Gangdong-gu Gildong Station and Godeok Station Groundwater Road Cleaning Recycling

New 'Water Hydrants' Installed for Road Cleaning at Gildong Station and Godeok Station... Expected to Alleviate Water Shortage for Cleaning and Reduce Urban Fine Dust and Heat Island Effect

The water supply valve at Godeok Station is being pilot operated after its completion.

[Asia Economy Reporter Jongil Park] Gangdong-gu (Mayor Lee Jeong-hoon) has installed water supply points at Gildong Station and Godeok Station to recycle discarded groundwater for use in street cleaning.

This will secure approximately 12,000 tons of groundwater annually, which is expected to not only resolve the chronic water shortage but also contribute to realizing a clean Gangdong.

Street cleaning washes away fine dust in urban areas and helps alleviate the heat island effect. Although the district conducts daily street cleaning, it has faced difficulties in securing water supply.

Among the four water supply points used to draw water, three were too far away to be practically used, and relying solely on the supply point installed at Gubeundari Station was insufficient to cover the entire district's cleaning water needs.

Additionally, outdoor fire hydrants (connected to the water supply) ? another water source ? can only be used in emergencies such as fine dust alerts or heatwaves, so the need to expand water supply points has been continuously raised.

In response, Gangdong-gu focused on the fact that about 12,000 tons of first-grade groundwater generated at Gildong and Godeok stations is discharged into the sewage system, and after continuous consultations with Seoul Metro Corporation, installed the water supply points.

A 7HP (horsepower) submersible pump was installed in the subway drainage pump room reservoir to lift water to the surface, with a budget of 107.4 million KRW invested.

Lee Jeong-hoon, Mayor of Gangdong-gu, said, “Now, without using outdoor fire hydrants, we can sufficiently secure the water needed for street cleaning with just the water supply points, which is expected to save 17 million KRW annually by not using fire hydrants. Going forward, we plan to utilize the discarded groundwater not only for street cleaning but also for urban agriculture and other purposes.”
