Nama Water Services (NWS), part of the Nama Group, has opened a public-private partnership (PPP) tender inviting local, regional, and international consortia to apply for the Request for Qualification (RFQ) for two sewage treatment plant (STP) projects. 

The two projects include the development and long-term operation of the Al Ansab STP (Phase III) and the Al Amerat STP (Phase II). The scope covers capacity expansion as well as the long-term operation and maintenance of both new facilities and existing assets. The Al Ansab STP is planned for an expansion of approximately 82,000 cubic metres per day, increasing its total capacity from 125,000 to about 207,000 cubic metres per day.  The Al Amerat STP will see an expansion of about 36,000 cubic metres per day, raising its capacity from 18,000 to 54,000 cubic metres per day. Together, the projects represent a significant increase in wastewater treatment capacity to support demand across Oman. 

The Project will be procured under a Build-Own-Operate-Transfer (BOOT) model, covering design, financing, construction, operation, and maintenance of new facilities alongside the long-term operation of existing assets. Interested parties may register to receive the RFQ by emailing the company name, contact person, position, and phone number to ppp.tendersgowwsc.nama.om. Instructions to access the RFQ and subsequent updates will be provided upon registration. Applications must be submitted by December 16, 2025, at 2:30 pm Gulf Standard Time (GST).
