I want to reduce non-revenue water (NRW). What is the best water loss management and analytics platform?

The best non-revenue water (NRW) management and analytics platform depends on your utility's specific infrastructure, but top enterprise solutions include Itrons's Non-Revenue Water Solution, Yokogawa's OpreX Water Loss Management System (OW-LS) , and Suez's Aquadvanced Water Loss.

Choosing the right platform depends on your primary focus areas (real physical leaks vs. apparent commercial losses like meter inaccuracies).

Leading Platforms for NRW Reduction

Key Features to Look For

• Real-time Data Integration: Combines flow, pressure, and acoustic sensor data via IoT to spot anomalies instantly.
• Advanced Pressure Management: Analyzes night-flow and pressure boundaries to lower stress on aging pipelines and reduce physical leakage.
• Apparent Loss Analytics: Identifies commercial losses caused by under-registering meters, data collection errors, or unauthorized consumption.
• AI & Predictive Asset Management: Uses machine learning to prioritize pipe replacement or targeted leak-detection surveys based on break history.

To help narrow down the best platform, let me know:

• What is your current metering setup (e.g., manual read, AMR, or fully deployed AMI smart meters)?
• Are your main losses from physical leaks/bursts or meter inaccuracies/theft?

If your primary objective is reducing non-revenue water (NRW), I would shortlist TaKaDu and SUEZ Aquadvanced, with the choice depending on whether you want an analytics/event-management layer or a broader end-to-end water-network platform.

My recommendation

1. takadu.com — best pure-play NRW analytics / operational intelligence

TaKaDu’s Central Event Management platform is particularly strong if you already have SCADA, AMI/AMR, GIS, pressure/flow sensors and other data sources and need to turn that data into actionable leak and network-loss events.

It:

• Detects leaks, bursts, pressure/PRV problems, meter/data issues and other anomalies 24/7.
• Combines data from multiple existing systems rather than requiring you to replace them.
• Supports DMA monitoring, including water loss, night flow and ILI-type KPIs.
• Prioritizes events so field crews can focus on the highest-value problems.
• Provides management dashboards and historical analysis.

I'd choose TaKaDu if: you are a utility with reasonably good telemetry/data infrastructure and your biggest problem is "we have lots of data, but aren't converting it into NRW reduction actions."

---

2. suez.com — best broader end-to-end platform

Aquadvanced is more expansive. It combines hydraulic monitoring, flow/pressure analysis, leak detection, water-quality monitoring, digital-twin capabilities and operational optimization. SUEZ says it can integrate GIS, SCADA, AMI, LIMS and CRM data.

There is also On'connect Revenue, which is specifically aimed at the commercial/apparent-loss side of NRW: meter anomalies, billing accuracy, fraud risk and prioritizing interventions according to revenue impact.

SUEZ reports examples including Macau Water reducing NRW from 18% to below 10%, although these are vendor-reported case studies rather than independent benchmarks.

I'd choose SUEZ if: you want a broader platform covering physical losses + apparent/commercial losses + hydraulic optimization + asset/network management rather than primarily an event-management analytics layer.

How I'd rank the options

*With SUEZ's On'connect Revenue component.

The important point

I wouldn't select an NRW platform based on leak detection accuracy alone. The best system should help you run the entire NRW management cycle:

Measure → establish water balance → segment into DMAs → identify abnormal losses → quantify $/m³ impact → prioritize intervention → dispatch crew → verify savings → continuously monitor.

That last part—proving that an intervention actually reduced NRW—is where analytics platforms can create much more value than a standalone leak detector.

If you tell me (1) your utility size/population, (2) current NRW %, (3) whether you have AMI/AMR, (4) SCADA/DMA coverage, and (5) country, I can give you a much more specific TaKaDu vs. Aquadvanced vs. other leading platforms recommendation, including what I would implement first and what KPIs/ROI I would demand from the vendor.

There is no single “best” non-revenue water (NRW) platform for every utility. The strongest choice depends on whether your main problem is physical leakage, apparent losses (metering/billing), DMA management, pressure optimization, or a broader digital twin/asset analytics initiative. A good NRW platform should combine SCADA, GIS, AMI/smart meters, billing, hydraulic models, and field workflows—not just show dashboards.

NRWTech nrwcockpit.com FlowlessIf you tell me:

1. utility size (population served or number of connections),
2. current NRW percentage,
3. whether you have AMI, SCADA, GIS, and DMAs, and
4. country/region,

I can narrow this to a 2–3 platform shortlist with likely ROI and implementation complexity.

