The Snyder Industries 7900 Gallon ASTM XLPE Vertical Storage Tank is a heavy-capacity vertical storage tank molded from crosslinked linear polyethylene (XLPE) with a 1.5 specific gravity rating, giving you real density headroom above plain water. It stands 177 inches (about 14.75 feet) tall on a 120 x 120 inch footprint (10 feet square) and holds 7,900 gallons in natural white. This is the size class engineers reach for on bulk water storage, fire reserve, and industrial process makeup where a single large vessel beats a manifold of smaller ones.
Will it work for your site?
Filled with water, this tank carries roughly 65,886 pounds of contents; at its full 1.5 SG rating the contents can reach up to 98,829 pounds. That load, not the gallon number, sizes your foundation: pour a level, engineered pad rated for the full 98,829 pounds before the tank arrives. Also plan for the standing height — at about 14.75 feet you need to check door, canopy, and crane clearance for both delivery and offload. Our concrete pad sizing guide walks the ACI 360R-10 framework, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 7,900 gallons is the right volume before you commit to a 10-foot footprint.
Fittings, venting, and access
The tank is configured with a flange fitting, an 18-inch PE threaded and vented top opening, and a manway with 15-inch access for interior entry, inspection, and cleaning. Treat that top opening as the working vent: it must stay unobstructed during fast fill and draw so you never pull a vacuum on the XLPE wall. Confirm the fitting locations and elevations — plus flange gasket material and outlet sizing — against the technical drawing on this page before you rough in plumbing, since outlet height drives your discharge routing and pump suction line.
Usable volume and application
The 98,829-pound figure assumes fill to the 1.5 SG rating, so reserve freeboard per ASTM D1998 — your usable fill sits below nameplate once that allowance is set. The Snyder Captor freeboard guide works the D1998 math and the real volume you can actually use. As an XLPE vertical tank this vessel suits bulk water, rainwater and reuse trains, and reserve storage. For a private fire reserve, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection; for grey-water, rainwater, and HVAC condensate aggregation, the industrial water reuse topology guide maps how a vessel this size fits a quality-banded storage train.
The most common mistake on a tank this large is underbuilding the foundation for water weight instead of the full 1.5 SG rated load, or roughing in plumbing before checking the drawing. This vertical storage tank ships by LTL freight from the Lincoln, NE plant, quoted live to your ZIP.
