Manangement of Storm Water Drainage System in Khon Kaen University

Abstract

This project aimed to study the suitability of storm water drainage system in Khon Kaen University where located in the Northeast of Thailand, The locations and capacities of storm water collection facilities were considered, The facilities which were existing, under constructing and in the future plan were included, Data involved in the studied area were collected to calculate the rainfall
runoff quantity, Geographic Information System (GIS) was used as a tool in calculation and analysis to assess the water handling capability of the facilities, Some effective solutions were then recommended. 

The studied area was divided into 10 watershed areas. It was found that 5 areas contained collecting ponds, 2 areas contained drainage pipes without collecting ponds and other 3 areas were naturally drained without any management.
It was found from the study that the collecting ponds in 4 of 5 areas were large enough to handle the runoff in the areas, Only the collecting pond which collected runoff from the area around Medical Center Village was not large enough, The drainage pipes in the 2 areas without collectiog ponds were
found to be not capable of carrying the peak runoff in the areas, However, the area around the Faculty Club contained a flood retarrling pond which could handle a 24 minutes-peak-runoff quantity.
