Real-time monitoring turns invisible leaks into actionable data.
When President Ramaphosa stood before the nation in February 2026 for the State of the Nation Address, the message was unmistakable: water is now the most urgent service delivery issue facing South Africa. Not electricity. Not roads. Water. And for millions of citizens—from the townships of Tshwane to the small towns of the Eastern Cape—that urgency is not a political talking point. It's a daily reality of dry taps, interrupted supply, and broken infrastructure.
The statistics are sobering. South Africa loses over 35% of its water to leaks—burst pipes, illegal connections, and aging infrastructure that bleeds billions of litres into the ground. In some municipalities, non-revenue water (water that is pumped but never paid for) exceeds 50%. At a time when dam levels are dropping and climate change is making rainfall patterns increasingly unpredictable, this is not just inefficiency. It's a national security risk.
The Invisible Crisis: Why We Can't Fix What We Can't See
The fundamental problem facing municipal water managers is visibility. A pipe bursts in a rural area—how long before anyone knows? A reservoir is overflowing—is anyone alerted before millions of litres are wasted? A community is illegally tapping a main line—is the impact on system pressure understood in real time?
Traditionally, the answer has been: wait for someone to report it. A resident notices water pooling. A concerned citizen calls the municipality. Days or weeks later, a team is dispatched. By then, the damage is done, the water is gone, and the cost has multiplied.
In 2026, this reactive model is no longer acceptable. And with the right technology, it's no longer necessary.
The Cost of Blindness
- R 7 billion+ lost annually in non-revenue water
- 35-50% of water lost before it reaches paying customers
- Days or weeks to detect leaks in remote areas
- Millions of rands in avoidable infrastructure damage and repair costs
The Digital Water Solution: IoT Meets Infrastructure
At MonyaTech, we've been working with municipalities and water utilities to deploy a new generation of monitoring tools—affordable, scalable, and designed for South African conditions. The core idea is simple: give every part of the water network a voice, and listen in real time.
Smart Sensors, Smart Network
We deploy low-cost, low-power IoT sensors at strategic points in the water network—reservoirs, pump stations, major pipelines, and high-risk areas. These sensors continuously monitor flow, pressure, and water quality, transmitting data via existing cellular networks. No expensive new infrastructure required.
The result: A burst pipe is detected within minutes, not days. A drop in pressure triggers an immediate alert. A reservoir reaching critical level automatically notifies the control room.
Mobile-First Control Room
Municipal managers don't sit in control rooms 24/7. Our platform puts the water network in their pocket. A simple mobile dashboard shows real-time status, alerts, and trends. A technician in the field gets notified of a suspected leak and can investigate immediately, with GPS coordinates and historical data at their fingertips.
AI-Powered Leak Detection
Our machine learning models analyse flow and pressure data to identify anomalies that human operators would miss. A tiny fluctuation that might indicate a developing leak? Flagged. A pattern that suggests illegal tapping? Alerted. The system learns what "normal" looks like for each part of the network and screams when something changes.
Predictive Maintenance
Instead of fixing pipes after they burst, what if you could predict which ones are about to fail? By analysing age, material, pressure patterns, and historical failures, our tools help municipalities prioritise maintenance budgets on the infrastructure most at risk. Proactive replacement costs a fraction of emergency repair.
Real Impact: A Mpumalanga Municipality Case Study
In 2025, a medium-sized Mpumalanga municipality approached us with a familiar problem: water losses exceeding 45%, frequent supply interruptions, and no clear understanding of where the water was going. They couldn't afford a complete pipe replacement, and they didn't have the staff to manually inspect hundreds of kilometres of network.
We deployed a phased IoT solution: 50 sensors across critical points, a central dashboard, and mobile alerts for the technical team.
Within six months:
- Non-revenue water reduced from 45% to 28%—a 17 percentage point improvement.
- 24 major leaks detected and repaired within 48 hours of occurrence, saving millions of litres.
- Response time cut from an average of 5 days to under 4 hours for critical alerts.
- Annual water savings estimated at 800 million litres—enough to supply over 15,000 households for a year.
The municipal manager told us: "For the first time, we're not guessing. We know exactly what's happening in our network, and we can act before it becomes a crisis. Our residents are seeing the difference."
Beyond Leaks: The Broader Digital Water Vision
While leak detection is the most urgent application, the same infrastructure enables a much broader transformation of municipal water management:
Water Quality Monitoring
Sensors can detect changes in turbidity, pH, and chlorine levels in real time, alerting authorities to contamination events before they reach consumers' taps.
Smart Prepaid Meters
IoT-enabled meters allow residents to manage their water usage and credit via mobile phone, while giving municipalities better revenue collection and demand management.
Transparent Reporting
Real-time data creates accountability. Citizens, councillors, and national government can see how the network is performing, building trust and enabling evidence-based oversight.
A National Priority, A Local Solution
The water crisis declared in SONA 2026 is not a problem we can outsource. It requires local solutions, built for local conditions, by people who understand South African municipalities—their constraints, their budgets, and their urgent need for practical, implementable technology.
MonyaTech is 100% South African. We've spent years working with public sector clients across all nine provinces. We understand the reality of municipal budgets, the challenge of skills constraints, and the critical importance of solutions that are robust, simple, and maintainable.
The technology to stop the leaks exists. The sensors are affordable. The networks are already in place. What's been missing is the will to deploy at scale—and a partner who can make it happen without decades of procurement cycles and consultant reports.
We're that partner. And we're ready to help South Africa turn off the tap on wasted water.
