[Installation Update] Suwon Jungang Christian Elementary School Adds “Transparent Peace of Mind” to Every Classroom

A special change has arrived at Suwon Jungang Christian Elementary School—where children should be free to play, learn, and grow in good health. On December 12, 2025, BLOS (Building Oasis), GeoGrid’s smart water quality management solution, was installed in the school’s facilities room—an intelligent guardian designed to protect student health around the clock.

🏫 A School Built on Trust—Now Proving Water Safety with Data

Jungang Christian Elementary School has consistently led efforts to create the best possible educational environment for its students. Adopting BLOS is not only about delivering better water; it is a decision to create an environment where children can feel safe—by monitoring and transparently showing, in real time, how clean the water they use truly is.

In particular, a standing monitor installed at the school translates complex mechanical-room data into a child-friendly UI that students can understand at a glance. By openly sharing the real-time status of the school’s tap water, the school has created an environment where children can trust and comfortably use the water every day.

🛠️ Seamless Installation Combined with an Emergency Purification System

The installation process was carried out systematically with safety as the top priority. After separating the existing piping, the system was reconnected using highly durable stainless-steel piping, and a complete by-pass system was built to allow water supply to be rerouted in the event of an abnormal situation.

Smart Water Quality Surveillance: Precision sensors measure five key indicators in real time—turbidity, oxidation-reduction potential (ORP), pH, electrical conductivity (EC), and residual chlorine (RC).

Dual Safety Mechanism: If the secondary sensor detects even a slight abnormality, the system is designed to activate immediately and perform emergency purification through a microfilter.

Thorough Performance Verification: During commissioning tests conducted immediately after installation, the system recorded a 0% data packet loss rate, confirming stable and flawless communication with the central server.

📊 Clear Improvements Confirmed by Data

The water quality results before and after installation were remarkable. In particular, turbidity and residual chlorine levels improved significantly compared to pre-installation measurements, while both total coliforms and general bacteria were not detected—confirming a clean and hygienic condition. Not only did all indicators meet drinking-water quality standards, but the outcome also provided the highest level of reassurance for the entire school community.

⚙️ Thoughtful Maintenance That Never Stops—365 Days a Year

At Jungang Christian Elementary School, BLOS is managed even more carefully after installation.

Daily: Anyone can view 24/7 real-time water quality data at any time.

Monthly: Sensor cleaning and precision zero-point calibration are performed to maintain data reliability.

Quarterly & Annually: In addition to filter replacement and inspection of pipe connections, an annual comprehensive water quality test is commissioned to keep system performance at its best.

A school should be the safest environment where children learn how to step out into the world. Jungang Christian Elementary School and GeoGrid will manage even the unseen plumbing with transparent, data-driven control—so that every glass of water children drink carries the value of peace of mind.