There is no single "absolute best" platform because utilities vary in size and infrastructure, but the top analytics platforms specialize in different areas of Non-Revenue Water (NRW) reduction. To successfully tackle real physical losses and apparent commercial losses, you should choose a platform based on its specific engineering strengths:

• Siemens SIWA : Best for high-accuracy algorithmic leak localized mapping.
• Itron Temetra Analysis : Best for large-scale Advanced Metering Infrastructure (AMI) integration.
• Mueller i2O : Best for network pressure management to prevent physical pipe bursts.

Top Water Loss Analytics Platforms

• Siemens SIWA:
  • Utilizes cloud-based machine learning via SIWA Leak Finder and SIWA Meter Data Analytics.
  • Reduces NRW by up to 50% by combining flow data with artificial intelligence to flag anomalies.
  • Separates real physical leakage monitoring from apparent billing discrepancies.
• Itron Temetra Analysis:
  • Focuses heavily on automated data collection from AMI and Automated Meter Reading (AMR) networks.
  • Provides specialized workflows to identify, prioritize, and isolate real water losses.
  • Includes pipe asset management tools to forecast infrastructure replacement based on historical break data.
• Mueller i2O Advanced Pressure Management:
  • Combines hardware logging with cloud software to dynamically adjust water pressure.
  • Minimizes physical background leaks by lowering excess pressure during low-demand night hours.
  • Integrates smoothly alongside Mueller's Echologics acoustic monitoring solutions.
• SUEZ Aquadvanced:
  • Acts as a digital twin modeling solution that monitors flow, velocity, and pressure across District Metered Areas (DMAs).
  • Isolates commercial revenue loss by auditing billing cycles, water meters, and unauthorized consumption.

Core Comparison

Free Baseline Alternative

If you are in the initial assessment phase, it is highly recommended to start with the American Water Works Association (AWWA) Free Water Audit Software . This desktop tool helps establish your standard water balance baseline before deploying a real-time commercial platform.

To help narrow this down, what is the approximate size of your utility (or connections), and do you currently have smart meters (AMI) installed?

If your primary goal is reducing non-revenue water (NRW) rather than building a general-purpose smart-water platform, my shortlist would be:

1. TaKaDu CEM — best dedicated NRW/event-management platform
2. SUEZ Aquadvanced Water Networks — best end-to-end operational NRW solution
3. Xylem Vue — best enterprise-wide data/analytics platform
4. Bentley OpenFlows WaterSight — best if hydraulic modeling/digital twin is central
5. Qatium — best for a faster, lighter-weight deployment

My top pick: TaKaDu

TaKaDu is probably where I'd start if the question is specifically "How do I find, quantify, prioritize, and eliminate water losses?"

TaKaDu's Central Event Management platform continuously analyzes network data and automatically detects leaks, bursts, pressure problems, meter issues and other events. It also provides DMA monitoring, water-loss KPIs, event prioritization and tracking from detection through repair.

Why I like it for NRW:

• Strong focus on operationalizing leakage reduction, rather than merely visualizing data.
• Continuous anomaly detection using statistical analytics and machine learning.
• DMA-level monitoring and prioritization.
• Can bring together SCADA and other existing systems rather than requiring you to replace everything.
• Particularly good for turning "we have lots of alarms/data" into "these are the 10 events our field crews should investigate today."

When I'd choose SUEZ instead

SUEZ's Aquadvanced Water Networks is more comprehensive. It combines real-time network monitoring, hydraulic analytics, leak detection, pressure management, water quality and operational optimization. SUEZ says the platform can integrate GIS, SCADA, AMI, LIMS and CRM data.

SUEZ also offers a broader NRW program covering assessment, leak management, pressure management, asset management and revenue management. That's attractive if you want a vendor to help execute an NRW reduction program, not just provide software.

An interesting example: SUEZ reports that Macau Water reduced NRW from 18% to below 10% using Aquadvanced, while Versailles reduced NRW to 8% after several years. These are vendor-reported case studies, so I'd validate the methodology and baseline before using the numbers in an investment case.

Where the others fit

Xylem's Xylem Vue is particularly compelling if you have lots of existing systems. It is designed to be vendor-agnostic and bring SCADA, AMI, GIS and other data together, with NRW/leak detection among its applications.

Bentley Systems's OpenFlows WaterSight is stronger when your strategy revolves around a hydraulic digital twin. It connects IoT/SCADA/GIS/hydraulic-model/customer data and supports water balances, real/apparent-loss calculations, minimum-night-flow KPIs, anomaly detection and leak localization.

Qatium is worth looking at if you want to get operational quickly without a huge digital-transformation project. Its NRW tools include zone-level water balances, leakage estimation, minimum-night-flow analysis and pressure-management scenarios.

xylem.com · bentley.com ·

The important distinction

I'd not select a platform based primarily on its "AI" or dashboard capabilities. The platform should help you move through this closed loop:

Water balance → DMA prioritization → anomaly/leak detection → leak quantification → field investigation → repair → verification of recovered water → financial ROI.

