The Snyder Industries 20000 Gallon Black Vertical Storage Tank is bulk-scale water storage, molded in polyethylene at a 1.5 specific gravity rating with a black exterior that shades the water column and slows algae growth in outdoor service. At 242 inches tall on a 165 x 165 inch footprint, this is a vertical storage tank sized for fire-water reservoirs, agricultural supply, municipal backup, and industrial process water where a single 20,000-gallon vessel replaces a bank of smaller tanks. For grey-water, rainwater, and HVAC condensate aggregation, our industrial water reuse tank topology guide covers where a vessel this size fits in a quality-banded storage train.
Will this tank hold your water?
Filled to capacity with fresh water, the contents weigh 166,800 pounds, and the tank carries a maximum rated contents weight of 250,200 pounds. Read that 250,200-pound figure as a structural ceiling, not an operating target — straight water or process water at SG 1.0 sits far inside it, and the 1.5 specific gravity shell is what buys that margin. The SG rating is the number to plan around: it tells you the wall is built for liquids up to 1.5 times the density of water. Confirm your pad and foundation are engineered for the full 166,800-pound water load plus the tank's own weight before you fill. The 242-inch height and 165 x 165 inch footprint set your site clearance; check the technical drawing on this page for fitting locations and dimensional detail. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm this vertical storage tank matches your draw-down and refill cycle.
Foundation and site planning
A vessel this size lives or dies on its base. Because the tank is round, the 165 x 165 inch footprint is a 165-inch outside diameter, and a tank holding 166,800 pounds of water needs a pad that spreads that load evenly across the full 165-inch circle — a cracked or under-built slab is the most common and most expensive mistake on a tank this large. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI 360R-10 framework for exactly this case. If this tank is going into a private fire-protection system, the fire-water reservoir tank design guide covers NFPA 22 sizing discipline and cold-climate freeze protection.
Freight and ordering
This tank ships LTL freight from the Snyder plant in Washington Court House, OH, quoted live to your delivery ZIP — a 242-inch vertical tank is an oversize load, so freight is priced per destination rather than published as a flat rate. Get a freight number in seconds with our Freight Cost Estimator, or call 866-418-1777 to line up delivery access and offloading for a tank of this scale. Order the 20000 gallon black vertical storage tank on this page, and reach out before you finalize your pad so the footprint and load numbers are locked in first.
