Chuncheon City to Improve Sewage Plant Sludge Process... Annual Budget Savings of 600 Million Won Expected

Influent Sewage Continues to Exceed Design Specification by 40%
New 3,000-Ton-Per-Day Return Water Treatment Facility to Be Built
Addressing Overcapacity Issues and Laying the Foundation for Stable Operations

Chuncheon City in Gangwon Province will improve its sludge treatment process to address the issues of exceeding the sewage treatment plant’s facility capacity and the water treatment load caused by high-concentration return water.

High-concentration return water generated during the sewage treatment process has been identified as a major factor increasing the load on the water treatment system. In particular, the Chuncheon Public Sewage Treatment Plant has faced significant challenges in handling influent sewage with concentrations (BOD) exceeding the design specification by 40%.

In response, the city plans to invest a total of 1.3 billion won to install a new return water treatment facility with a daily capacity of 3,000 tons, fundamentally blocking the influx of high-concentration return water into the water treatment system. Additionally, by introducing a process to enhance sludge treatment efficiency, the city expects to reduce the amount of return water generated and significantly cut the costs previously incurred for outsourcing sludge treatment.

This improvement project is expected to greatly enhance operational efficiency, including better effluent water quality and reduced outsourcing costs. The city anticipates an annual budget saving of approximately 600 million won.

A city official stated, "This improvement of the sludge treatment process is a project that can resolve the current water treatment overload issue and reduce costs," adding, "We will do our utmost to ensure stable operation of the current facility until the relocation of the Chiljeon-dong Sewage Treatment Plant in 2029."
