In June 2026 Nama Water Services awarded a 15-year performance-based contract to run water and wastewater operations in Muscat and North and South Al Sharqiyah, a cluster serving 2.3 million inhabitants, about 43% of Oman's population.
Two values for one contract
SUEZ put the contract at €2 billion in its release of 29 June 2026. The Oman Observer reported about OMR 900 million on 4 July 2026. SUEZ names National Trading Company and National Energy Center as its partners; the Observer also lists the Oman Infrastructure Fund.
What the operator takes over
The scope covers 240 wells, 10,700 km of pipelines delivering 470,000 m³ a day and more than 400,000 smart meters. On the wastewater side it includes 22 treatment plants with 280,000 m³ a day of capacity, about 3,000 km of sewers and 400 km of treated effluent networks. Performance is measured against 33 key performance indicators, and Nama Water Services keeps oversight of governance, regulation and performance management.
The loss target
The contract aims to cut water losses in the cluster from 34% to 11% by 2040. Nationally, Nama Water Services reported losses of 41.82% in 2021 and 37.10% in 2024, when its target was 35.00%. Its 2025 annual report gives a further 4% reduction on 2024. In 2024 the company produced 445.57 million m³ of potable water and delivered 280.28 million m³.
