The Snyder Industries 3500 Gallon Vertical Water Storage Tank in black is built for high-volume bulk water storage where you need real capacity in a stable, ground-mounted footprint. Molded from High Density Linear Polyethylene and rated to a 1.0 specific gravity, this 3,500-gallon vertical tank is sized for water and water-equivalent fluids - it holds plain water, not heavier chemical solutions. The black resin blocks sunlight to suppress algae growth, which matters for any tank holding standing water outdoors.
Will it work for your site?
This is a vertical storage tank standing 125 inches - 10 feet 5 inches - tall on a 96-inch by 96-inch footprint, so plan for an 8-foot by 8-foot pad and confirm overhead clearance for delivery and final placement. A 10'5" tank plus its vent and top fittings often will not clear a standard doorway or a low building eave, so check gate, door, and roofline clearance before the truck arrives. Filled to capacity, it carries 29,190 pounds of water, so the supporting pad has to be engineered for that static load. Pour a level, reinforced slab before delivery: our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks. Run your fill volume and head height through the Tank Sizing Calculator and review the Tank Sizing Guide to confirm a 3,500-gallon vertical tank matches your draw and refill cycle. For the exact molded heights, fitting locations, and outlet positions, see the technical drawing on this page.
Confirm the fittings before you order pipe
Fitting and gasket sizes are not published for this listing, so confirm the outlet, bulkhead, and gasket spec against the technical drawing on this page or by phone before you order pipe and fittings - do not assume a size with 29,190 pounds of head behind the outlet. After the tank is set and plumbed, fill and hold it before commissioning: with the fittings unpublished, the fill-and-hold leak test is your real acceptance gate for the outlet and gasket seal. The hydrostatic test methodology guide covers water-fill discipline, pad settlement monitoring, and fitting leak detection.
The mistake to avoid
The trap on a tank this size is the specific gravity rating. This tank is rated to 1.0 SG - that is water. Do not fill it with a denser fluid thinking the wall section will carry it; that rating is the structural ceiling, and the maximum rated contents weight is 29,190 pounds. If your stored fluid is heavier than water, you need a higher-SG-rated tank, not this one - call 866-418-1777 or use the Tank Sizing Calculator to spec the right tank for fluids heavier than water. The second trap is the pad: a 29,190-pound full weight on an unprepared or out-of-level base will stress the tank shell and the fittings, so the foundation work is not optional.
Common applications
At 3,500 gallons this black vertical tank suits rural fire-water reserves, agricultural and irrigation supply, rainwater and process-water aggregation, and bulk non-potable water storage staged for distribution. If you are sizing a private fire reservoir, our fire-water reservoir design guide covers NFPA 22 sizing and cold-climate freeze protection. For grey-water, rainwater, and HVAC condensate capture, the industrial water reuse topology guide maps quality-banded storage trains.
This tank ships LTL freight from the nearest Snyder Industries plant - Albertville, AL or Merced, CA - quoted live to your ZIP code. Which plant fills your order depends on stock and your delivery ZIP, and that choice drives the LTL cost, so quote your actual ZIP rather than assuming the nearer plant. Get an exact rate with our Freight Cost Estimator, or call 866-418-1777 to lock in your delivery. Plan for offload at the curb and have equipment ready to position the tank on the pad.
