The Snyder Industries 15000 Gallon Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for bulk water reserve where you need serious volume in a fixed footprint. It stands 234 inches tall on a 143 x 143 inch footprint, holds 15,000 gallons in Natural White polyethylene, and carries a 1.9 specific gravity rating. That rating means the wall is engineered to hold a full 15,000 gallons of a liquid up to 1.9 g/cc, so for plain water (SG 1.0) the tank runs well inside its structural margin. This is one of the large white vertical storage tanks in the Snyder line — the kind of unit farms, municipalities, and fire-protection sites specify when a smaller vertical tank simply runs out of capacity.
Will it work for your site?
Filled with water, this tank carries roughly 125,100 pounds of contents; its 1.9 rating supports a maximum rated contents weight near 237,690 pounds. Give your foundation engineer both numbers: design the pad for water service at 125,100 lb, with a structural ceiling of 237,690 lb. A 15,000-gallon vertical tank needs a properly engineered pad — level, full-contact, and never a partial or spanning support — not compacted gravel. Work the footprint (143 x 143 inches) and the loaded weight through our Tank Sizing Calculator, and read the concrete pad sizing framework before you pour. If you are still choosing a capacity, the Tank Sizing Guide walks through matching volume to draw-down and refill rates.
Fittings and access
The tank is configured with a flange, a 12" x 26" fitting, an 18" polyethylene threaded/vented fitting, a flat fitting, and a manway with 15" access for interior inspection and cleaning. Two operational notes: confirm the gasket size and material for the flange and the 12" x 26" penetration against the technical drawing on this page before you order plumbing, and keep the 18" vented fitting unobstructed at all times — on a tank this size, a blocked vent can pull a vacuum and collapse the wall during high-rate draw-down. The drawing is the authority on outlet placement and elevations for this specific tank.
A common mistake to avoid
The single biggest error on a tank this size is underbuilding the base. A tank standing nearly 20 feet tall and weighing over 125,000 pounds full is unforgiving of settlement — an uneven pad concentrates load and stresses the wall. If this reserve is part of a rural fire-water plan, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection, and the industrial water reuse topology guide helps if this feeds a grey-water or rainwater aggregation train.
