The level of non-revenue water was estimated at about 48% in 2010. It was estimated to be highest in the South (52%) and lowests in Beirut-Mount Lebanon (40%). This is high by international standards, but similar to the levels in Syria, Jordan and Turkey. Since there is little metering, it is difficult to estimate the level of non-revenue water. The share of metered connections was estimated at 16% in the Beirut-Mount Lebanon governorates in 2010, and was lower in other governorates. Most industrial and commercial water users were metered, while few residential users are metered.
