An existing rectangular clarifier at a drinking water treatment plant is 18 ft wide and 72 ft long. It was originally designed for an overflow rate of 600 gpd/ft2 and it is currently operating at its design capacity. Inclined-tube settling bundles are to be added and will occupy 80 percent of the plan area, inlet flow distribution systems for the retrofitted tube bundles excludes flow through the remaining 20 percent of the surface area. Tube bundles will have a design overflow rate of 5,000 gpd/ft2 . Complete an analysis to determine the present capacity in gal/day, and the increased capacity in gal/day after the tube bundles are installed.

Drainage of Pavements

Pavement Drainage holds ample significance, as it prevents the accumulation of water or any liquid on the surface of pavements and ensures proper drainage system. With proper design and gradual slopes provided, the water gets easily removed from the surface into the drains, which are essential during heavy rains and unusual weather conditions keeping it less prone to accidents and increasing the durability of the pavement structure.
