The Snyder Industries 330 Gallon XLPE Vertical Storage Tank (SII-1011600N42) is a white cross-linked polyethylene vertical tank built for heavy liquid duty. It stands 58 inches tall on a 44 x 44 inch footprint, holds 330 gallons, and carries a 1.9 specific gravity rating - so the wall is engineered for liquids up to 1.9 times the weight of water. That puts this XLPE tank a full step above a standard 1.0 to 1.5 SG water tank.
Will it work for your storage job?
This is a vertical storage tank, so it uses floor space efficiently. Filled with water the contents weigh about 2,752 pounds, while the tank is rated to carry contents up to 5,229 pounds - roughly 2,477 pounds of headroom, which is exactly what the 1.9 specific gravity rating buys you for denser liquids. Use those numbers when you plan your stand and pad. If you are sizing for a target volume or checking how a 330-gallon vertical tank fits your space, our Tank Sizing Calculator and Tank Sizing Guide walk through the math step by step.
Cross-linked polyethylene and where it earns its keep
The XLPE construction is a cross-linked resin, which builds more impact and environmental-stress-crack resistance into the wall than standard linear polyethylene. That makes this tank a durable choice for outdoor water storage and reuse duty. If you are engineering a rural fire-water supply, our guide on fire-water reservoir tank design and NFPA 22 sizing covers reserve sizing and freeze protection, and our industrial water reuse topology guide covers grey-water, rainwater, and condensate aggregation trains.
The mistake to avoid
The most common error with a vertical poly tank is skipping the pad detail. At the tank's maximum rating, up to 5,229 pounds of contents bears on the 44 x 44 inch footprint - about 2.7 psi across the base - so the foundation has to be smooth, level, and fully supported edge to edge. An unsupported edge or a point load will stress the wall. Our walkthrough on concrete pad sizing for above-ground polyethylene tanks lays out the ACI framework, and because vapor-side wall stress is where poly tanks often fail first, the ASTM D1998 wall-thickness guide is worth reading first. The fitting and outlet configuration is shown on the technical drawing on this page - confirm the outlet position and bulkhead size against it before you plumb.
