The Snyder Industries 16500 Gallon XLPE Vertical Storage Tank (SKU 5380000N40) is a crosslinked linear polyethylene (XLPE) vertical storage tank built for high-density bulk water and heavy liquid storage. It stands 257 inches tall on a 142 x 142 inch base, molded in Natural White, and carries a 1.5 specific gravity rating - meaning the wall is rated for contents heavier than water, not just plain water service. If you are sizing a large above-ground vertical tank for a rural fire reservoir, an industrial water reuse train, or general bulk storage, this is a large-format XLPE vertical.
Will it work for your site?
Plan your slab for two loads: about 137,610 lb with plain water (specific gravity 1.0), and about 206,415 lb at the full 1.5 SG rating - the ceiling this shell is engineered to hold and the number to design around if you are storing anything denser than water. The 1.5 SG rating is the highest wall rating offered on this XLPE vertical, so that maximum contents figure is the true design limit. Both loads land on an engineered slab; a tank this size is not a set-it-on-gravel install. Size the width figure too - 142 inches is the single base dimension you measure for gate, door, and slab clearance. Work the pad against our concrete pad sizing framework (ACI 360R-10 / ACI 318) before you pour, and confirm usable volume with the Tank Sizing Calculator and Tank Sizing Guide.
Fittings and access
Per the technical drawing on this page, the tank is configured with a flange fitting, a 12" x 26" fitting, an 18" polyethylene threaded and vented fitting, a manway with 15" access, and a flat fitting landing. The bolted flange and manway are gasketed connections - verify gasket material and bolt torque against your service liquid before commissioning. Confirm each outlet size and its clock position against the technical drawing and your piping plan before delivery, since fitting locations are molded in and cannot be relocated in the field. The 15"-access manway is your entry point for cleanouts and internal inspection.
Common sizing mistake to avoid
The mistake buyers make on a 1.5 SG XLPE vertical is under-reading the freeboard and foundation demands at scale. Because the wall is rated to 1.5 SG you can fill it with dense liquids, but that 206,000-plus-lb maximum drives both your foundation design and your working volume. If this is a fire-water reservoir, size the standing volume with reserve discipline - our NFPA 22 fire-water reservoir guide covers reserve sizing and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, our industrial water reuse tank topology guide walks through quality-banded storage trains.
