energy-saving opportunities, reducing manual energy audits.
-
Replaced some manual work in water quality sampling and lab analysis, enabling continuous monitoring and early warning of exceedances.
- Remote monitoring automatic data collection and abnormal alarm analysis
- Automatic generation and archiving of water quality test reports
- AI planning and scheduling of routine equipment inspection routes.
- Trend analysis and predictive maintenance of historical operational data
- Customer billing inquiries and basic issue responses
- AI-assisted leak detection and pressure optimization for water networks, improving repair efficiency
- Digital twin simulates different operating conditions to optimise treatment process parameters
- Real-time water quality sensor data combined with AI alerts for rapid pollution event response
- In-pipe inspection using drones/robots reduces manual risk.
- AR glasses enable remote expert guidance for on-site repairs, reducing downtime
- On-site judgment and handling of emergencies like sudden pipe bursts or pump station failures
- Environmental compliance interpretation and regulatory communication
- Construction coordination and safety supervision in old pipeline network renovation
- Inter-agency emergency coordination and public communication
