Seoul Gangbuk Arisu Water Purification Center Completes Expansion of 'Advanced Water Treatment Facility'... "Enhancing Water Supply Stability"

Preparing for increased water usage due to rapid climate change and expanded water supply in adjacent areas

On the 11th, officials from the Seoul Metropolitan Waterworks Headquarters and the construction company are drinking Arisu produced by the expansion of the advanced treatment facility at the Gangbuk Arisu Water Purification Center.

[Asia Economy Reporter Lim Cheol-young] The daily capacity of the advanced water treatment facility in Seoul will increase from 3.57 million tons to 3.8 million tons, an increase of 230,000 tons. The increased production from the facility expansion will be supplied not only to the supply area of the Gangbuk Arisu Water Purification Center but also to support the water supply of purification centers south of the Han River, enhancing the overall water supply stability of Seoul.

On the 12th, Seoul City announced that it will expand the daily production capacity of the advanced water treatment facility at the Gangbuk Arisu Water Purification Center by 230,000 tons and begin water flow to prepare for rapidly changing climate and environmental conditions. Advanced water treatment adds ozone disinfection and granular activated carbon (charcoal) filtration processes to the existing water purification process, effectively treating trace organic substances such as odor-causing compounds (2-MIB, geosmin) and disinfection byproducts.

Even during the summer, when water usage is high, it is expected that advanced treated tap water can be stably supplied to 112 neighborhoods in 10 districts including Gangbuk, Nowon, Seongbuk, and Eunpyeong, which are the supply areas of the Gangbuk Arisu Water Purification Center. Among the 514 water purification plants registered in the National Waterworks Information System, the Gangbuk Arisu Water Purification Center ranks third in facility capacity nationwide, following the Seoul Amsa Arisu Water Purification Center, the largest in Korea, and Deoksan Water Purification Plant in Gimhae, Gyeongnam.

This capacity expansion of the Gangbuk advanced water treatment facility was promoted to establish a stable tap water production system in response to increased tap water usage due to rapidly changing climate and environmental conditions and to prepare for expanded water supply to neighboring cities (Namyangju and Guri).

Located in Namyangju, Gyeonggi Province, the Gangbuk Arisu Water Purification Center completed the introduction of the advanced water treatment facility (720,000 tons/day) in December 2014 and has been stably supplying an average of 680,000 tons of tap water daily to the northern Seoul area. However, due to changes in the water supply environment, an expansion of the advanced water treatment facility capacity became necessary. The summer tap water supply volume approaches the advanced treatment capacity (720,000 tons/day), and large-scale development plans in neighboring cities are expected to increase future demand, making capacity expansion necessary.

Seoul City carried out the expansion construction of the advanced water treatment facility over 15 months from December 2020 to February this year and confirmed water quality and production facility safety through a three-month trial operation from February to April. The increased production capacity from this expansion will also be used to support water supply at the Amsa and Yeongdeungpo Arisu Water Purification Centers, which have high production and supply load rates, through future water supply system adjustments.

Gu Ami, Head of Seoul Waterworks Headquarters, said, “Our city is systematically maintaining production facilities to stably supply healthy and delicious Arisu despite various climate and environmental changes such as heatwaves, droughts, and green algae blooms,” adding, “We will do our best to ensure citizens can trust and drink Arisu through thorough water quality and process management.”
