The Snyder Industries 400 Gallon Vertical Water Storage Tank in green is a closed-top polyethylene vertical tank built for bulk water storage where you need real volume on a compact base. It stands 80 inches tall on a 40 x 40 inch footprint, so it holds 400 gallons of water while occupying only a 40-inch square of floor or pad space. As a closed-top vertical it fills and vents from the top - roughly 80 inches up to the top fitting - so there is no open lid; plan ladder or platform access for fill and inspection. The green color cuts light penetration to slow algae growth in stored water, which makes this a practical pick for rainwater capture, hauled-water reserves, irrigation supply, and rural fire-water storage.
Will it work for your site
This is a vertical storage tank molded from polyethylene with a 1.0 specific gravity rating, which means it is engineered for water and water-weight liquids - contents at the density of fresh water. Filled to capacity, 400 gallons of water weighs 3,336 pounds, and that is also the maximum rated contents weight, so plan your pad and stand to carry roughly 3,340 pounds plus the tank itself. Because the load sits on a 40 x 40 inch footprint, the surface under it must be level, fully supporting, and rated for that concentrated weight. For a poured base, our concrete pad sizing guide walks through the ACI framework for above-ground polyethylene tanks. If you are still confirming volume against your demand, run the numbers through our Tank Sizing Calculator and the Tank Sizing Guide. Fitting and outlet configuration is confirmed per order - call 866-418-1777 to verify bulkhead and outlet size and gasket spec before you buy.
Common uses and matching the tank to the job
At 400 gallons this Snyder vertical water storage tank suits a wide span of storage work. For private fire protection on rural and remote sites, the fire-water reservoir design guide covers NFPA 22 sizing discipline and freeze-protection engineering for cold-climate service. For grey-water, rainwater, and HVAC condensate capture, our water reuse tank topology guide shows how this kind of vertical tank fits into a quality-banded storage train. If a 40-inch-wide tank cannot pass through your gate or doorway, the 400 gallon green doorway water tank buyer's guide compares the slim-profile alternative at the same capacity.
The mistake to avoid
The most common error on a tank like this is treating the 1.0 specific gravity rating as a formality. It is the design limit: this tank is rated for fresh-water-density contents only. Storing a heavier liquid - anything denser than water - overloads the wall and base beyond what this shell is built to carry, and it voids the tank's intended service. Keep it on water and water-weight liquids. If you need to store a chemical or a liquid heavier than water, this green water shell is the wrong tool - look at a tank rated to 1.5 or 1.9 specific gravity instead. The second mistake is under-building the base: a 40 x 40 inch footprint puts a lot of weight on a small area, so the pad or stand has to be sized for the full 3,336-pound load, not estimated.
