Decision scope
Questions answered
Where does Muscat's water come from?
From Ghubrah II (191,000 m³ a day) and Qurayyat (200,000 m³ a day) desalination plants, about 40,000 m³ a day from two NWS-operated plants, and transfers from the Barka Zone of about 242,000 m³ a day available capacity.
Who runs water in Muscat?
Nama Water Services distributes water and runs wastewater, Nama PWP buys bulk desalinated water and APSR regulates; a SUEZ-led consortium was awarded a 15-year operations contract valued at about RO 900 million by NWS and €2 billion by SUEZ.
What do households pay?
NWS lists OMR 0.66 for citizen households with two accounts or fewer and OMR 0.770 for non-citizen households, plus a monthly sewage fee of OMR 2.100; the page does not state the unit.
Which new supply is coming?
Ghubrah III (300,000 m³ a day), expected to operate from Q2 2027, and the Wadi Dayqah dam plant (35,000 m³ a day potable), 57% complete in October 2026 and due in May 2027 (Nama PWP plans for 2028).
How exposed is Muscat to floods?
Nearly 45% of the capital's areas were reported vulnerable to wadi floods and about 20% to coastal floods; the Wadi Adai dam in Mutrah was 53.7% complete in June 2026.
