This rehabilitation and upgrading project involved UPVC/high-density polyethylene sewer pipeline of 200 mm to 500 mm dia., ductile iron force mains of 150 to 500 mm dia., three sewage pump stations and five sewage lift stations, a sewage treatment plant of 5,600 cu. m/day capacity based on extended aeration process. Submerged membrane filtration system was used for the first time in this sewage treatment plant in the Sultanate of Oman.
The purpose of this project was to upgrade and rehabilitate the existing Sewage Treatment Plant (STP) and design of Sewage Collection System at Al-Buraimi. The 3000 cu. m/day capacity STP based on extended aeration process was meant to treat the sewage carried through the collection system comprising 4 km main and 25 km lateral sewers, one lift station and 8 km pumping main.
The objective of this project was the upgrading and rehabilitation of the existing Sewage Treatment Plant (STP) and design of the Sewage Collection System. The 1400 cu. m/day capacity STP is based on extended aeration process and will treat the sewage carried through the collection system comprising 3 km main and 26 km lateral sewers, 2 lift stations and 3 km pumping main.
