The Snyder Industries 35 Gallon HDPE Vertical Liquid Storage Tank is a compact, white polyethylene vertical tank for above-ground water and general liquid storage. It stands 36 inches tall on a 22 x 22 inch square footprint, so it slips into tight utility rooms, equipment skids, truck beds, and pump houses where a larger-diameter tank simply will not fit. At 35 gallons it is sized for day-tank duty, rinse water, and remote-site reserve rather than bulk storage. If you are unsure whether 35 gallons covers your draw, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you order.
Will this Snyder vertical tank work for your install?
The tank is molded from polyethylene and carries a 1.9 specific gravity rating, which means the wall is built to hold liquids up to 1.9 times the weight of water without overstressing the shell. Filled with plain water, the contents weigh about 292 pounds; at the full 1.9 SG rating the shell is engineered to carry up to 555 pounds of contents. That 1.9 rating is genuine headroom most 35-gallon water tanks do not carry, so this same shell handles heavier-than-water solutions such as brine up to 1.9 SG without stepping up to a different model. This tank has exactly two openings: a 6-inch PE threaded, vented inlet up top and a cap with a 4.5-inch access port for hand-fitting, level checks, and cleanout. There is no separate bulkhead outlet in the drawing fittings - all fill, vent, and access run through the top - so plan a pump or siphon draw, or order an outlet bulkhead and gasket separately. Confirm both connection sizes against your plumbing on the technical drawing on this page before you cut any pipe, and make sure any 6-inch PE-threaded adapter seats with its gasket against the threaded boss and that the 4.5-inch access cap has its sealing gasket in place before you fill.
The mistake to avoid
The most common error on a small HDPE tank like this is overfilling past the rated load. The 1.9 SG rating is a ceiling, not a suggestion - at 1.9 SG the 35 nominal gallons reach the 555-pound contents ceiling, so plan your fill level against the actual weight of what you are storing, not the gallon lines on the wall. Respect the freeboard at the vapor-saturated headspace, where HDPE walls thin first. Two reads worth your time: HDPE tank wall thickness at the vapor-saturated headspace and the ASTM D1998 freeboard sizing breakdown.
Mounting and footprint
Because this is a vertical storage tank with a low 22-inch diameter, the loaded weight rides on a small base - up to about 555 pounds across a 22 x 22 inch (3.36 square foot) footprint. Set it on a flat pad or skid that is fully supported under the entire footprint, with no overhang at the edges. For the engineering framework, see our guide on concrete pad sizing for above-ground polyethylene tanks.
