A trunk sewer is to be designed to drain a 300 ha tract of urban land of mixed land use. The average sanitary sewage flow is estimated to be 120, 000 L/ha/day, the maximum flow peak factor is estimated to 2.5 and minimum flow peak factor is estimated to be 0.50. The ground surface profile along the trunk sewer route is 0.5%. The circular pipe is concrete with a manning n=0.013. (a) Propose an appropriate diameter for the trunk sewer. (b) Determine the flow rate and velocity of the pipe running full. (c) Determine the depths and velocities of flow at the average, maximum and minimum flow conditions.
