A water treatment plant has an average influent flow rate of 15 MGD and peak flow rate of 25 MGD with primary clarifiers. The primary clarifiers are designed for an overflow rate of 1,000 gpd/ft2 for average flow conditions and 2,000 gpd/ft2 for peak flow conditions. The minimum hydraulic residence time is 2 hours. Design two rectangular clarifiers with a length to width ratio of 3:1. 1) The length of each clarifier in feet is most nearly: 2) The volume required in each clarifier in cubic feet is most nearly:
