About Company


Oman Water and Wastewater Services Company S.A.O.C. (the "Company") is a closed joint-stock company, registered under the laws of the Sultanate of Oman. The Company was established on 21 June 2003, as “Oman Wastewater Services Company S.A.O.C”, and was granted concession rights by the Government of Oman through Royal Decree No. 69/2005 on 13 July 2005. Under this decree, the Company became responsible for the operation and management of the wastewater sector in the Governorate of Muscat.

In 2014, the Government expanded the Company’s mandate to include the operation and management of the wastewater sector across the entire Sultanate, except for the Dhofar Governorate.

On 9 December 2020, Royal Decree No. 131/2020 restructured the water and wastewater sector. As a result, all assets, records, rights, and obligations of the former Public Authority for Water were transferred to the Company. The decree also designated the Company as the sole entity responsible for water distribution and wastewater services across all governorates of Oman, except Dhofar, leading to the dissolution of the Public Authority for Water.

In May 2021, the Company was renamed as Oman Water and Wastewater Services Company S.A.O.C., operating currently under the trade name “Nama Water Services”.

On 8 October 2023, following the issuance of Royal Decree No. 40/2023 regulating the water and wastewater sector, the Company was officially granted a license by the Authority for Public Services Regulation (APSR).

Nama Water Services is a subsidiary of Electricity Holding Company S.A.O.C. (Nama Group).
