Bahrain upgrades wastewater treatment capacity
- Capacity of plant will be doubled to reach 400,000 cm/d
- Prequalification entries were submitted in January 2014
- Scheme is being funded by Kuwaiti and Saudi Arabian governments
Bahrains Works Ministry is in the final stages of preparing an engineering, procurement and construction (EPC) tender for Tubli sewage treatment plant (STP) expansion, and expects to issue it in March.
The ministry received prequalification documents from contractors in January 2014, and a tender was originally planned for mid-2014.
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 with more 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.
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.
