Water leak detection software: detect leaks before they cost you
You typically discover a water leak only when the damage is already done: when the bill arrives, when a pipe has burst, or when water damage has spread across a floor you didn't even know was at risk. With Willie's water leak detection software, you detect leaks in real time, receive intelligent alerts 24/7, and protect both your infrastructure and your budget.
Willie water leak detection software: key features
Detect leaks in under 30 minutes
- Willie continuously monitors your water network using connected sensors installed on your existing meters. Data is collected and transmitted every 15 minutes, giving you a near real-time picture of your consumption across all sites.
The platform uses artificial intelligence to analyze consumption patterns and identify anomalies. By comparing observed flow rates against reference models, the system can detect the smallest deviation that may indicate a leak — including those too small to trigger conventional alarms. When the software detects a leak, it immediately triggers an alert to your team so they can act before water damage spreads.
Willie can also locate leaks using multi-meter triangulation, narrowing down the affected section of your network precisely. This dramatically reduces the time your teams spend searching for the source of the problem and lowers repair costs by targeting only the affected pipes.
Key detection capabilities: - Continuous analysis of flow rates and consumption patterns across all connected devices
- Precise location of leaks through multi-sensor triangulation across your pipe network
- Detection of small water leaks that would typically go unnoticed for weeks
- Identification of anomalies caused by faulty equipment, abnormal pressure drops, or unusual temperature changes
- Full history of detected events to support predictive maintenance and future repairs
Customizable alerts to prevent water damage
- Not every alert requires the same level of urgency. Willie lets you configure your notification system to match your organization's structure and priorities. You control who receives which alert, through which channel, and at what threshold. You can now prevent water damage without drowning your teams in unnecessary notifications.
Alert configuration options include: - Custom notification schedules: set active hours, on-call contacts, and escalation chains
- Multiple alert channels: SMS, email, and API integrations with your existing tools
- Graduated criticality levels, from informational warnings about small leaks to emergency alerts requiring immediate action
- Acknowledgment tracking: monitor who has seen each alert and what corrective action has been taken
- This level of control means that when a water leak is detected at 2 AM in a critical location, the right person is notified immediately — not the next morning during a routine check.
Monitor every site from a single dashboard
- Willie's software platform was built for organizations that manage multiple locations. Whether you oversee 5 sites or 500, you can monitor all your data, alerts, and consumption reports from a single consolidated dashboard.
The platform gives you: - Real-time data from all connected sensors and meters, refreshed every 15 minutes
- Multi-site dashboards with customizable views by location, department, or building floor
- Automated compliance reports (including PSH, CSRD, DPEF, and DREAL formats) generated without manual effort
- AI-assisted management to anticipate budget drift and contractual deviations before they become problems
- Open API for integration with your ERP, BMS, or CMMS systems
- The ability to connect all your sites into one system means you can compare performance across locations, identify which buildings waste the most water, and prioritize repairs where they'll have the greatest impact.
Willie vs. traditional remote reading
The hidden cost of leaks
Water waste is one of the most underestimated operational expenses in any facility. Small water leaks that go undetected for days or weeks can waste hundreds of gallons before anyone notices. Across multi-site organizations (whether in construction, industry, hospitality, or healthcare), the cumulative cost of small leaks can run into tens of thousands of dollars per year.
Beyond the financial impact, water damage caused by undetected leaks can compromise the structural integrity of buildings, damage equipment, disrupt production, and create significant health and safety risks. In care facilities, for example, a leak near a kitchen or boiler room can trigger a full service shutdown. On a construction site, a leak in a temporary water network can halt the entire operation.
The challenge is that most leaks (especially small water leaks hidden inside walls, under floors, or along underground pipes) are invisible to the naked eye. Without the right system in place, you simply cannot detect them in time to prevent damage.
That's exactly what Willie's water leak detection software is built to solve.
A plug-and-play system installed in minutes
One of the biggest barriers to adopting leak detection technology is typically the installation process. Traditional remote metering solutions require specialist plumbers, electrical wiring, water shutoffs, and hours of work per meter — at a cost of $300 to $500 per installation point.
Willie takes a completely different approach. The Willie Smart Meter module is a non-intrusive device that clips magnetically onto your existing meters in under 10 minutes, with no tools, no drilling, no soldering, and no water cutoff required. It is compatible with all pulse-output meters regardless of brand or age.
The module runs on a 10-year integrated battery, so there's no need for electrical connection or ongoing maintenance. It connects via LoRaWAN, NB-IoT, or 4G, ensuring reliable data transmission even in basements or underground locations where standard GSM networks typically fail.
Once the hardware is installed, your software dashboard is configured and your team is trained in under an hour. The entire deployment, from audit to live monitoring, is completed in 14 days.

Sector-specific applications
Water leak detection needs vary significantly depending on the industry. Willie adapts its alert system and monitoring logic to the specific risks of each sector.
Construction sites
- They face unique challenges: temporary water networks are inherently vulnerable to leaks, unauthorized use, and sudden pressure drops. Willie monitors provisional pipes around the clock, detects unauthorized water use, and sends immediate alerts if a cutoff occurs that could shut down work.
Care facilities (EHPAD, clinics)
- They require priority monitoring of critical services such as kitchens, boiler rooms, and sanitation areas. A leak in these locations can create serious hygiene risks or force service interruptions. Willie delivers graduated alerts based on criticality to flag potential health hazards before they escalate.
Industrial facilities
- They rely on high-frequency monitoring to protect complex production processes. Willie provides preventive maintenance alerts for pumps and valves, and helps prioritize water use in line with regulatory restrictions. This allows operations to continue even during water stress periods.
Hotels and hospitality venues
- They benefit from zone-specific alerts that differentiate between guest rooms, kitchens, spa areas, and back-of-house infrastructure. Willie also ramps up monitoring during peak occupancy periods, when the risk of undetected small water leaks causing damage to guest areas is at its highest.
