The Snyder Industries 5500 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a large-format polyethylene vertical tank built for bulk water and high-density liquid storage where standing capacity and a solid rated wall matter more than portability. It stands 221 inches tall on a 90 x 90 inch square footprint, holds 5,500 gallons, and carries a 1.9 specific gravity rating, so it is engineered to hold liquids substantially heavier than water at full volume. The black exterior blocks light to slow algae growth, which is why this Snyder vertical storage tank shows up under searches for a black storage tank when the stored liquid needs to stay dark.
Will it work for your site?
Fill weight is the number that decides your pad and your site plan. Filled with water this tank carries roughly 45,870 pounds; at its full 1.9 SG rating the contents alone can reach about 87,153 pounds. That load rides on a 90 x 90 inch base, so the pad underneath has to be sized and level for it — run your numbers through the Tank Sizing Calculator and the Tank Sizing Guide, and read the concrete pad sizing framework before you pour. Keep in mind that a rated 5,500 gallons is not all usable working volume — a vertical storage tank needs freeboard above the liquid line, and the freeboard sizing guide walks through how to figure the volume you can actually draw.
Fittings and plumbing
The top plumbing on this model gives you room to build an inlet, vent, and access in one platform:
- 18-inch PE threaded and vented top fitting
- Flange fitting
- S.U.M.O. fitting
- Manway with 15-inch access
- Fitting flat located at 272.5 degrees
Exact fitting sizes and elevations are shown on the technical drawing on this page — confirm them against your plumbing before ordering.
Common mistake to avoid
The 1.9 specific gravity rating is the ceiling for what this wall is designed to hold, not a suggestion. If your liquid is denser than water — many process and reuse streams are — verify its specific gravity stays within that 1.9 rating before you commit. For water reuse and blended storage trains, the industrial water reuse tank topology guide covers how to band quality by tank, and rural fire-water buyers should read the NFPA 22 reservoir design guide for freeze protection and sizing discipline.
Freight
This tank ships by LTL freight from Snyder's plant in Lincoln, Nebraska, quoted live to your ZIP. At 221 inches tall on a 90 x 90 inch footprint, a tank this size moves as its own freight shipment, so your delivery location drives the cost.
