The Snyder Industries 8500 Gallon ASTM Black Vertical Storage Tank is a full-size bulk vertical built to ASTM standards for above-ground water and liquid storage. It holds 8,500 gallons, stands 194 inches tall, and sits on a 120 x 120 inch footprint, so it needs a level pad sized to that base before it ever takes on water. Molded in black polyethylene, this vertical storage tank carries a 1.5 specific gravity rating, meaning the wall is engineered to hold liquids up to 1.5 times the weight of water at full volume. The opaque black wall is a deliberate choice for above-ground water storage, cutting the light transmission that lets algae take hold in an outdoor tank.
Will this tank work for your site?
Plan around the weight, not just the gallons. Filled with water this tank carries a full-water weight of 70,890 pounds, and at its maximum 1.5 SG rating the contents alone can reach 106,335 pounds. That load has to land on a pad that can carry it, so confirm your foundation before delivery. One thing to size correctly up front: the 8,500-gallon figure is the rated capacity, and under ASTM D1998 a vertical poly tank reserves freeboard at the top, so your usable draw-down volume is less than the rating — our guide on Snyder freeboard sizing per ASTM D1998 walks through the volume you can actually use. Run your numbers against the Tank Sizing Calculator and the Tank Sizing Guide to match this vertical tank to your draw-down and refill cycle.
Fittings and what to get right
The technical drawing on this page shows the molded-in fittings that come with this tank: a flange, an 18-inch PE threaded/vented top fitting, and a 12 x 24 inch fitting for access. The 18-inch fitting is the threaded, vented connection at the top — on a tank this size, that vent matters for handling vacuum and airflow during fast fill-and-draw cycles. The most common mistake buyers make at this scale is reading the specific gravity rating as headroom for anything. The 1.5 SG rating tells you the tank can physically hold heavier liquids, but the black polyethylene shell is meant for water and general above-ground storage, not chemical service without a compatibility check first. Match your liquid to the wall rating, and size the pad to the full 120 x 120 inch footprint so the base is fully supported.
