High-Quality Tap Water with Advanced Purification Treatment Coming to Cheoin District of Yongin City

[Suwon Ilbo=Reporter Park No-hun] Starting from the end of September, high-quality tap water treated with advanced purification will be supplied throughout the Cheoin district of Yongin City.

Yongin City announced on the 1st that the advanced water purification facility installation project at the Yongin Water Purification Plant in Mohyeon-eup, Cheoin-gu, has reached 92% completion.

The Yongin Water Purification Plant is a local water supply system that produces 100,000 tons of tap water per day and supplies it to all of Cheoin-gu. Meanwhile, the Suji and Giheung regions receive tap water from the metropolitan water supply managed by the Korea Water Resources Corporation. The metropolitan water supply already introduced advanced water purification facilities in 2016.

However, there were concerns that water quality at the intake source, Paldang Water Source, frequently changes due to climate change and algae blooms during dry seasons, which compromises tap water quality in terms of taste and odor.

In response, the city began installing advanced water purification facilities in May 2016, investing a total of 19.1 billion won, including 13.3 billion won in national funds and 5.8 billion won in city funds.

The advanced water purification facility being introduced will newly establish a pre-ozone contact basin capable of advanced oxidation treatment of heavy metals, microorganisms, and organic matter that are difficult to remove through standard water purification processes, and will upgrade existing filtration tanks to activated carbon filtration tanks with enhanced adsorption capabilities.

Currently, 5 out of 6 existing filtration tanks have been upgraded, and the remaining work is expected to be completed by the end of September after test operations following the finalization of other processes.

Once the advanced water purification facility is completed, the city expects to efficiently respond to emergency water quality incidents such as heavy metal discharge from upstream intake sources or sudden deterioration of water quality, as well as to supply citizens with high-quality and safe tap water.

A city official said, "We will expedite the completion of the project to supply safe and clean tap water to all of Cheoin district and enhance citizen trust and satisfaction in tap water."
