The Problem: Non Revenue Water

Non Revenue Water (NRW) is the difference between the volume of water put into a distribution system and the volume billed to consumers. High levels of NRW, through leaks, illegal or unmetered connections and inaccurate billing, drain utility revenue and drive up operating costs.
