The Doha South Sewage Infrastructure Project implemented by the Public Works Authority ‘Ashghal’ has been awarded the Oracle’s “Construction and Engineering Excellence Award” for “Enterprise-wide Standardization in Public Infrastructure”.

The project was recognised for theuse of digital engineering as a primary strategy for process efficiency, resource utilization, record management, enhanced collaboration, and implementation of construction best practices. The award was received by Eng. Khalid Maher Al-Qatami, Head of Treatment Plants and TSE Network Projects Section at Ashghal, during Oracle’s annual awards ceremony held on 26 February 2020 in Doha. The ceremony was also attended by representatives from M/s. Jacobs (previously CH2M), the Project Management Consultant for this project.

It is worth noting that Oracle is an international organisation that is specialised in providing technological solutions to clients from different countries including USA, Europe and Asia.

Ashghal’s Doha South Sewage [].jpgProject Progress

In April 2019, Ashghal completed the construction works of the Main Trunk Sewer (MTS) as part of the Doha South Sewage Infrastructure Project. The MTS is 16-kilometre long and is divided into three segments, Eastern, Northern and Western. In addition, construction of sevenlateral sewer tunnels ofapproximately 24 kilometres was completed using 170 shafts at different locations within Doha South. The flows from these lateral sewers will be conveyed to the three segments of the MTS, which will then convey these flows to the existing Doha South Sewage Treatment Plant through a 40 metres deep foul sewerage pumping station.

An important feature of the project is that the gravity MTS will reduce the environmental impacts by fully controlling the odours at the sewage treatment works and conveying system, and reduce other environmental problems arising from sewage overflow due to excess hydraulic pressure on the existing drainage network, where sewage flows exceed its absorptive capacity. The project is designed to accommodate the population growth expected in Doha South, and has the capacity to be linked to future infrastructure projects. Once complete, the project will enable the decommissioning of more than twenty foul sewer pumping stations located in the residential and commercial areas in the south of Doha.

Several International Awards

It is worth mentioning that the Doha South Sewage Infrastructure Project achieved several prestigious international awards during 2019. The project won the Engineering News Record (ENR)’s Global Best Project Award in the Wastewater Category, in recognition of its design innovation, outstanding health and safety performance, effective risk management, and implementation of construction best practices. The project also successfully achieved the Civil Engineering Environmental Quality Assessment and Award Scheme (CEEQUAL)’s “Design and Building Award” with ‘Good Rating’, as well as the “Exceptional Achievement Award” in the Water Environment and Resources Category, making it the first and only project to obtain these awards in the Middle East at the time.

For the second year in a row, the project also wonin 2019 the Gold Award from the Royal Society for the Prevention of Accidents (RoSPA), for its outstanding occupational health and safety performance, in addition to adopting the best risk management practices in all aspects of the project implementation.
