Abstract

Why is Non-Revenue Water (NRW) assessment so important for any water utility? It is common knowledge that the NRW in any water utility is a percentage of the water volume pumped into the network - but this simple percentage figure just isn’t sufficient to understand the water utility’ problem and elaborate an appropriate reduction strategy. Therefore it was necessary to apply the nowadays available methods and tools which had helped to establish a first baseline. The following pages provide a brief overview on the methodology and the related terminology.
