Snyder Industries 4500 Gallon ASTM XLPE Black Vertical Storage Tank

The Snyder Industries 4500 Gallon Vertical Storage Tank is built from ASTM-grade crosslinked linear polyethylene (XLPE) in black, rated to a 1.5 specific gravity, and ships LTL freight quoted live to your ZIP. A 1.5 SG rating means the wall is engineered to hold contents up to 50 percent denser than water — the highest-density rating offered for this size, so there is no heavier-rated upgrade to chase for that range. At 143 inches in diameter and 91 inches tall, this is a low-profile, wide-diameter vertical — roughly 11.9 feet across and 7.6 feet tall — that holds 4,500 gallons in a single squat column rather than a tall one.

Will it work for your site?

Fill it with water and you are supporting 37,530 pounds of contents; run it to its full 1.5 SG rating and the tank carries up to 56,295 pounds. Those numbers drive your pad. The 143 x 143 inch footprint is the full outside diameter, so the engineered slab must exceed roughly 12 feet square and be dead level. An above-ground poly tank this size needs that base right — our concrete pad sizing guide walks the ACI 360R-10 framework for this exact load class, and you should size the pad for the full 56,295-pound rated load, not the lighter water figure. To confirm 4,500 gallons is the right column for your draw and refill cycle, run the Tank Sizing Calculator or read the Tank Sizing Guide. The XLPE wall makes this a common pick for bulk water, fire reserve, and reuse-train storage; for rural fire supply the NFPA 22 reservoir design guide covers sizing discipline and freeze protection, and for grey-water aggregation our water reuse tank topology guide lays out quality-banded storage trains.

Fittings and access

The technical drawing on this page shows the fitting layout: a flange fitting, an 18-inch PE threaded and vented top opening, and a manway with 15-inch access for interior entry, cleaning, and inspection. Verify each fitting size and elevation against the drawing before you plumb, because moving an outlet on a filled 4,500-gallon column is not a field fix. Also confirm the manway lid gasket and flange gasket material suit your contents and temperature — the 1.5 SG XLPE wall rating does not by itself cover those elastomer seals.
