A drinking water treatment plant is designed with three sedimentation basins in parallel. Each basin is designed with an overflow rate of 1,200 gpd/ft2 (gallons per day per square foot). (“In parallel” means that the flow is split evenly between the basins as shown below.) A. If the plant flow is 20 mgd (million gallons per day), find the plan area of each basin in square feet. B. Calculate the dimensions of the basins (length and width in feet) if...
