The Snyder Industries 6900 Gallon Heavy Duty Vertical Storage Tank is built for bulk water storage where every gallon counts and the load on the slab is enormous. Listed in Natural White polyethylene, this vertical storage tank measures 153 in tall on a 120 x 120 in pad footprint and carries a 1.9 specific gravity rating - the structural headroom that earns the "heavy duty" name. If you are sizing a fire-water reserve, an irrigation buffer, process make-up, or a reuse train, this is the kind of large-format white vertical storage tank that anchors the whole system.
Will it work for your site?
At this size, weight is what governs your foundation, so start there. At its rated 6,900 gallons of water, the contents alone weigh roughly 57,546 pounds, and the tank is engineered to a maximum rated contents weight of 109,337 pounds at the 1.9 SG rating. That higher number is why a Snyder heavy-duty wall earns its keep: the 1.9 specific gravity rating means the shell is sized for liquids heavier than water, so plain water service runs well inside the design envelope. It also means you are not buying short - if this storage tank ever needs to hold a heavier-than-water liquid like brine or liquid fertilizer down the road, the 1.9 rating already covers it, with no second tank to purchase. The 120 x 120 footprint at 153 inches of height concentrates that mass over a fixed pad area, so the foundation has to be right before the tank ever arrives.
Foundation and sizing discipline
A tank this heavy lives or dies on its pad. Read our concrete pad sizing guide for above-ground polyethylene tanks and confirm the slab and subgrade carry the full 57,546-pound water load over the 120-by-120-inch footprint before you set it. To dial in the right gallonage for your demand, the Tank Sizing Calculator and Tank Sizing Guide walk you through draw-down and reserve. If this is feeding a private fire-protection stack on a rural or remote site, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection, and for grey-water, rainwater, or HVAC-condensate aggregation the water-reuse tank topology guide shows how a tank like this fits a quality-banded storage train. If you are weighing single-wall against double-wall containment for a heavier liquid, our Snyder Captor freeboard sizing guide walks through the ASTM D1998 freeboard math.
The mistake to avoid
The common error on a tank this large is treating it as a drop-in like a small poly tank. It is not. Confirm the fitting and outlet configuration with us at 866-418-1777 before you finalize plumbing, and check the technical drawing on this page for the tank's dimensional layout. Remember that even a partially filled 6,900-gallon tank still moves real weight. The 1.9 SG rating is your friend on the structural side, but it does not change the foundation math: you are still setting nearly 58,000 pounds of water on one pad. Plan the pour, the access, and the offload before delivery, not after.
This tank ships LTL by motor freight from the nearest Snyder plant in our network - Lincoln, NE or Philippi, WV - with the carrier and cost quoted live to your ZIP. The system routes from whichever plant is closer to you, so an Eastern buyer ships out of West Virginia and a Plains or Western buyer out of Nebraska; that routing is exactly why it pays to run your destination through the Freight Cost Estimator before you decide. Or call 866-418-1777 and we will arrange the LTL quote and offload details for you. A tank this size warrants a quick call to confirm access and equipment at the receiving end.
