An estimated 78.6 million cubic metres of potable water, representing 21.6 per cent of the total output of desalinated and groundwater handled by Oman’s Public Authority for Water (Diam), remained unaccounted for in 2018.

Unaccounted for Water (UFW) —typically attributed to leaks in underground pipeline systems, metering errors and unbilled metres — represents a significant share of Diam’s revenues and is the subject of intensive mitigation efforts.

Those efforts helped bring down water losses linked to UFW from 24.3 per cent (equivalent to 98.3 million cubic metres) in 2017 to 21.6 per cent last year, according to Diam’s Executive Chairman, Mohammed bin Abdullah al Mahrouqi.
