Snyder Industries 5000 Gallon Plastic Vertical Water Storage Tank

The Snyder Industries 5000 Gallon Plastic Vertical Water Storage Tank (SKU SII-32821) is a green polyethylene vertical tank built for high-volume water storage, standing 159 inches tall on a roughly 102-inch diameter footprint (102 x 102 inch bounding square). It carries a specific gravity rating of 1.0, which means it is engineered for the weight of water and water-density liquids - the correct rating for a dedicated water storage tank of this size.

Will it hold what you need it to?

At its full 5000-gallon capacity, a tank of water weighs 41,700 pounds, and that figure is also the maximum rated contents weight - so water at SG 1.0 already brings this vertical storage tank to its design ceiling, with no margin for denser fluids. Plan your pad and your site logistics around that 41,700 lb full-fill load, because the weight the ground sees at full capacity is substantial. Before you commit to placement, run your numbers through the Tank Sizing Calculator and review the Tank Sizing Guide to confirm 5000 gallons matches the draw-down schedule your application actually calls for. Whether this is for fresh water storage, irrigation reserve, or a bulk water storage tank feeding a larger system, the 159-inch height and ~102-inch round footprint determine the headroom and slab you need to prepare.

Setting it on the right foundation

A vertical storage tank this size demands a properly engineered base. With more than 41,000 pounds bearing down at full fill, the pad is not an afterthought - it is the difference between a tank that lasts decades and one that settles and stresses. Our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework for getting that round foundation right, and once the tank is set, the hydrostatic test methodology for new-install acceptance shows how to fill, monitor pad settlement, and confirm there are no leaks at any installed fittings before you put the tank into service.

Common-sense planning for large water storage

The mistake to avoid on a tank this large is treating the SG 1.0 rating as a license to store anything liquid. This tank is rated for water-density service - SG 1.0 - so it is sized for water and water-like fluids, not heavier chemical solutions. If your application is fire protection or rural reserve, our write-up on fire-water reservoir tank design covers NFPA 22 sizing and freeze protection for cold-climate sites. If you are aggregating grey-water, rainwater, or HVAC condensate, the guide on industrial water reuse tank topology maps out how quality-banded storage trains fit together.

This tank ships LTL freight from the Merced, CA plant, with freight quoted live to your ZIP code. Get your exact number with the Freight Cost Estimator, or call 866-418-1777 to talk through delivery, site access, and offload for a tank this size. Because a loaded 5000-gallon tank moves as oversized freight, confirming your delivery access ahead of time saves you time and trouble on install day.
