[Installation Update] Cheorwon Girls’ High School (Gangwon), Adopts BLOS—GeoGrid’s Smart Water Quality Management Solution
From cafeteria cooking water to drinking water, setting a new benchmark for school water infrastructure

Cheorwon Girls’ High School in Cheorwon, Gangwon Province, has officially adopted GeoGrid’s smart water quality management solution, BLOS (Building Oasis), to provide students with a safer and cleaner school meal environment.

Background: A School’s Decisive Move to Put Student Health First

Cheorwon Girls’ High School has long placed exceptional emphasis on student health and hygiene. This decision to implement BLOS was driven by the school’s proactive commitment to upgrading its educational environment—preventing water quality deterioration caused by aging pipes and ensuring thorough management of even the “invisible” water infrastructure before issues arise.

Results: A Water-Purifier-Free Cafeteria, With Peace of Mind Backed by Data

Immediately after implementation, the school cafeteria began receiving “daily-life purified water” across all taps—covering cooking water, tray and dishwashing, and student drinking water—without the need for separate, individual water purifiers at each point of use.

One-Stop Installation: Installation was completed quickly without disrupting the academic schedule, and building-wide water quality improvements were evident immediately after commissioning.

Real-Time Monitoring: With BLOS’s smart sensors, the school can manage water quality status and water usage in real time—enabling reliable control of hygiene even inside the hidden plumbing network.

Eco-Friendly Maintenance: By suppressing scale and rust formation without chemical additives, BLOS maximizes the efficiency of facility operations and maintenance across the campus.

Evidence of Thorough Hygiene Management: “Clear and Clean—Even Where You Can’t See”

Before incoming source water reaches the kitchen, the BLOS system acts as a frontline guard—capturing unseen particulates and contaminants along the way. Findings confirmed through routine filter inspections further demonstrate the strength of the school’s decision to adopt BLOS.

“A school’s meticulous management creates a healthy table for our children.”
This shows BLOS centrally filtering fine particulates and debris inside the plumbing—things that are difficult to detect with the naked eye. It also serves as a reassuring indicator of the school’s commitment to providing students with high-purity water.

On-the-Ground Feedback

A school representative commented, “We decided to adopt this system because we believe water is the foundation of the meals students eat every day. With purified water supplied throughout the entire kitchen, hygiene management has become much easier. Most importantly, we’re very satisfied that we can provide students with healthier water.”

🚀 Bringing the Future of Water Quality Management Closer with BLOS

GeoGrid’s BLOS (Building Oasis) goes beyond a simple filtration device—it intelligently transforms the water infrastructure of educational facilities where our children spend their day. Building on the Cheorwon Girls’ High School installation, we will continue to lead the way toward a new era of tap water that can be safer than point-of-use water purifiers across schools nationwide.
