AG Bulk Gravity Pipeline
Treated water for this bulk pipeline will be obtained from the Maphumulo Water Treatment Works. The bulk pipeline will link the water treatment works to Reservoir AG and is designed for 9 offtake points. The bulk is some 15 800m long and is made up of uPVC and Klambon GMS pipe. The uPVC portion is 355mm dia and has three classes, namely Cl 9 (1280m) Cl 12 (1350m)and Cl 16 (510m). The Klambon pipe is all Class 25 and has the following diameters, 300 (7450m), 250 (4250m), 200 (1000m) and 150 (100m). Associated air (65no), scour (40no) and isolating valves and chambers are constructed along the route as detailed in the final design drawings. Two bridge crossings and four ravine pipe bridge structures are also included in the pipeline route, with much of this route located on steep terrain.