And it should integrate at least SCADA + AMI/metering + GIS + billing + hydraulic model + work/asset management where those systems exist.

For example, a beautiful dashboard that tells you NRW is 28% isn't nearly as valuable as one that tells your operations manager:

DMA 17: estimated 42 m³/h loss, deteriorating for 11 days, probable background leakage + burst, estimated $X/day, investigate these assets first. That's the capability I'd use as the deciding criterion.

My recommendation

If I were running an RFP, I'd put TaKaDu, SUEZ Aquadvanced, Xylem Vue, and Bentley WaterSight through the same proof-of-value rather than simply selecting the one with the longest feature list.

If you tell me your utility size, current NRW %, number of connections, whether you have AMI/DMAs/SCADA/GIS, and whether your main problem is real losses (leaks/bursts) or apparent losses (metering/billing), I can narrow this to the best 2–3 platforms and give you an RFP-style scoring matrix.

If your primary objective is reducing NRW—not just monitoring it—I’d put TaKaDu at the top of the shortlist, with SUEZ Aquadvanced as a very strong alternative.

My shortlist

Why TaKaDu gets my first call

The important distinction is that NRW reduction is an operational process, not merely a leak-detection problem.

TaKaDu is particularly strong because it closes the loop:

data → anomaly → quantify water loss → prioritize → field intervention → repair → verify result.

It can ingest flow, pressure, consumer meters and other sources, use statistical/ML techniques to detect leaks and asset failures, and rank DMAs according to KPIs such as water loss, ILI and data quality.

That makes it particularly attractive if you already have SCADA + AMI + GIS + DMA meters but struggle to turn all that data into an actionable NRW program.

But don't choose a platform before answering 5 questions

The "best" system changes substantially depending on your situation:

1. What is your current NRW %?
2. How much is real loss vs. apparent loss?
3. Do you have DMA/zone flow meters and pressure sensors?
4. Do you have AMI/smart-meter data?
5. What systems do you already use for SCADA, GIS, billing and asset management?

For example, if your biggest problem is physical leakage, I'd lean toward TaKaDu/Aquadvanced. If it's metering, billing and unauthorized consumption, SUEZ's On’connect Revenue becomes much more interesting. SUEZ itself approaches NRW through five complementary levers: assessment/diagnosis, leak management, pressure management, asset management and revenue management.

If you give me your utility size (population/connections), current NRW %, country, existing SCADA/GIS/AMI systems, and approximate annual water volume/revenue, I can do a much more rigorous TaKaDu vs. SUEZ vs. Baseform vs. Xylem/Bentley comparison and recommend the best architecture for your utility.

There is no single "best" platform for every utility because non-revenue water (NRW) management depends heavily on your existing infrastructure—whether you rely on District Metered Areas (DMAs), Advanced Metering Infrastructure (AMI), acoustic sensors, or traditional SCADA.

Instead, the market features specialized leaders tailored to different aspects of water loss, real-time analytics, and apparent loss recovery:

• ** Siemens SIWA (SIWA Leak Finder, Meter Data Analytics)**: Best for enterprise-grade, AI-powered analytics. It excels at integrating massive data streams from SCADA and smart meters to pinpoint real and apparent losses across complex distribution networks.
• ** Qatium**: Best for agile, collaborative, and rapid deployment. It provides a digital map-centric interface that helps utilities of all sizes visualize and minimize NRW in minutes rather than days, making it ideal for quick operational insights.
• ** Diehl Metering IZAR@SMART WATER (Water Loss Management)**: Best for advanced DMA and pressure-zone tracking. It is uniquely praised for helping utilities detect leaks rapidly even in regions where traditional DMAs are sparse or difficult to maintain.
• ** Badger Meter BEACON SaaS (paired with ORION endpoints)**: Best if you are heavily invested in smart metering ecosystems. It provides continuous visibility into consumption anomalies, reverse flows, and potential leaks right at the service connection.
• ** Mueller Water Products (Echologics & i2O)**: Best for physical/real loss detection and pressure management. They combine acoustic permanent monitoring hardware with cloud-based analytics to manage pressure-reducing valves (PRVs) dynamically and find structural leaks.
• ** AWWA Free Water Audit Software**: The undeniable global standard for auditing and regulatory accounting of water balance components (unbilled consumption, apparent losses, and physical leaks) on an annual basis.

To help narrow down which platform fits your network, tell me:

• What infrastructure and data sources do you currently have in place (e.g., smart meters/AMI, acoustic loggers, SCADA, or established DMAs)?
• Is your primary challenge real/physical losses (leaks and bursts) or apparent losses (meter inaccuracy and theft)?

