Challenges

Aging pipe infrastructure with mixed materials (cast iron, PE, steel) leads to frequent joint leakage. Traditional manual inspection is inefficient and unable to pinpoint leaks promptly.
Extensive network coverage with varying burial depths and numerous branch nodes creates large monitoring blind spots, leaving remote pipe segments unmanaged for extended periods.
Conventional loss assessment methods like minimum night flow analysis lack precision to distinguish metering errors from actual leakage. DMA (District Metered Area) zoning retrofits are costly and time-consuming.
Risks of secondary water contamination — chlorine decay, biofilm growth, and dead-end stagnation — lack real-time monitoring, making incident tracing extremely difficult.
Existing SCADA systems operate as data silos, with no unified operational view. Hydraulic models are disconnected from field measurements, undermining evidence-based dispatch decisions.

System Overview for Smart Water Management

This system deploys intelligent monitoring terminals at critical network nodes like DMA boundaries and pump stations to collect pressure, flow, and water quality data. Data is transmitted wirelessly to a cloud platform integrating GIS and big data analytics for comprehensive visualization and intelligent management of the water supply network.

Core capabilities include DMA-based leak analysis, rapid burst pipe early warning, and end-to-end water quality monitoring. This integrated approach effectively reduces network losses and ensures a safe and reliable urban water supply.

Core System Functions

Real-Time Network Pressure Monitoring

High-precision pressure transmitters at critical nodes continuously build a network-wide pressure distribution profile. This data is crucial for maintaining optimal hydraulic performance across the entire urban water supply network.

The system automatically detects pressure anomalies to identify burst pipes and valve failures, triggering tiered alerts for rapid localization. Furthermore, this pressure data feeds hydraulic model analysis to optimize supply dispatch and balance network pressure.

DMA Zone Flow Metering and Leak Analysis

High-accuracy electromagnetic flowmeters at District Metered Area (DMA) boundaries independently meter supply volume, consumption, and losses per zone. This forms the foundation for effective water loss management in the water supply network.

Minimum Night Flow (MNF) analysis automatically calculates leakage levels per DMA, pinpointing high-loss zones. By combining pressure correlation and acoustic detection, the system achieves a remarkable 50-meter leak localization accuracy.

Online Water Quality Monitoring from Plant to Tap

Water quality analyzers are deployed at strategic points from plant outlets to network endpoints. They provide real-time monitoring of key parameters like residual chlorine, turbidity, and pH with automatic threshold-based alerts.

Advanced chlorine decay modeling predicts endpoint chlorine levels, enabling utilities to detect secondary contamination risks early. This end-to-end water quality assurance is vital for safe drinking water delivery.

Intelligent Early Warning and Emergency Response System

Sudden pressure drops instantly trigger burst pipe alerts, complete with automatic impact assessment and valve closure recommendations. Similarly, water quality anomalies trigger contamination warnings linked to predefined emergency response workflows.

Multi-channel alert delivery via SMS, mobile APP, and central dashboard ensures immediate operator awareness and facilitates a coordinated response, minimizing the impact of any network incident.

GIS Unified Network View for Operations

The platform provides a single map view integrating network topology, asset inventory, real-time sensor data, and maintenance history. This GIS unified view is the operational command center for the online monitoring system.

Powerful spatial analysis tools enable impact zone assessment and valve operation simulation. A companion mobile app grants field crews direct access to network data and dispatched tasks, bridging office and field operations.
