The Snyder Industries 4100 Gallon Vertical Storage Tank is a crosslinked linear polyethylene (XLPE) vertical tank built for high-density bulk water and liquid storage where a standard polyethylene wall would be undersized. It carries a 1.5 specific gravity rating - the number that decides whether this tank is right for your liquid - on a 120 x 120 inch footprint. Note the 120-inch diameter exceeds the 100-inch height: this is a wide, low-profile vessel, not a tall column, so plan your pad, clearance, and offload around a squat 120-inch-diameter tank.
Will it hold your liquid?
At 4,100 gallons of plain water this tank carries roughly 34,194 pounds of contents, and its 1.5 specific gravity rating lets it hold up to about 51,291 pounds of denser liquid at full volume. That headroom is why an XLPE vertical storage tank like this one is specified for liquids heavier than water rather than a lighter, single-wall polyethylene vessel. The Natural White XLPE wall and the 120 x 120 inch footprint tell you the pad size you need before the tank arrives. Use the Tank Sizing Calculator and the Tank Sizing Guide to confirm the 4,100-gallon working volume against your fill-and-draw cycle, and review concrete pad sizing for above-ground polyethylene tanks so the slab under 51,000-plus pounds is engineered correctly.
Fittings and access
The tank comes with an 18-inch PE threaded manway for top access and cleanout, a flange fitting, and eight blank flat fitting pads set at 45-degree radial spacing around the tank. Those pads are not pre-tapped: each must be drilled and fitted with a bulkhead fitting and a gasket rated to the liquid you are storing, and a bolted outlet flange seals differently than the PE threaded manway. Because the eight pads sit at fixed 45-degree clock positions rather than anywhere on the wall, rotate the tank to align a pad with your existing plumbing before you set it. Confirm every connection point against the technical drawing on this page before you run pipe.
Sizing for fire-water and reuse duty
A 4,100-gallon vertical tank at this capacity is a common building block for private fire-water reservoirs and industrial water-reuse trains. If this tank is going into fire protection service, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For grey-water, rainwater, or HVAC condensate aggregation, the industrial water reuse tank topology guide walks through quality-banded storage trains. The one mistake to avoid: do not assume this XLPE tank's 1.5 specific gravity rating lets you skip a proper freeboard and pad calculation on a dense liquid - review the freeboard sizing guide before you commit.
This tank ships LTL freight from the Snyder plant in Marked Tree, Arkansas, quoted live to your ZIP. The empty tank moves on a flatbed, and at 120 inches wide it can push into over-dimensional handling, so confirm wide-load offload with forklift or crane access at your site before you order.
