The Snyder Industries 10500 Gallon Black Vertical Water Storage Tank is built for high-volume bulk water service at sites where a single large reservoir beats a bank of smaller tanks. It holds 10,500 gallons in a black polyethylene shell rated to a 1.0 specific gravity, standing 170 inches tall on a 142 x 142 inch footprint. This is the kind of vertical storage tank specified for fire-water reserves, irrigation supply, industrial process water, and rainwater or reuse aggregation where capacity and a stable, opaque tank wall matter.
Will this tank work for your site?
At a 1.0 specific gravity rating, this tank is matched to water and other contents at or below the density of water. It is rated for water and lighter; it is not rated for chemicals or any contents denser than water. If your application calls for a specific gravity above 1.0, step up to a heavier-rated tank rather than running this one out of spec. Plan your pad and structure around the loaded weight, not the empty shell: filled to capacity with water it carries roughly 87,570 pounds of contents, which is also its maximum rated contents weight. That figure drives your foundation design. A flat, level, fully supporting pad sized for the 142 x 142 inch footprint is essential, and our concrete pad sizing guide walks through the ACI 360R-10 framework for above-ground polyethylene tanks of this scale. The opaque black wall blocks light through the shell.
Fittings and access
The tank comes fitted for real plumbing. Per the technical drawing on this page, it carries a flange, a 12" x 30" fitting, a 2" bolted polypropylene fitting with EPDM gasketing, a 1-1/2" Eco bulkhead fitting with EPDM, and an 18" polyethylene manway with a 4" vent and tie-down. The EPDM elastomer on both bulkhead-style fittings is the supplied gasketing for water service. As a starting point for layout, the 2" bolted PP fitting suits a primary fill or suction line and the 1-1/2" Eco bulkhead suits a secondary draw or drain, but confirm every fitting location, size, and elevation against the drawing before you set the tank and run your lines. The 4" vent on the manway is important: a tank this size moves a large volume of air during fast fill and draw, and the vent must stay clear to prevent vacuum or pressure on the shell. The 18" manway also gives you a worker access point for interior inspection and cleaning, which matters on a vessel standing more than 14 feet tall.
Sizing and commissioning
If you are still settling on capacity, the Tank Sizing Calculator and Tank Sizing Guide help you match drawdown and refill rate to your demand. For fire-protection reserves, our fire-water reservoir design guide covers NFPA 22 sizing discipline and cold-climate freeze protection. Sites aggregating grey water, rainwater, or HVAC condensate should review the industrial water reuse topology guide. Use the manway tie-down to anchor the tank: an empty 170-inch-tall poly shell on a 142-inch base is a real wind and uplift risk before it is filled, so secure it as part of set and commissioning. Once installed, follow our hydrostatic test methodology to fill in stages, monitor pad settlement, and check every fitting for leaks before you put the tank in service.
The mistake to avoid
The most common error on a tank this large is underbuilding the foundation. Nearly 88,000 pounds of water has no tolerance for a pad that is undersized, unlevel, or not fully supporting across the entire 142-inch base. A high or soft spot concentrates stress in the shell and can cause premature failure. Pour and cure the pad correctly, verify it is dead level, and fill in stages while watching for settlement.
This tank ships LTL freight from the nearest Snyder Industries plant in our network, either Lincoln, NE or Philippi, WV, with the carrier matched to the destination. At 170 inches of tank height plus the trailer deck, a load like this approaches over-height in many states, so delivery can involve oversize handling, permits, and the right offload equipment on site. Freight is quoted live to your ZIP code, never bundled into the list price. Get a freight estimate with our Freight Cost Estimator or call 866-418-1777 to talk through access, offload, and lead time on a tank of this size.
