Important Methodological Distinction: The 324 billion m³/year (85.6 trillion US gal/yr) freshwater loss reported by the World Bank (Continental Drying, Nov 2025) measures satellite-observed hydrological depletion across continents (68% groundwater, 18% surface water, 9% soil moisture, 5% snow) and not municipal Non-Revenue Water (126 billion m³/year).

1. Global Balance Across 12 World Regions

Compare all 12 world regions modeled by Liemberger & Wyatt (2018/2019). Toggle the metric buttons to switch between annual volume, per-capita intensity, financial damage, and daily losses.

Annual NRW Volume by World Region (Billion m³/yr)

Key Takeaway: Latin America & Caribbean (25.2B m³; 20.0%) and South Asia (23.2B m³; 18.4%) account for 38.4% of all global water losses.

Volume vs. Per-Capita Efficiency

Bubble size = Financial loss (Billion USD/yr)

Pattern: East Asia ranks 3rd in total volume (19.3B m³) but operates more efficiently per capita (42 L/cap/day) than Europe (50 L/cap/day). Australia & New Zealand lead globally at 36 L/cap/day.

2. Continental Deep Dive: Countries, Utilities & Cities

Select a continent to examine verified national, municipal, and utility-level datasets—including EurEau 2026 in Europe, ESAWAS benchmarking in Africa, and PWWA utility reports in Oceania.

Physical Real Losses in Europe (EurEau 2026, 2022–2024)

Leakage as % of system input across 24 ranked countries (EU27 avg: 22.9% real losses; 28.59% total NRW)
EU27 Median: 19.0%

Luxembourg note: Printed as 0.0% in EurEau 2026 leakage ranking (no separate real-loss figure), with 10.0% total NRW confirmed. Missing EU reporters: Croatia, Finland, Greece, Latvia, Portugal, and Slovakia.

Length-based NRW Index (EurEau 2025): Italy: 6,534 m³/km/yr · Bulgaria: 6,233 m³/km/yr.

Western Balkans, Turkey & Eastern Europe (World Bank ECA 2025):

Across Albania, Bosnia & Herzegovina, Kosovo, Montenegro, North Macedonia, Serbia, and Turkey, the World Bank documents widespread distribution losses of 30–60% NRW driven by excess pressure and aging pipes.

Regional baselines: Russia/Ukraine/Belarus: 3.5B m³/yr (65 L/cap/day) · Caucasus & Central Asia: 2.9B m³/yr (152 L/cap/day).

3. Global Explorer: Countries, Cities, Utilities & Data Gaps

Because no single global registry publishes standardized national NRW percentages for every country, this explorer transparently pairs all verified measurements with documented national data gaps and their corresponding regional benchmarks.

IWA Water Balance & Utility Benchmarks

1. Physical Losses (Real Losses)

Water physically escaping through pipe bursts, leaking joints, cracks, and reservoir overflows (EU27 average: 22.9%).

2. Commercial Losses & Unbilled Consumption

Meter under-registration, unauthorized connections, billing errors, plus firefighting and mains flushing (lifts EU27 average to 28.59% total NRW).
