Drainage System in Building There are many type of fixture that used in the building and there sizes of every pipe in the fixture are mentioned, they are establishing from the international standard code.

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
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.
