A primary settling tank is to be designed for a municipal wastewater treatment facility. The average design flow is 2 MGD (peaking factor 2.1). EPA regulations require that the overflow rate be 800-1200 gpd/ft2 for average daily flow and 2000-3000 gpd/ft2 for peak flows. The detention time required at average flow is 2 hours.

a. Determine the diameter of the settling tank.

b. Determine the design depth.
