1Investment overviewGEOGRID

BLOS is installed at schools, a corporate campus, a residential building and public facilities in Korea, Indonesia and Bangladesh

1The building water gapGEOGRID

Water quality can change after water enters a building

Animated concept: incoming water passes BLOS treatment, then distributes through a school 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.

1Global demandGEOGRID

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.
