The Snyder Industries 10,500 Gallon ASTM Black Vertical Storage Tank (SKU 5330300N49) is a full-size bulk vertical tank molded in black polyethylene, standing 179 inches tall on a 143-inch diameter with a 143 x 143 inch square pad footprint. It carries a 1.5 specific gravity rating, so the wall is engineered to hold contents heavier than water at high volume without over-stressing the shell. It ships from California (Snyder's Chowchilla plant), which is worth noting up front if you're east of the Rockies, since origin drives the freight number. For a large water reserve, a rainwater or reuse train, or a rural fire-water reservoir, this is a high-capacity single vertical tank in the black storage line.
Will it work for your site?
At 10,500 gallons nominal, size the pad and the load before the tank arrives. Filled with plain water it carries roughly 87,570 pounds of contents; at its full 1.5 SG rating the wall is rated for up to about 131,355 pounds of contents. That weight lands on the 143 x 143 inch footprint, so the supporting pad has to be level and sized for the full load, not the empty shell. Our Tank Sizing Calculator and Tank Sizing Guide match volume to duty cycle, the Snyder freeboard sizing guide (ASTM D1998) explains why the 10,500 gal is nominal and usable volume must account for freeboard, and the concrete pad sizing framework (ACI 360R-10) walks through the foundation for an above-ground polyethylene tank this size.
Fittings and access
Per the technical drawing on this page, the tank comes molded with a flange, an 18-inch PE threaded/vented fitting, and a manway with 15-inch access — that is the as-drawn configuration, no separate vent to source. The vented fitting matters on a vertical storage tank this large: fast fill and draw needs to breathe so the head doesn't pull a vacuum or over-pressure. The 15-inch manway access lets you inspect and clean the interior. Confirm the fitting layout against the technical drawing on this page before you plumb the site.
Water storage and reuse duty
This black vertical tank suits high-volume non-potable water storage, industrial process water, and reserve applications where one large vessel beats a bank of smaller ones. Black polyethylene limits light transmission, which helps hold algae growth down in stored water. For rural and remote fire-protection reserves, the fire-water reservoir design guide (NFPA 22 sizing) covers how a polyethylene tank fits the private fire-protection stack, and the industrial water reuse topology guide maps grey-water, rainwater, and condensate aggregation into quality-banded storage trains.
This tank ships LTL freight from Chowchilla, CA, and at 179 inches tall it moves as an oversized load — get a firm delivery number by running your ZIP through the Freight Cost Estimator or calling 866-418-1777. Freight is quoted separately from the tank list price. Confirm your pad and rigging plan for a tank this size before you order.
