The Snyder Industries 300 Gallon HDPE Vertical Liquid Storage Tank is a white polyethylene tank built for straightforward liquid storage where you need real capacity in a compact footprint. It stands 80 inches tall on a 35 x 35 inch base, holds 300 gallons, and carries a 1.9 specific gravity rating, so it is engineered to hold liquids substantially heavier than water. For water and general liquid storage, that rating gives you a wide margin of safety.
Will it work for your setup
This is a self-supporting vertical storage tank on a 35 x 35 inch footprint, so plan a level pad or slab at least that size, rated for the loaded weight. Here is the math a skeptical buyer wants visible: 300 gallons of water weighs about 2,502 pounds, and against its 1.9 SG rating the tank is engineered to carry as much as 4,754 pounds of contents. That built-in headroom is what makes this HDPE tank suitable for denser liquids without stepping up to a heavier-rated model. Confirm your pad, ring, or floor can carry the full 4,754-pound load before you fill. If you are still matching tank volume to your draw-down and refill needs, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. Buyers cross-shopping vertical HDPE storage tanks in the 300 gallon class will find the full walkthrough in our 300 gallon vertical storage tank buyer's guide. Review the technical drawing on this page for fitting locations and exact dimensional detail before you plumb it.
One thing not to get wrong
The most common mistake on a tank this size is under-building the base and ignoring the fill weight. A 300 gallon vertical tank is top-heavy when empty and very heavy when full, so it needs a flat, fully supported foundation of at least 35 x 35 inches and, on open or windy sites, tie-downs. Because fitting and bulkhead locations are not called out in the specs here, confirm outlet size and placement against the technical drawing on this page before you buy plumbing. If you are putting this tank into rural fire-water reserve or cold-climate service, the design details matter even more.
Guides worth reading first
