Nonrevenue water (NRW) reduction indicators need to be versified. Expressing the NRW levels in liters lost per connection per day, demonstrates a large variation in results. The best performing systems in terms of NRW ratios--NRW reduction targets are defined as the ratio of unbilled production versus total input capacity in m3/day--are not necessarily the lowest in absolute terms. To get a fundamental idea on actual performance, NRW results should at least be reported in ratios and absolute terms.
