The Snyder Industries 16500 Gallon Plastic Vertical Liquid Storage Tank is a Lincoln, Nebraska-built bulk water reservoir for sites that need serious volume in a single footprint: high-density linear polyethylene, white, 142 inches in diameter and 257 inches tall on a 142 x 142 inch pad. It carries a 1.5 specific gravity rating, which means the wall is built with structural margin above the weight of water, so plain water service runs well inside the tank's rated envelope. If you have been searching for a large white vertical storage tank from Snyder, this is the upper end of the single-tank range.
Will it work for your site?
At 16,500 gallons, full of water this tank carries roughly 137,610 pounds of contents, and the 1.5 SG rating means the structure is rated to hold up to about 206,415 pounds. Those are the numbers your pad and foundation have to answer to before anything else. Loaded with water, that 137,610 pounds spreads over a 142 x 142 inch footprint (about 140 square feet) for roughly 980 pounds per square foot of uniform bearing your slab and subgrade must carry; at the 1.5 SG maximum rating, plan for about 1,475 pounds per square foot. The 257 inch height also drives the overhead clearance you need to set and fill it. Our Tank Sizing Calculator and Tank Sizing Guide help you confirm that 16,500 gallons lands where you want it for your draw rate and reserve.
Foundation and design notes
A vertical tank this heavy lives or dies on the pad under it, so size the slab to the loaded weight, not the empty tank. Walk the concrete pad sizing framework against those bearing figures before you commit a slab design. If this reservoir is part of a private fire-protection or rural water supply, the fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. For reuse and aggregation builds, the industrial water reuse topology guide shows where a tank this size fits in a banded storage train.
The mistake to avoid
The most expensive error on a vertical poly tank this large is under-building the foundation for the loaded weight instead of the empty tank, and the second is assuming wall failures start where you inspect. Premature wall failures on polyethylene tanks tend to originate at the vapor-saturated headspace, not on the liquid side where most inspections look. The HDPE wall thickness guide walks through the ASTM D1998 sizing logic behind that. One more before you pour: fitting type, size, and gasket selection are confirmed per order against the technical drawing on this page or by phone, so call us before you finalize the slab penetrations rather than after.
