Busan,rainwater reservoir the size of a football field to one trillion prevent flooding

Gukjiseong frequent extreme weather events due to heavy rains to prevent the size of a football field in Busan, built up there, is a large underground reservoir. When heavy rains the water does not fall properly, Busan city drainage system in order to compensate for the limitations of the stand. The facility's drainage capacity of storm sewer by heavy rain when the rain water out to prevent flooding by temporarily storing should function.

Busan, the country spent fertilizing 9,560,000,000 won Olympic Park, Woo 1-dong, Haeundae-gu, 40m length, 95m width, height 6m space underground 1 만 8200t Centum earth where you can store rainwater retention basins superior to last month, 17 days after jungonghan Geumjeong Pusan 20,000 in the second basement yard capacity of 8800t woosujeoryujo said three days she went into construction work. The city of Busan, and Hankuk University of Foreign Studies The new campus site Geumjeong, Geumjeong elementary school playground, Yeonje Hall parking lot and parks, parking lots and parks, Ottawa Police to four additional superior retention basins will erect.



Centum excellent reservoir one trillion last month, the 27th District and torrential rains in the first run in. My role has gained a reputation Dunmow. Haeundae district office building and choehongyun jumugwan the "time in Haeundae average hourly 63 ㎜ Total 168 ㎜ have got off, sewage does not handle rain 4180t and excellent reservoir one trillion them on the mulnanri avoided," said "Good reservoir up there, if it was not flooded it would have been," says said.

Pusan ​​city storm sewer drainage system of the trunk 10 years, the frequency of rainfall (75 ㎜), a 5-year rainfall frequency feeder sewers (65 ㎜) are designed, in the 27th month as a 8 am sikke heavy rain falling per hour by 96 ㎜ (Awake Sept. 28, eight-sided press party) has limited abilities to prevent. Design rainfall frequency of 10 years comes once a decade, was designed to accommodate heavy rains means.



City last April to install a new drainage system for at least 10 years, up to 30 years applies to the frequency of rainfall, but insufficient to prevent heavy rains geril Castle is the intellectual.



But hundreds of billions of increasing the capacity of storm sewer drainage system takes the original budget and a high cost-effective because the underground reservoir excellent facilities to prepare for torrential rains gukjiseong has emerged as an alternative.
