Snyder Industries 550 Gallon ASTM Black Heavy Duty Vertical Storage Tank

The Snyder Industries 550 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a 550-gallon black vertical storage tank molded from high density linear polyethylene (HDLPE), standing 75 inches tall on a 48-inch by 48-inch footprint.It carries a 1.9 specific gravity rating, which is the number that matters most on this tank: it is built to hold contents substantially heavier than water, so you have real headroom whether you are storing water, bulk liquid, or a denser solution.

Will it work for your job?

Filled with plain water, this tank carries roughly 4,587 pounds.At its full 1.9 specific gravity rating, it is engineered for a maximum contents weight of about 8,715 pounds.That spread is the point of a heavy-duty vertical tank like this one: the wall thickness supports dense liquids that would overstress a standard 1.0 to 1.9 SG water tank of the same size.The black resin blocks light, which discourages algae growth in stored water and protects light-sensitive contents.Keep in mind the 550-gallon figure is nominal capacity; ASTM D1998 freeboard means the usable volume sits below the brim, and our guide on freeboard sizing per ASTM D1998 explains how density and thermal expansion shape the volume you can actually put to work.To match this tank to a specific volume and stand or containment plan, run the numbers through our Tank Sizing Calculator and review the Tank Sizing Guide before you commit to a pad.

Set it up right

A vertical storage tank this size needs a flat, fully supported base.At 8,715 pounds fully loaded to its rating, the 48 by 48 inch footprint concentrates real weight on whatever it sits on, so a level, continuously supporting foundation is not optional.For a poured base, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework.No fitting configuration is published for this SKU here, so verify outlet size and placement against the technical drawing on this page, or by phone, before you plumb anything, and confirm your fittings and gaskets suit the liquid you intend to store.This is linear polyethylene, which suits water and many bulk-liquid duties, but linear PE behaves differently from crosslinked resin for certain aggressive chemistries, so route any chemical-service question to the drawing and a fittings and gasket confirmation rather than assuming broader resistance.If this tank feeds a private fire-protection or rural water reserve, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and for grey-water, rainwater, or condensate reuse the industrial water reuse tank topology guide lays out quality-banded storage trains.

The mistake to avoid

Do not treat the 1.9 specific gravity rating as a license to skip the math on your actual liquid.The rating tells you the tank can hold a liquid up to 1.9 times the density of water, but the pounds still land on your foundation and fittings.Size the pad and the base for the loaded weight of your real contents, not for water.And plan any secondary containment separately if your application or local regulation calls for it.
