AECOM wins Muscat 'flat-sheet' bioreactor design
Firm signs $1.5m Haya Water contract for wastewater treatment plant
AECOM has won a $1.5m contract from Haya Water, the trading name of Oman Wastewater Services, to design phase two of Al Ansab Sewage Treatment Plant (STP) and Azaiba Central Pump Station in Muscat, under the supervision of the Ministry of Environment and Climate Affairs.
The Al Ansab upgrade is part of Haya Water’s Water Reuse Project to implement a 290km network for the transportation and distribution of treated water. The design for the project will use a flat-sheet membrane bioreactor and be capable of treating up to 110,000m3 each day.
AECOM, which designed the original Al Ansab STP in 2002, is expected to nine months to complete the new project and will involve teams from Oman, the United States and the United Arab Emirates.
Oman now produces about 80,000m3 of treated wastewater each day, but this is expected to increase to 220,000m3 each day with the completion of the Haya’s Water Reuse Project by 2018. It is expected that 80% of Muscat residents will be connected to the sewage networks by that time.
Additionally all of Haya Water’s wastewater treatment plants are now expected to employ MBR technology moving forward, and about 50,000m3 each day of treated wastewater has been earmarked for irrigation by the Municipality to irrigate public parks and trees on Sultan Qaboos Road.
