The Arana treatment plant gets preferred bidder: A consortium comprising Power and WaterUtility Company for Jubail andYanbu (Marafiq), Miahona, and Buhur for Investment was named the preferred bidder for the Arana Independent Sewage Treatment Plant in Makkah, according to Tadawul disclosures. The estimated contract value — excluding any future expansion — comes in at more than SAR 3 bn.
Who’s got what? The 25-year build, own, operate, transfer contract places Marafiq as a technical member with a 35% stake and Miahona as a lead consortium member with a 35% stake, with Buhur having a 30% share.
Scope: The project covers the full development cycle of a new 250k cbm/d sewage treatment plant — design, financing, EPC, commissioning, operation, and ultimate transfer at the end of the agreement. The contract provides the option to scale up capacity to 500k cbm/d at the SWPC’s request.
It’s been in the works for a while: The Saudi Water Partnership Company (SWPC) was expected to award the Arana project in Makkah by 4Q 2025. The project is scheduled for completion in 4Q 2028. The consortium will now move forward toward commercial and financial close, with further updates expected once agreements are finalized.
