BLOS is installed at schools, a corporate campus, a residential building and public facilities in Korea, Indonesia and Bangladesh
BLOSBuilding Oasis
Filtration and disinfection configured to each building's source water, with sensors, operating records and scheduled maintenance.
Sites by type, October 2026
Water quality can change after water enters a building
Shared exposure
One building supplies classrooms, kitchens, restrooms and other common facilities.
Fragmented management
Operators need both treatment and one clear record of conditions across the building.
Drinking outlet checks
Lead sampling must include relevant taps because internal plumbing can add lead downstream.
Water access and emerging contaminants create demand across regions
1 in 4 people worldwide
WHO/UNICEF JMP. Each dot represents 1% of the world population.
Quality in established water networks
EU monitoring and limit values for PFAS in drinking water apply from January 2026. Building plumbing needs attention too.
Reliable service for shared facilities
Schools, public buildings and hospitality sites need treatment matched to local conditions and ongoing support.
These are indicators of need, not a market size. BLOS targets facilities with a viable water supply, operating capacity and a funded service plan.
BLOS links treatment, disinfection, measurement and maintenance in each building

October 2026 · Confidential discussion draft
Operational sensing and contaminant verification serve different purposes
| Layer | Purpose | Measurement / acceptance |
|---|---|---|
| Connected operations | Track equipment and operating conditions | Sensor records, uptime and response logs |
| PFAS treatment | Reduce selected compounds in the water | Independent laboratory methods and capacity testing |
| Lead management | Address source water and relevant outlets | Influent and effluent testing plus representative tap sampling |
| AI functions | Support maintenance and anomaly response | Alert accuracy, false-alarm rate and response time, measured on operating sites |
PFAS adsorption requires a documented spent-media replacement and disposal plan.
Invoiced work, operating sites, demonstrations and proposals are reported separately
| Reference | Evidence available | Status used in this deck |

| Public schools (education offices) | Six projects in the 2026 invoice ledger | Invoiced Ordered in 2025, invoiced in 2026; maintenance free of charge |
| Resort maintenance | Nine monthly invoices, January to September 2026 | Invoiced Fee-based maintenance, one customer |
| Schools operating BLOS | Site records for 12 schools in Korea | Operating Includes sites without paid service |
| Samsung Electronics Digital City | Site and inspection records | Operating Groundwater line; second-phase ionizer in progress |
| Wisma Indah apartment, Jakarta | Site record | Installed Overseas residential site |
| Bangladesh KOICA CTS | Installation announcement, August 2026; KRW 200M project invoicing | Demonstration Six-month evaluation planned |
| Samsung C&T projects | Project records for Raemian, India, Egypt and Saudi Arabia | Opportunity No signed supply contract |
| Hyatt / Splas / Namyangju | Customer-specific proposal documents | Proposal Excluded from traction |
The ODA program can show both access and operating reliability
| Measure | Method | Why it matters |
|---|---|---|
| People served | Document unique users and facility utilization | Separate estimated reach from observed use |
| Water quality | Compare baseline and follow-up laboratory results | Verify the relevant local water-quality outcomes |
| System reliability | Record uptime, failures and service response | Demonstrate continuous availability |
| Local maintenance | Log operator training, spares and service visits | Support continued operation after demonstration |
| Affordability | Track actual operating cost and funding responsibility | Make the long-term service plan explicit |
Public benefit is measured at the facility. Commercial replication depends on a funded service model.
