Globally, non-revenue water amounts to an average of 34 percent of processed water. In other words, 34 percent of the water that a utility has treated and pumped is not billed. The World Bank estimates that non-revenue water costs utilities $14 billion, annually, worldwide. In the United States, reports have shown that the non-revenue water totals between 10 and 30 percent, with more than 240,000 main breaks each year.
