The consortium led by South Korea’s Samsung Engineering has completed construction of the Muharraq sewage treatment plant (STP) in Bahrain.

The Works Ministry held a ceremony to mark the completion of the project on 25 June, which was attended by Bahrain’s prime minister, Khalifa bin Salman al-Khalifa.

The Works Ministry awarded a consortium of South Korea’s Samsung Engineering Company, Abu Dhabi financial services firm Invest AD and the UK’s United Utilities International the contract to build the Muharraq plant in February 2011 under a build-own-operate-transfer (BOOT) contract, the first BOOT project in Bahrain.

The project has been debt financed by the Export-Import Bank of Korea (Kexim), Japanese lender Sumitomo Mitsui and French banks Natixis and Credit Agricole. The banks joined the deal towards the end of 2010 and will together provide about $300m

The plant will process 100,000 cubic metres a day (cm/d). Samsung Engineering and United Utilities will handle operations and maintenance for 27 years after completion.

Bahrain is pushing ahead with two other STP projects in 2014 to boost the kingdom’s sewage treatment capacity.

In the first quarter of this year, the Works Ministry received prequalification entries from 17 firms for the contract to build the Al-Madina al-Shamaliya sewage treatment plant (STP) and long sea outfall project.

The first phase of the STP will have a capacity of 40,000 cm/d and is scheduled to be completed by 2017. The STP and associated works is also being funded by the Abu Dhabi Fund for Development.

The other project is the expansion of the existing Tubli STP, which will double the capacity of the facility from the existing 200,000 cm/d to 400,000 cm/d. The Tubli expansion is scheduled to be carried out between 2015 and 2018. The ministry received prequalification entries from 25 groups in December 2013. The project is being funded by the governments of Kuwait and Saudi Arabia.
