SEOUL, SOUTH KOREA, September 13, 2021 – The Seoul Metropolitan Government will designate ten venues for the Smart Water Circulation City project by 2030 in an effort to make the best use of unused-but-discarded water resources by utilizing IT technologies in managing the water resources in an integrated manner.
The Smart Water Circulation City project is designed to integrate various water circulation facilities to utilize the water resources collected from rainwaters, spilled underground waters, and heavy waters tailored to regional characteristics.
The city government applies advanced IT technologies for monitoring and making integrated management of the facilities. It also plans to publicize the project and its effects so that the citizens can be more aware of it.
With this project, the Seoul Metropolitan Government aims to maximize the usage of the water resources in order to achieve environmental effects – for instance, saving the sewage treatment cost, restoring the value of water circulation, lessening the heat island effect, reducing the fine dust, and enhancing the surrounding landscapes.
Seoul already selected the area in Sangbong-dong, Jungnang-gu, in April, as its first project venue.
It announced to conduct a public contest to designate the second one by November 30. The selected venues will receive KRW 3 billion (USD 2.56 million) in total as a project budget. The basic design work is underway in the first project venue in Sangbong-dong.
The Smart Water Circulation City project is expected to reap economic benefits of annual saving amounting to KRW 700 million (USD 598,290), including KRW 200 million of the yearly sewage fee and KRW 500 million of the treatment cost the Jungnang Water Recycling Center had usually spent.
The first venue will be equipped with a “planter box,” a nonpoint pollutants reduction facility, to purify road runoff, and together with a facility that helps rainwater permeating through the ground to achieve better permeability. In addition, some facilities will be installed so that rainwater can be utilized to boost road cooling and cooling fog effect. Smart sensors will also be attached to each facility unit so as to monitor the level of rainwater permeability.
By the end of this year, Seoul will select the second project site and then start detailed design and construction in next year so that it can conduct the integrated management of water resources based on IT technologies starting from 2023.
The city government will select the remaining project venues after reviewing if the place has over 70 percent of imperviousness rate; if it has more than 100 tons of daily use of leaked underground water; if it collectively installed rainwater management facilities; and if it provides meaningful water-friendly spaces for citizens.
The candidate venues are required to provide the needed information using various channels including digital signages showing the volume of water savings, the amount of sewage treatment cost reduction, and so on, to make sure that citizens can have an easy access to the city’s water circulation policy.
“The Smart Water Circulation City project will enable us to manage water resources in an integrated manner using IT technologies and contribute to opening up a new era of smart water circulation,” said Han Yoo-seok, Director-General of Water Circulation Safety at the Seoul Metropolitan Government. He added, “We expect as many as autonomous districts to participate in the contest with brilliant ideas because this project can help achieving a great environmental and economic effects in the city.”
