The Snyder Industries 2500 Gallon HDPE Vertical Liquid Storage Tank is a 2,500-gallon white vertical tank molded from high-density linear polyethylene (HDPE) for liquid storage. It stands 107 inches tall on a 90-inch round footprint (90 x 90 in), so before you commit to a location, confirm the pad and any doorway or roofline clears that 107-inch height. Snyder builds this tank to ASTM D1998, the standard that governs HDPE wall thickness and the 1.5 specific gravity rating - meaning the wall is engineered to hold liquids denser than water up to that 1.5 SG limit.
Will it work for your liquid?
Sizing matters here because polyethylene tanks are filled by weight, not just volume. Filled to capacity with water (SG 1.0), this vertical storage tank carries roughly 20,850 lb of liquid. At its full 1.5 SG rating, the contents can reach about 31,275 lb. Make sure your foundation - typically a level reinforced concrete pad sized to the 90 x 90 inch footprint - is rated for that load before filling. If you are still deciding on size, the Tank Sizing Calculator and Tank Sizing Guide walk you through matching gallons to your draw rate and refill cycle.
Fittings and access
This Snyder HDPE storage tank ships with a flange fitting, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access. The flange and the 18-inch threaded port are your inlet, outlet, and vent interface, so confirm the flange bolt circle and the 18-inch threaded port match your pump and fill line before ordering. The vented design matters for any application where liquid moves in and out, since it lets the tank breathe and prevents the vacuum or pressure that can deform a sealed polyethylene wall. Note that some gallonage marks may be removed where fittings are placed - the molded fitting locations take priority over the cast-in volume markers.

The mistake to avoid
The most common error on a large vertical tank like this is underestimating the filled weight and the headspace where polyethylene works hardest. A 2500 gallon tank topped off can exceed 31,000 lb at its rated 1.5 SG - that is real foundation engineering, not a job for bare ground or undersized footings. It is also worth understanding why HDPE walls thin and age fastest at the vapor-saturated headspace rather than down in the liquid; our guide on HDPE tank wall thickness and ASTM D1998 sizing logic explains where premature failures originate and why liquid-side inspection misses them. Because that headspace is where HDPE works hardest, the 15-inch manway is your access point for the periodic interior inspection that guide recommends - and on a tank this tall, it is the only practical way in.

This tank ships LTL freight from the Snyder plant in Marked Tree, AR, and freight is quoted live to your ZIP code. Because a 2500 gallon vertical HDPE storage tank is an oversized LTL load, the real number depends on your delivery point - get it with our Freight Cost Estimator or call 866-418-1777 to lock in your order.
