  2. Unaccounted-for water (UFW) is the difference between "net production" and "consumption" (the volume of water that can be accounted for by legitimate consumption, whether metered or not) • Water loss levels (UFW) vary widely per country and within one country per city it's ranging from 6% to 63% • AWWA Leak detection and Accountability Committee (1996) recommended 10% as a benchmark for UFW as the following: • < 10% Acceptable. • 10-25%, intermediate, could be reduced • > 25% matter of concern, reduction needed
