Name

Arisu was named in 2004, the former name for Han River in ancient Goguryeo, with the combination of 'Ari,' which means 'big' in Korean, and 'Su,' meaning, 'water.' It is also the name of the water treatment plant located in Seoul, South Korea.[1]

Quality and Supply

Water source management

Because Arisu is supplied to all areas of the city of Seoul, it is very strictly administered by the water treatment plant. The Seoul Metropolitan Government engages in 24-hour real-time protection and surveillance of the water source to deliver clean and safe tap water. Regular assessments are made of 41 different indicators at 33 water source points and 135 indicators at the six water intake points. Seven indicators, including algae (chlorophyll-a) and phenol, are especially monitored automatically around the clock. The Guui plant operates a biological early warning system using water fleas in addition to installing barriers to block oil from flowing into the water source. It is being served to more than ten million people living in Seoul and the metropolitan region of South Korea. Households with low-income are provided with 21 million bottles of Arisu.[1]
