The Snyder Industries 10,500 Gallon HDPE Vertical Liquid Storage Tank is a Chowchilla, California-built polyethylene tank engineered to ASTM standards for large-volume bulk water and liquid storage. Standing 179 inches tall on a 143 x 143 inch footprint, this white vertical storage tank holds 10,500 gallons and carries a 1.9 specific gravity rating, meaning the HDPE wall is sized for liquids substantially heavier than water. That gives you real margin: water fills it to roughly 87,570 pounds, while the tank is rated to carry up to 166,383 pounds of denser liquid. One unit can serve potable, fire-water, or general bulk water duty today and be repurposed for heavier liquids up to that 1.9 SG rating later, without stepping up to a more expensive heavier-walled tank.
Will this vertical tank work for your site
Plan your pad before the truck arrives. At 179 inches (14 feet 11 inches) tall with a 143-inch (just under 12-foot) diameter, this is a tall vertical storage tank that needs a level, engineered foundation rated for the full load, not the empty weight. Filled with water the contents alone weigh approximately 87,570 pounds, and the 1.9 SG rating means the tank is built to safely hold up to 166,383 pounds of denser liquid. Your foundation and any secondary containment must be designed around those numbers. Use the Tank Sizing Calculator and Tank Sizing Guide to confirm 10,500 gallons fits your fill-and-draw cycle, review the Snyder freeboard sizing guide for containment and usable-volume math, and read the 10,500 Gallon Vertical Liquid Storage Tank buyer's guide for application-specific planning.
Fittings and access
This vertical tank is configured with a flange fitting, an 18-inch polyethylene threaded and vented fitting, and a manway with 15-inch access for entry, inspection, and cleaning. Confirm the exact fitting locations and elevations against the technical drawing on this page before you set your inlet, outlet, and overflow plumbing. The 18-inch threaded port and the manway are the two interfaces you have to mate to, so verify your thread, flange, and gasket mating hardware against your plumbing before ordering, and call 866-418-1777 to confirm fitting and gasket availability. The threaded and vented top fitting matters on a tank this size: as it fills and empties, large volumes of air move in and out, and proper venting prevents pressure or vacuum from stressing the wall. For why headspace and wall thickness drive long-term tank life, see our guide on HDPE tank wall thickness at the vapor-saturated headspace.
The mistake to avoid
The most common error on a tank this large is under-building the foundation. Operators size the pad for water weight and forget that the tank is ASTM-rated to a 1.9 specific gravity. If you ever store a denser liquid, or simply want the full safety margin the tank is built for, your foundation has to carry up to 166,383 pounds. Engineer the pad and any secondary containment for the rated load up front, because retrofitting a foundation under a full 10,500-gallon tank is not a project you want. If this tank is destined for fire-protection reserve or rural water supply, the fire-water reservoir design guide walks through NFPA 22 sizing and freeze protection.
This 10,500 gallon vertical HDPE storage tank ships LTL freight from the Snyder plant in Chowchilla, California, and freight is quoted live to your ZIP. West Coast sites are nearest this plant and tend to see the most favorable freight; East Coast destinations should expect a longer haul on a load this size, so get your number on the Freight Cost Estimator or call 866-418-1777 before you budget. At 14 feet 11 inches tall this likely moves as an oversized, permitted load, so plan delivery access and crane or large-forklift offload at the receiving end. Listed before freight; reach our team at 866-418-1777 with questions on fittings, foundation requirements, or scheduling your delivery.
