Storm Sewers and Detention

The storm drains system transports rainwater or stormwater and other runoff from roads, parking lots, and roof downpipes directly to nearby creeks, rivers, or the sea without any treatment.

There are two main types of water distribution system layouts. In the Answer system, the main line is connected back to itself and the smaller lines join the main line at two or more locations. In the Answer system, a main distribution pipe is used, and smaller lines are connected to the main line at only one point along the length of the main line. The Answer is preferred over the Answer because it has isolation valves and water flows in more than one direction, which can avoid having to shut off water to all customers in an area during repairs. series looped branched system looped system parallel branched

As a field engineer you are tasked to estimate the 25-year peak discharge for concrete parking lot that is 310 feet wide by 600 feet long using Rational formula. The longest flow path is 310 feet of sheet flow across the lot on a slope of 0.005 and 600 feet of shallow concentrated flow along the parking lot's length in a paved channel on a slope of 0.015. Use SCS procedures to determine the time of concentration using a 2-year, 24-hr rainfall of 2.4 inches. Use Figure below for the rainfall intensity in the rational equation.
