Determine the total sanitary sewer loading for the three pipes in the subdivision shown below. Also determine the invert elevations based on the design criteria listed. What is the total peak flow into the lift station (MH - 4) in L/s? What are the full flow velocity and full flow discharge for each pipe. What is the ratio of flow depth to pipe diameter for each pipe (i.e. d/D)? Street crown elevations are shown in parentheses.
