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 CF3-2 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, the largest of its kind in South Africa, and state-of-the-art construction methods, including microtunnelling and silent sheet piling.
