SEOUL, SOUTH KOREA, April 24, 2018 – The Seoul Metropolitan Government announced that large buildings used by 200 or more people should install malodor reduction devices, such as air supply devices, at pumping-type, or forced emission-type, septic tanks no later than the end of September this year.
Those who fail to install them within the period may face up to one year in prison or a maximum 10 million won ($ 9,300) in fines. The city government will focus on publicizing this revision so that the citizens will be fully aware of it.
As of the end of 2017, a total of 2,721 buildings (43%) out of 6,320 have competed the installation of the devices, and the remaining 3,599 will receive customized information and education about the installation of the devices from the city government.
Meanwhile, the Seoul Metropolitan Government had conducted on-the-spot inspections and researches to find out the main causes of sewer smell in order to get rid of possible inconveniences that may be caused to the citizens and visitors.
According to an industry-university research carried out the University of Seoul, the use of an air supply device reduced the concentration of hydrogen sulfide (H2S), which are odor causing substances, to 0.5 to 2ppm from 100 to 350ppm.
The city government also confirmed the effect of the malodor reduction device at septic tanks where air supply devices had been pilot-installed in ten major city areas including Gwanghwamun, City Hall, Myeongdong, Sinchon, Hongdae Street, Seochon, Bukchon, Daehakro, Dongdaemun Market, Namdaemun and Seoul Station. They all reduced the bad smell by 87 percent.
