The Saudi subsidiary of Egyptian firm Hassan Allam Holding has won the civil works contract for the Buraydah 2 independent sewage treatment plant (ISTP) project in Saudi Arabia.

The 150,000 cubic-metre-a-day sewage treatment facility is being implemented by a team of Spain's Acciona Agua and local firms International Water Distribution Company (Tawzea) and Tamasuk.

Buraydah 2 is one of three schemes comprising the second batch of the kingdom’s ISTP programme.

It will be developed at a cost of SR845m ($225m).

Saudi Water Partnerships Company (SWPC) and the project developer team achieved financial close on the three projects in March, as MEED reported.

Saudi Arabia’s Environment, Water & Agriculture Ministry and SWPC signed the project agreements in September with the developer consortium.

The first contract covers the development of the Medina 3 ISTP project, the largest of the three schemes with a design capacity of 200,000 cm/d. The project's total cost is SR960m ($256m). 

The Acciona-led team offered a levelised water cost of SR1.2157 ($0.32) a cubic metre (cm) for the contract.

The second contract entails the development of the Buraydah 2 and Tabuk 2 ISTP schemes. Tabuk 2, which has a capacity of 90,000 cm/d, will cost SR550m.

The team submitted a levelised water cost of SR1.4395 ($0.38) a cubic metre for both schemes.

A team of Acciona, Tawzea and Mutlaq al-Ghuwairi has been confirmed as the engineering, procurement and construction (EPC) contractor for the three schemes.

In May 2019, the client appointed Sumitomo Mitsui Banking Corporation (SMBC) as financial and lead adviser, and UK firms DLA Piper and Atkins as legal and technical advisers, respectively, for the second batch of ISTPs.
