Leak Detection, NRW water monitoring and control

Tailor made solution for utility companies to monitor and control pressure, flow, level in their networks

ThingsLog NRW is designed to address Non-Revenue Water (NRW) challenges by providing a DMA analytics platform to reduce non-revenue water through advanced leak detection, pressure monitoring, and control capabilities. 

It integrates flow monitoring, pressure management, and tank level monitoring with advanced AI algorithms for leak detection to optimize water distribution networks, reduce water losses, and improve operational efficiency.

The final goal is to improve the water balance of the utility operator, to allow timely leak detection and to reduce the water loss.

Understanding Non-Revenue Water (NRW)

Non-Revenue Water refers to the difference between the volume of water put into the distribution system and the volume billed to customers. NRW has three components: real losses (physical leaks and pipe bursts), apparent losses (meter inaccuracies, illegal connections, data errors), and unbilled authorized consumption (fire fighting, network flushing). Globally, NRW averages 25–30% but can exceed 50% in aging networks. For utilities, every percentage point of NRW reduction represents significant cost savings in water production, treatment, and energy.

The ThingsLog Approach to NRW Management

District Metered Area (DMA) Monitoring

The network is divided into DMAs — isolated zones with defined entry and exit points. ThingsLog installs flow and pressure loggers at zone boundaries. The platform automatically calculates the water balance for each DMA, comparing inflow against metered consumption to identify excess losses. DMA monitoring is the foundation of any effective NRW programme: without knowing where losses occur at a zone level, field resources are deployed inefficiently across the entire network. ThingsLog supports both permanent DMA monitoring installations and temporary step-testing configurations for initial loss assessment surveys.

Minimum Night Flow Analysis

At night (typically 2–4 AM), legitimate consumption is minimal. Any excess inflow detected during this period is a strong indicator of background leakage. ThingsLog automatically calculates MNF for each DMA nightly and alerts operators when it exceeds the expected baseline.

Pressure Management for Leak Reduction

Higher network pressure increases both leak rates and burst pipe frequency. ThingsLog monitors pressure at multiple points and recommends or automatically adjusts PRV setpoints to maintain service levels while minimizing pipe stress. Each 10m reduction in average zone pressure can reduce leak rates by 4–6%.

Burst Detection and Localization

Sudden pressure drops or unexpected flow increases trigger immediate alerts. The platform correlates data from multiple monitoring points to narrow the likely burst location, reducing the search area for field crews from kilometres to a few hundred metres.

Technical Integration

The ThingsLog NRW solution integrates with existing utility infrastructure: Modbus flow meters and pressure transmitters connect directly to data loggers; existing SCADA systems receive data via API or MQTT; GIS platforms can overlay monitoring data on network maps; billing systems integrate via API for apparent loss analysis.

ROI of NRW Monitoring

Utility Size Annual Water Production 30% NRW Cost of Losses (at €0.5/m³ production cost) Payback Period for ThingsLog Solution
Small (2M m³/yr) 2,000,000 m³ 600,000 m³ €300,000/yr 6–12 months
Medium (10M m³/yr) 10,000,000 m³ 3,000,000 m³ €1,500,000/yr 3–6 months
Large (50M m³/yr) 50,000,000 m³ 15,000,000 m³ €7,500,000/yr 1–3 months

Standards and Compliance

ThingsLog NRW monitoring aligns with the IWA (International Water Association) water loss methodology and supports reporting requirements for EU Water Framework Directive compliance. The platform generates standardized reports on water balance, NRW components, and infrastructure performance indicators (ILI — Infrastructure Leakage Index).

Workforce and Operational Benefits

Beyond the direct financial savings from reduced water losses, ThingsLog NRW monitoring transforms day-to-day operations for utility staff. Control room operators gain a live overview of every monitored DMA, replacing manual daily inspection rounds with exception-based management — staff focus attention only on the zones flagging anomalies. Field crews receive precise location data before departing the depot, reducing wasted travel to areas without active leaks. Management receives automated weekly water balance summaries and trend reports without manual data compilation. The combined effect is a leaner, more responsive operations team capable of managing a larger network with the same headcount.

Getting Started with NRW Monitoring

A typical NRW monitoring project begins with a network audit to identify existing DMA boundaries, available metering points, and current data gaps. ThingsLog can support this assessment remotely using network schematic data provided by the utility. Following the audit, a pilot DMA is selected and instrumented, providing the first real-time water balance data within days of installation. Results from the pilot — including identified leakage volumes and pressure profiles — form the business case for a full network rollout. ThingsLog supports utilities through the full project lifecycle: device supply, installation guidance, platform configuration, operator training, and ongoing technical support.
