Drainage is a very important building, especially in big cities that have many buildings. For some countries, drainage has an important role to prevent them from flooding. In addition, the drainage keeps the soil from sudden movement so that it breaks down the building. But in some other countries still, have problems with drainage. Usually, drainage quickly damaged, so easily lead to flood disasters. Damage to the drainage must be promptly repaired so as not to cause any other damage.

Building drainage should be accompanied by careful planning in order to survive long. Here are the things to consider when planning a drainage development:
Rainfall data is required to be projected until the planned year. Rainfall usually has an annual anniversary like 5 years, 10 years, and so on. To avoid periodic flooding, time series rainfall data is required in previous years.
Drainage was built following the road. So sometimes there is an area where the drainage water cannot be drained due to its lower place, so when there are heavy rains, then the rain is only accommodated in the drainage (not flowing) so that if it exceeds its capacity it will occur flood.
– Knowing the land
The required land use is like how wide of residential, industrial, forest, rice field, green open space. It is intended to know how much rainwater is absorbed into the soil, and rainwater that is not absorbed into the soil (usually on a pavement area such as a highway), so it must be drained into the drainage.
– Drainage capacity
After considering the above factors, it is time to calculate the capacity and dimensions of drainage channels. The drainage channel should be able to accommodate domestic, non-domestic, and rain wastewater.
