The Snyder Industries 1000 Gallon HDPE Vertical Liquid Storage Tank is a 1,000 gallon vertical storage tank molded in white polyethylene, rated to a 1.5 specific gravity and carrying ASTM certification. It stands 81 inches tall on a 64 x 64 inch footprint, so before you commit, confirm your install pad and any doorway clearance against that height and square base. This page answers the three things that decide a 1000 gallon vertical tank purchase: whether it fits your job, what freight will run, and the one sizing detail people miss.
Does this HDPE tank fit your application?
This is a vertical liquid storage tank built from polyethylene with a 1.5 specific gravity rating, which means it is engineered to hold contents up to one and a half times the density of water. Filled to its full 1,000 gallons with plain water, the contents weigh 8,340 lb; at its maximum rated content density the tank is designed to carry up to 12,510 lb. Size your foundation, ring wall, or slab to that 12,510 lb figure rather than the water-only number if you intend to store anything heavier than water. The 64 x 64 inch footprint and 81 inch height make it a standard vertical storage tank profile for water, rainwater capture, and general liquid holding. If you are weighing this size against your actual draw and refill rate, run the numbers through the Tank Sizing Calculator or read the Tank Sizing Guide before ordering. Fitting configuration — outlet, bulkhead, and vent placement — is confirmed at the time of order, so call 866-418-1777 to match the plumbing to your tie-in before the tank ships.
The specific-gravity detail most buyers overlook
This tank carries ASTM certification, and the standard governing polyethylene upright storage tank wall thickness is ASTM D1998. A wall built to that standard is intentionally thicker at the bottom, where hydrostatic pressure is greatest, and tapers toward the top. The mistake to avoid is treating one specific gravity as covering every liquid: the 1.5 SG rating is the ceiling, not a license to ignore density. Match your stored liquid's actual specific gravity against that 1.5 rating, and keep in mind that the vapor-saturated headspace at the top of the tank is where premature wall failures often originate — not the liquid-wetted lower wall most operators inspect. Our guide on HDPE tank wall thickness and ASTM D1998 sizing logic walks through why liquid-side inspection misses these. If you anticipate a denser liquid or need secondary containment that runs past the 1.5 ceiling, the Snyder Captor double-wall freeboard sizing guide explains how thermal expansion and density cut into the volume you can actually use — the right path when this single-wall tank's rating is not enough.
Sizing it into a larger system
A 1000 gallon vertical tank is a common building block in fire-water reservoirs and rural water supply. If you are sizing for private fire protection, NFPA 22 reservoir discipline and cold-climate freeze protection are covered in our fire-water reservoir tank design guide, which pairs naturally with a vertical HDPE tank of this size. For a full walk-through of the spec sheet on a 1,000 gallon vertical, see our 1000 gallon vertical liquid storage tank buyer's guide — confirm the exact diameter, height, and resin color against this SKU's 64 x 64 x 81 inch white build, since 1,000 gallon verticals are offered in more than one profile.
