[Installation News] Seoul Inchang High School Adopts BLOS (Building Oasis) System
Building a Smart Water Purification Infrastructure for Improved Cafeteria Water Quality

Inchang High School, located in Seoul, has introduced GeoGrid’s smart water quality management solution, BLOS (Building Oasis), to enhance the hygiene and safety of water used for student meals and food preparation.

The installation project was carried out with the goal of supplying clean, purified water throughout all cafeteria facilities without the need for separate purifiers.
This not only addressed concerns over aging plumbing and tap water quality but also significantly reduced the cost and manpower required for purifier maintenance and filter replacement.

BLOS goes beyond being a simple purification device—it is an integrated water management system that continuously purifies tap water throughout the building and allows real-time monitoring of water quality.
At Inchang High School, the system was applied to all cafeteria areas, including cooking stations, washing sections, and water supply lines, and was completed in just one day without disrupting the academic schedule.

A school representative commented,

“Both students and staff can now use water with greater confidence, and the overall operation has become much more efficient.”

BLOS aims to expand its implementation to schools and public facilities across the nation, setting a new benchmark for smart and sustainable water infrastructure.