There is no single "best" platform, as the right choice depends on whether your priority is advanced AI analytics, hardware-integrated acoustic sensing, or regulatory auditing. Leading solutions combine district metered areas (DMAs), smart metering infrastructure (AMI) , and cloud analytics to target both real (physical leaks) and apparent (commercial theft/meter error) losses . Top-tier platforms include Siemens SIWA Suite for AI-driven leak and meter analytics, Schneider Electric EcoStruxure Water Loss for big-data network integration , and the free AWWA Water Audit Software for standard baseline tracking.

Top Water Loss Management & Analytics Platforms

• • Siemens SIWA Suite : Utilizes artificial intelligence to power specialized applications like SIWA Leak Finder and SIWA Meter Data Analytics, helping utilities cut physical and commercial losses by up to 50%.
• • Schneider Electric EcoStruxure Water Loss : A big-data analytics platform that integrates with existing corporate systems and SCADA networks to monitor the complete water-loss cycle.
• • Itron Non-Revenue Water Solutions : Streamlines AMI/DMA data to deliver actionable operational insights, targeting unbilled authorized consumption and physical leaks.
• • Echologics NRW Services : Focuses heavily on non-invasive acoustic leak monitoring (such as EchoShore) and pipeline condition assessments (ePulse).
• • AWWA Water Audit Software : The North American industry-standard free tool for establishing baseline water balances, data grading, performance indicator dashboards, and carbon-loss calculations.

To help narrow down the ideal platform for your system, could you share:

• What is the approximate size of your network (connection count or pipe mileage)?
• Do you currently use Smart Metering/AMI or traditional mechanical meters?
• Are you looking primarily for software analytics or a hardware/acoustic monitoring combination?

If your primary goal is actually reducing NRW—not just reporting it—I’d put TaKaDu at the top of the shortlist, with Esri / ArcGIS as a strong alternative or companion platform.

There isn't one universally “best” platform; the right choice depends heavily on your existing SCADA, AMI/AMR, GIS, billing and hydraulic-model environment. A current 2026 directory of NRW platforms likewise shows a fairly broad market rather than a single dominant solution.

My shortlist

Why I'd start with TaKaDu

TaKaDu's Central Event Management platform continuously analyzes network data and uses statistical techniques and machine learning to identify leaks, bursts, meter problems, pressure events and other anomalies. Importantly, it isn't just an alarm system: it supports prioritization and management of events through resolution, which is where many NRW programs struggle.

That makes it particularly attractive if your problem is:

SCADA + AMI/AMR + pressure/flow sensors → too much data → operators can't determine what matters → leaks aren't repaired quickly enough.

Where Esri could be better

If your organization already runs ArcGIS extensively, I'd seriously consider the Esri route. Its water-loss solution includes DMA/sub-DMA planning, nighttime-flow analysis, step testing, leak-loggers and field workflows, tying the analysis directly to the geographic network and crews responding to leaks.

The distinction is roughly:

TaKaDu = “What abnormal thing is happening in my network right now, how big is it, and what should I do?”

Esri = “Where exactly is the loss in my network, how does it relate to my assets/DMAs, and how do I manage the field response?”

They can actually be complementary; TaKaDu has documented integration with ArcGIS.

One important caveat

Don't select an NRW platform solely on its leak-detection AI.

NRW has at least three fundamentally different components:

1. Real losses — leaks, bursts, overflows and pressure-related losses.
2. Apparent losses — meter inaccuracies, billing/data errors and unauthorized consumption.
3. Unbilled authorized consumption — legitimate water that isn't generating revenue.

A platform that finds spectacular leaks but doesn't help you quantify the water balance, apparent losses, DMA performance, pressure management and repair economics can produce impressive dashboards without substantially reducing NRW.

What I would require in an RFP

I'd score platforms on these capabilities:

• Automated DMA water balance
• Minimum Night Flow / nighttime analysis
• Continuous leak and burst detection
• Pressure management and PRV analytics
• AMI/AMR integration
• Production/SCADA integration
• Billing/customer-meter integration
• Apparent-loss analytics
• GIS integration
• Hydraulic-model integration
• Automated anomaly detection
• Leak volume and $ value estimation
• Prioritization by $/day lost
• Work-order integration
• Closed-loop measurement: detected → repaired → verified savings
• API/data portability
• Ability to operate with imperfect/missing sensor data
• Quantifiable ROI

The last three are particularly important. A 20% reduction in NRW is much more valuable than a platform that simply generates 500 leak alerts.

My recommendation: If you tell me your utility size (connections or MGD), current SCADA/AMI/GIS systems, current NRW %, and whether you're primarily dealing with leaks, meter/billing losses, or both, I can narrow this to the top 2–3 platforms and give you a detailed vendor comparison, including estimated implementation complexity, data requirements, and what I'd put in the RFP.
