Qatar’s Public Works Authority (Ashghal) has invited contractors to prequalify for the contract to design and build the proposed Integrated Industrial Wastewater Treatment Works.

Contractors have until 8 October to submit prequalification entries for the contract, which will include design, build, operation and maintaining of the industrial wastewater scheme.

The wastewater project will be built about 2km southwest of the Doha Industrial Area, adjacent to the existing Industrial Area Sewerage Treatment Works. The first phase of the project is planned to provide a treatment capacity of 10,000 cubic metres a day (cm/d), and is scheduled to be completed before the end of 2016.

After completion of the first phase, the plant will provide integrated facilities to treat industrial wastewaters coming from light to medium categories of industrial and trade factories located in Qatar, and dispose the treated sewage effluent produced by the existing Industrial Area Sewerage Treatment Works.

The new facility will be equipped to handle wastewater with pollutant levels exceeding municipal discharge limits that control effluent disposal to the public sewer network.

The industrial wastewater plant will be faced on a fully integrated design, which will have multi-stream treatment processes. The process will allow further expansions in the future.

The project is the latest of a number of major schemes that Qatar is undertaking to improve its wastewater infrastructure. In May, MEED reported that Ashghal had set aside a budget of QR30bn ($8.2bn) for wastewater projects in the run up to hosting the World Cup in 2022.
