The Snyder Industries 1000 Gallon ASTM Black Heavy Duty Vertical Storage Tank (order as SKU 1831000N51) is a high density linear polyethylene vertical storage tank built for bulk water and general storage where a tough black wall and a high specific-gravity rating matter. Standing 89 inches tall on a 60 x 60 inch round footprint, it holds 1000 gallons in a compact vertical form that fits tight pads and equipment yards, and its 1.9 specific gravity rating gives real headroom above plain water service.
Will it work for your job
Filled with water, this tank carries roughly 8,340 lb of contents, and its wall is rated to hold up to 15,846 lb at the full 1.9 specific gravity. That spread is the number to check first: water sits far below the tank's structural ceiling, so you keep margin for denser liquids and for the safety factor engineers hold in reserve. Practically, this tank is rated to store liquids up to 1.9 specific gravity, so anything from water at 1.0 through heavier solutions stays inside the wall rating. The 60 x 60 inch footprint is what you design the pad around. Walk through our Tank Sizing Guide and the concrete pad sizing framework before you set forms, and use the Tank Sizing Calculator to confirm 1000 gallons matches your real draw and refill cycle. If you are working the freeboard math for a heavier fill, our Snyder freeboard sizing guide explains how density eats into usable volume.
Fittings and access
Per the technical drawing on this page, this vertical tank comes configured with a flange fitting, an 18-inch polyethylene threaded and vented lid, and a manway with 15-inch access. That 15-inch manway is your entry point for interior cleaning and inspection over the tank's life, which matters on any long-term water tank. The vented lid is just as important on a black tank: it prevents pressure and vacuum swings as the tank fills and drains. Read the drawing for exact fitting locations and heights so your plumbing and overflow lines land where you expect.
Freight and how to order
This is a heavy-duty ASTM-rated 1000 gallon tank, so it ships LTL freight. It ships from the Snyder plant in Chowchilla, California, and freight is quoted live to your ZIP rather than folded into the list price. When you size the carrier and liftgate delivery, plan around the 89-inch height and 60 x 60 inch footprint. Run your delivery address through our Freight Cost Estimator to see the freight number before you commit, or call 866-418-1777 and we will build the quote with you. If you are stacking storage for rural fire supply, our fire-water reservoir design guide covers where a black vertical storage tank fits in the private protection stack.
