Smart Water Monitoring

The Challenge

South African municipalities lose an estimated 25-35% of treated water to leaks, pipe bursts, and meter inaccuracies — a problem that costs billions of Rands annually. This particular municipality was losing over 30% of its treated water, with some areas experiencing 40%+ losses.

Leak detection was entirely reactive — crews were only dispatched after residents reported low pressure or visible leaks. By the time a leak was reported and located, thousands of litres had already been lost. Water quality monitoring was manual, with samples taken monthly and tested in a lab, meaning contamination events could go undetected for weeks.

Our Solution

We designed and deployed an IoT-based water monitoring system that provides real-time visibility into the entire water distribution network.

• IoT Sensor Network: Flow sensors, pressure sensors, and water quality probes deployed at key points across the distribution network
• Leak Detection AI: Machine learning algorithms that detect abnormal flow patterns and pressure drops in real time, alerting crews within minutes
• Water Quality Monitoring: Continuous measurement of pH, turbidity, chlorine levels, and temperature with automated contamination alerts
• Centralised Dashboard: Real-time map view of the entire network with drill-down into individual zones and sensors
• Mobile App for Field Crews: Alerts, work orders, and leak location guidance for maintenance teams
• Monthly Analytics Reports: Automated reports on water balance, loss trends, and water quality compliance

Results

Impact on Water Management

The system transformed the municipality from reactive to proactive water management. Leaks that previously went undetected for weeks are now identified within minutes. The AI learns normal patterns for each zone and flags anomalies — even small, slow leaks that would never trigger a resident complaint.

The water quality monitoring has been equally impactful. During one incident, the system detected a sudden pH drop in a treatment plant's output, alerting operators before contaminated water reached residents. The monthly analytics reports have become essential tools for infrastructure planning and budgeting.
