The Cape Flats 3 Bulk Sewer – Phase 2 (CF3-2) provides the final link in the City of Cape Town’s strategic Cape Flats bulk sewerage system. The project took the most prestigious spot at the 2018 CESA Aon Engineering Excellence Awards, as the winner for projects with a value greater than R250 million. The CF3-2, designed by AECOM and constructed by CSV Construction, is a 1 000 mm diameter ductile-iron rising main with a design capacity of 1.3 m3/s. This project stands out because of its innovative design aspects, such as the inclusion of a barometric loop with vortex drop structure, and state-of-the-art construction methods, including microtunnelling.
