64. The design of drainage system applied as follows:  Every stacks contains many fixture are groups and there are many no. of stacks in each floor.  The vent design of the stack pipes equal 4 in until reach the last floor it becomes equal 4 in, so that to obtain a good ventilation to drainage system in the building.  Many manholes were used for collecting the all drainage water

65. The design of drainage system applied as follows  Every 100m 2 needs a floor drain in the roofs to collect rain water.  A septic tank was designed ( 2*3*2) to collect waste water in second basement.   A two submerged pumps (WILO TS 50 H 111/11) was selected with 10m3/h flow and 10m head.
