Question- The average flow rate of a wastewater treatment plant is 20 MGD and the peak factor is 2.0. Design the sedimentation tanks by using the following information:

1) Hydraulic retention time = 90 minutes (based on peak flow)

2) Hydraulic loading rate = 800 gpd/ft2 (based on peak flow)

3) Weir loading rate = 18,000 gpd/ft

4) Number of tanks = 10 (in parallel)

5) Length : width = 7:1
