The Snyder Industries 12,500-gallon vertical storage tank is a Black, high-density linear polyethylene tank rated to 1.5 specific gravity, built for high-volume bulk water and heavier-than-water service. It stands 198 inches tall on a 142-by-142-inch footprint, which works out to roughly an 11.8-by-11.8-foot pad for site planning. The 1.5 SG wall thickness is the spec that defines what this vertical tank can actually hold, so the numbers below are the ones to confirm before you set the pad, plumb it, and budget freight.
Will it work for your site?
This is a vertical storage tank with a 12,500-gallon nominal capacity in a single Black, HDLPE body. Filled with plain water, contents weigh about 104,250 lb; at the full 1.5 SG rating the tank is built to carry up to 156,375 lb of contents, which is the figure that matters if you are storing a fluid denser than water.
The technical drawing on this page shows a manway with a 15-inch access opening, an 18-inch PE threaded/vented fitting, a flange, a flat fitting, a 12-inch by 30-inch fitting, and a bulkhead. The 15-inch manway access is the entry point for interior inspection and cleaning on a 198-inch-tall tank, so factor that dimension into your confined-space and maintenance plan. The 18-inch threaded/vented fitting handles venting; confirm it is sized to your pump's fill and draw rate, since on a 12,500-gallon tank vent capacity has to keep up with flow to avoid pulling vacuum or building pressure against the wall. Confirm all fitting locations and sizes against the technical drawing before you finalize plumbing, since outlet height and bulkhead placement drive your manifold and overflow design.
Foundation and sizing
At 142 by 142 inches the footprint is square, and at 198 inches tall fully loaded this is a heavy vessel, so the pad has to be engineered for the full 104,250-lb water weight (or 156,375 lb at 1.5 SG) plus your safety factor. Work the pad through our concrete pad sizing guide using the ACI 360R-10 and ACI 318 framework, and use the Tank Sizing Calculator and Tank Sizing Guide to confirm 12,500 gallons matches your draw-down and refill cycle. If this tank is feeding a rural fire-protection stack, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and our water reuse topology guide walks through banded grey-water and rainwater storage trains.
The mistake to avoid
Match the SG rating to your actual fluid before you buy. This vessel is rated to 1.5 specific gravity, meaning its wall is sized for fluids up to 1.5 times the density of water — it is already the higher-SG tier, so for anything between 1.0 and 1.5 SG, including brine and other heavier-than-water fluids, you do not need to hunt for a heavier-rated tank. A tank rated for a lower specific gravity at the same gallonage has a thinner wall and can fail under a heavier load, so do not under-spec the SG rating. If you are only ever storing plain water, the 1.5 SG rating is extra structural margin. One more check before you plumb it: the flange and bulkhead connections require gaskets rated for your stored fluid and temperature, so confirm gasket material against your fluid first.
This tank ships LTL from the Snyder plant in Lincoln, Nebraska, on its own freight quote rather than a flat rate. Because of the 198-inch height and loaded weight, freight is quoted live to your delivery ZIP through our Freight Cost Estimator or by phone at 866-418-1777. Have your ZIP, delivery access, and whether you need a liftgate ready, and our team will line up the carrier for this 142-by-142-inch footprint vertical storage tank.
