Design a storm water drainage system for the area shown in the following figure. Draw a (1:50) profile along the route of MH-1, MH-2 and MH-3. On the profile show all pipe sizes, slopes, and ground and invert elevations. The rainfall intensity (mm/h) for the area can be found from the following equation: i=1100/(t+45); where t is the rainfall duration (minute) The minimum allowable scouring velocity required to avoid the deposition of solids is 1.2 m/s and the maximum is 5 m/s. The minimum slope is 1% for pipes ≤ 760 mm and 0.5 % for diameter > 760 mm. The minimum depth of the sewer below ground must be 30 cm and 75 cm for pipes under roadways and coefficient of roughness, n = 0.013 is applicable.
