• Expansion project will double capacity of existing wastewater plant
  • 25 groups submitted prequalification entries in early 2014
  • Bahrain’s Works Ministry is undertaking a major programme to expand and upgrade the country’s wastewater network

Bahrain’s Works Ministry has prequalified 10 groups for the engineering, procurement and construction (EPC) contract for the Tubli sewage treatment plant (STP) expansion.

The ministry received prequalification documents from 25 groups in January 2014, and, according to sources close to the project, has qualified 10 to participate in the tender. The client is preparing to issue request for proposals (RFPs) during or shortly after Ramadan (approximately 17 June-17 July).

The prequalified groups are:

The scheme is being funded by the governments of Kuwait and Saudi Arabia, so prequalification was restricted to:

  •     Kuwaiti contractors
  •     Kuwaiti / Bahraini joint ventures
  •     Kuwaiti / foreign joint ventures or consortiums
  •     Saudi contractors
  •     Saudi / Bahraini joint ventures
  •     Saudi / foreign joint ventures or consortiums

The expansion will double the capacity of the plant from 200,000 cubic metres a day (cm/d) to 400,000 cm/d. Tubli is currently dealing withmore than 300,000 cm/d of wastewater, leading to raw sewage discharges into the sea.

Tenders for consultancy contracts on pipelines and use of treated sewage effluent related to the plant were issued in January 2015.

The project is part of Bahrain’s efforts to expand and upgrade its wastewater treatment plants and networks, which are currently operating at over capacity.

The Works Ministry is also planning to build a new sewage treatment plant, Al-Madina al-Shamaliya  and long sea outfall project. The ministry received prequalification entries from 17 companies in June 2014.

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.

Technical bids for two packages in Al-Medina al-Shamaliya are under evaluation, in coordination with donors the Abu Dhabi Fund for Development.

The first package consists of a 40,000 cm/d STP, pumping stations, a tank and an emergency outflow system.

The second package involves implementing 15.6 kilometres of sewerage lines.
