You manage water across dozens — maybe hundreds — of facilities. You want a water leak detection system. This guide tells you what to look for, what questions to ask, and what implementation actually involves.
One more thing before we start: a good water leak detection system is the single most effective tool for achieving sustained water loss reduction. Not behaviour change programmes, not water-saving fixtures, not monthly meter audits. A properly deployed IoT monitoring system — running continuously, alerting in real time, visible across all sites — is where the 15% savings actually comes from.
The Multi-Facility Water Problem Nobody Talks About
If you manage 50, 100, or 500 locations, you almost certainly have active water leaks right now that nobody has found yet. This is not a hypothesis — it is a near-universal finding when organisations first deploy real-time monitoring. Industry data consistently shows that 15–25% of water entering a facility network never reaches its intended use.
The cost of this is not just the water bill. Undetected leaks drive:
- Structural damage (average claim: €8,000–€40,000 per incident)
- Mould and air quality issues in enclosed spaces
- Insurance premium increases after repeated claims
- ESG reporting gaps — you cannot report water reduction you cannot measure
- Reactive maintenance costs that are 3–5× higher than proactive prevention
What a Water Leak Detection System Is (And Is Not)
A water leak detection system is not a point sensor. It is not a smart faucet. It is not a moisture alarm under your server room floor — though those have their place.
A proper system has three core layers:
- Data acquisition — smart meters, flow sensors, and pressure loggers installed at every relevant point in your water infrastructure (mains entry, risers, sub-meters, critical zones)
- Analytics engine — algorithms that detect anomalies in real time: night-flow patterns, pressure variance, consumption spikes, zone imbalances
- Management platform — a centralised dashboard where your team sees all facilities, receives alerts, investigates incidents, and generates reports for finance, sustainability, and compliance
ThingsLog is built on carrier-grade utility infrastructure — the same technology that national water utilities use to manage millions of connections — adapted and made accessible for any organisation managing multiple facilities. You get the reliability and accuracy of utility-grade hardware, without the utility-scale procurement process.
Water Loss Reduction: What 15% Looks Like Across Your Portfolio
The number that matters: ThingsLog customers achieve an average 15% reduction in total annual water consumption. Here is what that means depending on your portfolio:
- A retail chain with 150 stores (avg. €2,500/yr water cost each): €56,250 saved per year
- A hotel group with 40 properties (avg. €20,000/yr each): €120,000 saved per year
- A corporate real estate portfolio (30 office buildings, avg. €8,000/yr): €36,000 saved per year
These figures cover metered consumption only. Add avoided damage and reactive maintenance costs and the ROI case becomes very straightforward to make to a CFO.
Who Uses a Water Leak Detection System
Any organisation with multiple facilities and a water bill. ThingsLog works across:
- Retail chains — store networks, distribution centres, HQ campuses
- Hotel & hospitality groups — high water intensity, 24/7 operation, brand risk from visible damage
- Gas station networks — forecourt, car wash, underground infrastructure monitoring
- Hospitals & healthcare — compliance-critical environments with complex pipe networks
- Manufacturing & industrial — process water, cooling loops, high-pressure systems
- Airports & logistics hubs — massive footprints, zero downtime tolerance
- Corporate real estate — office portfolios, mixed-use campuses, shared services facilities
- Water utilities — district metering, non-revenue water reduction, network optimisation
The underlying principle is the same regardless of sector: you cannot reduce what you cannot measure. A water leak detection system gives you the measurement layer. The reduction follows.
7 Questions to Ask Any Water Leak Detection System Vendor
- Does the system handle multi-site, centralised management? If not, you will end up with 100 dashboards instead of one.
- What is the minimum detectable leak rate? Good systems detect from 0.01 L/min — enough to catch slow seepage before it becomes structural damage.
- How does alert routing work? Alerts should go to the right person at the right site, not to a generic inbox nobody monitors.
- What connectivity does it use? NB-IoT, LoRaWAN, 4G/5G — and what happens when connectivity drops?
- How is historical data stored and accessible? You need at least 24 months of data for ESG reporting and trend analysis.
- Does the platform integrate with your existing systems? ERP, BMS, FM software — your data should flow where your team already works.
- What does implementation actually involve? Hardware install, commissioning, training — and how long before you see the first alerts?
What Implementation Actually Involves
ThingsLog deployments follow a structured process that minimises disruption and maximises time-to-value:
- Site survey & baseline — we map your existing water infrastructure and establish a consumption baseline per site (1–2 weeks)
- Hardware installation — smart meters and sensors installed at mains and key sub-meter points; typically half a day per site with no downtime
- Platform onboarding — your team gets access to the centralised dashboard; alerts configured per site and role
- Baseline verification — first 2–4 weeks of live data used to validate baselines and tune anomaly thresholds
- First leak detections — typically within the first week of operation on any new site; the savings start immediately
- Reporting & optimisation — monthly consumption reports, site benchmarking, and ongoing threshold refinement
Most organisations start with a pilot of 5–10 sites, generate measurable ROI data within 60 days, and then use that data to justify full rollout. The pilot pays for itself.
Ready to Make Water Loss Reduction Real?
ThingsLog brings carrier-grade water leak detection to any organisation managing facilities — not just utilities. If you have a water bill and 10 or more locations, the economics work in your favour.
Get ThingsLog. Achieve 15% water savings. And yes — your plumbers will call you less. That is the point.
