Yongin City Completes Giheung Respia Wastewater Treatment Plant Upgrade Project

Expecting Water Quality Improvement Around Giheung Lake with 17.3 Billion KRW Investment in Flow Regulation and Bioreactor Expansion

Yongin City in Gyeonggi Province announced on the 13th that it has completed the advanced treatment facility upgrade project at the Giheung Lespia Public Sewage Treatment Plant, located upstream of Giheung Lake, and will start operation from the 14th.

The Giheung Lespia Public Sewage Treatment Plant is a facility responsible for treating sewage flowing into the upper stream of Giheung Lake. The city began the project in 2020 with a total investment of 17.3 billion KRW, including 8.5 billion KRW in national subsidies, and completed the construction in just over three years.

To treat high-concentration inflow sewage, the city added a 6,000-ton flow regulation tank and expanded the biological reaction tank by 8,000 tons through the construction. As a result, the water treatment retention time has been sufficiently secured, and nitrogen and phosphorus, which are the main causes of water quality deterioration, can now be efficiently removed, the city explained.

The city has completed the separation work of stormwater and sewage pipes at Giheung Lespia to manage the water quality of Giheung Lake and has been working on improving water quality by installing total phosphorus treatment facilities.

An official from Yongin City Sewage Business Office said, "We have strengthened the water treatment facility functions to improve the water quality of Giheung Lake, a representative attraction of Yongin. We will continue to strive to improve the facilities to provide citizens with a clean and safe waterfront space."

Meanwhile, Giheung Lake, located in the Hagal, Gongse, and Gomae neighborhoods of Giheung-gu, Yongin City, covers an area of 2.5 square kilometers and is the third-largest reservoir in the metropolitan area after Idong (Cheoin-gu, Yongin) and Gosam (Anseong). Originally created to supply water to surrounding agricultural facilities, it is now mainly used as a leisure space for citizens due to rapid urbanization. A 10-kilometer-long walking trail has been established around the reservoir.
