The New Darsait Sewage Treatment Plant is a major new part of the Muscat wastewater master plan. Since 2012, KEO has been providing key services for the design, construction and two year operation of the second largest Membrane Biological Reactor (MBR) in the GCC which will have a design flow of 50,000 m3 per day. KEO is acting as the overall Project Manager to manage the design and construction activities on all aspects associated with the contract.
The new plant provides the necessary advanced wastewater treatment capacity to accommodate projected increased flows which will arrive at the sewage treatment plant when the concurrently constructed sewerage network projects are commissioned. The main treatment elements of the sewage treatment plant will be contained in three separate buildings designated as the Inlet Treatment Building, the Biological Treatment Building and the Treated Sewage Effluent Building.
