Design intent

The system, in one paragraph.

AquaCore Potable Reserve is a bolted glass-fused-to-steel (GFS) reservoir certified to NSF/ANSI 61 for direct contact with finished potable water. Each steel panel is fired at 1,560 °F to chemically bond a 10-mil vitreous glass enamel — the coating becomes the steel, not a film on top of it. The cobalt interior does not chalk, delaminate, or harbor biofilm; the SS-316 bolted seams are gasketed with an FDA-compliant EPDM profile. Factory-coated panels arrive on a single flatbed and erect in days, not months, with zero field welding and zero field painting. After thirty years of service in the hardest chlorinated water, the interior still polishes clean to the original mill gloss.

Coating service life is warranted — not estimated. No recoats, no refurbishment, no scheduled interior paint. The glass that leaves our furnace is the glass that retires with the tank.
