The Snyder Industries 8000 Gallon ASTM Black Vertical Storage Tank is a full-size bulk water reservoir molded in black polyethylene, standing 186 inches tall on a 120 x 120 inch footprint. It is built to the ASTM standard for vertical polyethylene storage and carries a 1.5 specific gravity rating, so it holds water and heavier-than-water contents without stressing the wall. Before you commit, confirm the site fit: 186 inches of height plus overhead clearance for the 18-inch top fitting and manway access is the real gate on a tank this tall. For anyone sizing a rural fire-water reservoir, an irrigation buffer, or a municipal-scale bulk water store, this is the vertical storage tank that answers "will it hold the volume and stand up over time."
Will it work for your site?
At 8,000 gallons, a full tank of water weighs 66,720 lb, and the 1.5 SG rating means the shell is engineered to carry up to 100,080 lb of rated contents. Plan your pad for that load: the 120 x 120 inch footprint needs a level, engineered concrete base sized for the filled weight, not the empty tank. Our concrete pad sizing guide walks through the ACI framework for above-ground poly tanks. The drawing shows three top penetrations: a FLANGE, an 18" PE THREADED/VENTED fitting, and a MANWAY with 15" ACCESS for entry, cleaning, and inspection. The 18-inch fitting is the combined threaded and vented top penetration, so it doubles as the tank's breathing path and must stay clear. Because pack data carries no gasket or bulkhead dimension, confirm the flange gasket and pipe sizing against the technical drawing on this page before you order. Use the Tank Sizing Calculator and Tank Sizing Guide to match this black tank to your draw rate and reserve target.
The mistake to avoid
The most common misstep on a tank this size is treating the specific gravity rating as a formality. At 1.5, this is the heaviest-contents rating offered here: it covers water at 1.0 with full margin and denser liquids up to the 100,080 lb rated ceiling. That headroom does not license an undersized pad or plumbing. Anchor and pipe for the full 100,080 lb rated load, and give the vented top fitting a clear path so the tank breathes as it fills and drains. For fire-protection reservoirs, size the usable volume against your NFPA draw requirement rather than the nameplate gallons, which our fire-water reservoir design guide covers in detail. If you are aggregating grey water, rainwater, or condensate into a storage train, the water reuse tank topology guide shows how a tank this size fits a quality-banded system.
Freight and how to order
This Snyder vertical storage tank ships by LTL freight from the Snyder plant in Chowchilla, California, and freight is quoted live to your ZIP. Empty, it is a manageable poly shell; full, it holds 66,720 lb of water, so arrange delivery access and unloading equipment for the empty tank and plan the pad and rigging for the filled weight. Because of its height and footprint, delivery details are confirmed at quote time. Get a real number with our Freight Cost Estimator, or call 866-418-1777 and we will size the reservoir, confirm the fittings, and quote freight to your site. See the technical drawing on this page for exact fitting placement before you set your plumbing.
