Hansung Cleantech Wins 22.2 Billion Won Pyeongtaek P5 UPW System Contract... Order Rally Accelerates Amid AI Expansion

Hansung Cleantech has once again demonstrated its competitiveness in the semiconductor water treatment EPC business by securing an additional contract for an ultrapure water (UPW) system construction project related to Samsung Electronics' Pyeongtaek semiconductor production line.

Hansung Cleantech, a company specializing in industrial water treatment and ultrapure water facilities, announced on June 18, 2026 that it had been awarded a contract by Samsung E&A for the installation of the UPW system for the P5 project at Samsung's Pyeongtaek semiconductor plant.

This contract covers the installation of the UPW system for Phase 1 of the Pyeongtaek Campus P5 project, with the contract amount reaching approximately 22.2 billion won.

The UPW system is a core facility that produces and supplies high-purity water used in wafer cleaning and other semiconductor manufacturing processes. As semiconductor processes become more advanced and production complexity increases, the importance of impurity management and stable UPW supply grows, driving continued expansion in demand for related infrastructure.

This contract is particularly significant because it represents an additional follow-up project secured after the previous wastewater treatment system construction within the Pyeongtaek P5 project.

Previously, Hansung Cleantech secured cumulative orders worth about 16.4 billion won through a change order for the P5 Green Building wastewater treatment system installation. With the addition of the current UPW system contract, the company has expanded its business scope within the Pyeongtaek P5 project.

Recently, the global semiconductor industry has seen intensifying competition to expand production capacity in response to growing demand for artificial intelligence (AI) semiconductors and high bandwidth memory (HBM). Accordingly, major semiconductor companies are increasing investments in new production facilities and process infrastructure, and the semiconductor water treatment market—including UPW and wastewater treatment facilities—is expected to maintain its growth trend.

In particular, as semiconductor processing technology becomes more sophisticated, the quality and stability of UPW used in wafer cleaning are considered key factors that determine product yield.

Hansung Cleantech has strengthened its competitiveness as a domestic company in the semiconductor UPW market—traditionally led by global engineering firms—by leveraging its technological capabilities and project execution experience.

The company has built a diverse portfolio by undertaking UPW and wastewater treatment projects at major semiconductor sites, including the Pyeongtaek semiconductor campus, Yongin semiconductor cluster, and DB HiTek's system semiconductor plant.

Recently, the company has also been working on developing energy-saving UPW plant design technology through national projects, aiming to secure a competitive edge in next-generation water treatment technologies.

A Hansung Cleantech representative stated, "With the expansion of the AI semiconductor market, investments in memory and system semiconductor production facilities are continuously increasing. We will actively pursue additional contract opportunities based on our comprehensive water treatment EPC capabilities, covering both UPW and wastewater treatment."

Hansung Cleantech plans to expand its growth opportunities by leveraging its UPW and water treatment EPC business in line with the ongoing investment surge in the AI and HBM-driven semiconductor industry.
