Diyar Al Muharraq - Pump Station
As part of the sewer network upgrade in the Kingdom of Bahrain, a 23m deep pumping station was constructed on the man-made reclaimed island of Diyar Al Muharraq. To enable the construction of this pump station a 23m diameter shaft was constructed using 900mm interlocking male and female secant piles.
ByrneLooby undertook a detailed design review and value engineering exercise for the deep shaft. This included an independent check on the process design and the structural design, a geotechnical assessment of the proposed solution along with the overall final configuration and suitability. Advice on the dewatering strategy in this aggressive marine environment was also provided, including consideration of pile overlap, drilling methodology and the degree of water cut-off that could be achieved.
