The Snyder Industries 4500 Gallon Vertical Storage Tank is a Chowchilla, California-built crosslinked polyethylene (XLPE) tank rated to 1.4 specific gravity, standing 91 inches tall on a 143 x 143 inch footprint. If you are searching for a heavy-duty white vertical storage tank with real density headroom, this is a tank engineered to hold contents heavier than water without pushing the wall to its limit.
Will it work for your site?
At 4500 gallons, a full load of plain water weighs about 37,530 pounds, and the 1.4 SG rating raises the maximum rated contents weight to roughly 52,542 pounds. That density band is the reason to choose this XLPE tank over a standard 1.0 SG water tank: it carries a comfortable margin for water, rainwater, fire-reserve storage, and moderately dense fluids. Because the loaded weight is substantial, plan the pad first. Our concrete pad sizing guide walks the ACI 360R-10 framework for above-ground poly tanks, and the Tank Sizing Calculator and Tank Sizing Guide help you confirm 4500 gallons is the right capacity before you commit. Reserve the full 143 x 143 inch footprint on the slab.
Fittings and access
This vertical tank is configured with a flange, an 18-inch polyethylene threaded and vented fitting, and a manway with a 15-inch access opening for interior inspection and cleaning. Note that a 15-inch opening is a tight access port, so plan cleaning and entry accordingly. Exact fitting positions and elevations are shown on the technical drawing on this page, so verify inlet, outlet, and vent placement against your plumbing plan before install. If this is going into rural fire-water or reserve duty, our fire-water reservoir design guide covers NFPA 22 sizing and freeze protection, and the water-reuse topology guide is worth a read for grey-water and rainwater aggregation trains.
The mistake to avoid
Do not treat the 1.4 SG rating as a license to store any dense chemical. This tank is spec'd for water and water-class service; the density rating is your safety margin, not a chemical-service approval. If your fluid is heavier than 1.4 SG, you need a higher-rated tank, and any non-water service requires a compatibility check against both the XLPE resin and the flange and fitting gasket elastomer before you fill it. Also confirm your fill height matches the 91-inch tank body and leave freeboard for thermal expansion, as covered in the freeboard sizing guide.
